Using Brown's gas to heat a home

Getting Brown's gas

Let's figure out where this gas comes from. There is a device called the Brown gas generator - it is designed to produce the very gas that the Internet community is so actively discussing. This invention made it possible to reduce the cost of hydrogen production and significantly reduce the amount of harmful emissions. Under the influence of alternating current, water is split into independent components, into two hydrogen atoms HH and an O (oxygen) atom. In scientific terms, this method is called electrolysis of water, which results in a gas with the chemical formula NHO.

In order to split water by electrolysis, it is necessary to spend 442.4 kilocalories per mole. As a result, from one liter of water you will get 1866.6 liters of detonating gas. When hydrogen is burned after reacting with oxygen, 3.8 times more energy is returned than was expended on its production. By extracting hydrogen in this way, it can be used to supply energy to buildings and structures.

Many fellow citizens, having heard a lot about such a system, have questions:

1. Is it possible to use a rattler for heating a house?
2. How much Brown's gas is released during electrolysis?
3. How will the combustion process occur?
4. Is there a ready-made patented device on the Russian and Foreign markets that will convert water into “rattle”?
5. Of course, many are still concerned about the cost-effectiveness and safety of such a system.

Heating houses with Brown gas, due to its novelty, has not yet become widely used. Manufacturers of hydrogen boilers are just beginning to gain momentum in their production and supply to the Russian and Western markets.

Do-it-yourself Brown's progressive gas: diagram and drawings

There are ready-made generators on the market. But the equipment is expensive, and the efficiency is low. If you wish, you can do the installation yourself.

Water generator circuit:

• Tubes or plates of different diameters made of stainless steel;
• Heating element power regulator;
• Container serving as a desiccant;
• 12 Volt current source.

A clear example of the design can be seen in the drawing. The frequency of current supply determines the efficiency of gas production. Pulses are sent to the tubes, where fuel is produced. The gas then moves into the drying tank and then into the coolant supply circuit. Due to the absence of a combustion process, this heating option is considered environmentally friendly. Gas is created through a chemical reaction. The result is steam, which acts as a coolant.

Mechanism of action

In the process of obtaining gas for heating, electrodes are lowered into a container filled with water, the role of which is played by plates or pipes made of alloy steel. They are then connected to a source of electricity.

The connection must be made taking into account that the potential of adjacent plates is opposite. Only under the condition of alternating positive and negative charges will the decomposition of a mixture of hydrogen and oxygen into individual molecules occur.

Electrical pulses are applied to the plates, and gas is produced. First, it enters the drying tank, then passes into the coolant supply circuit. The steam generated as a result of a chemical reaction is an environmentally friendly fuel for heating homes.

The Brown generator cannot operate on purified water, which has dielectric properties. To ensure the constant passage of electric current through the liquid, salt, soda or caustic potassium were previously added to it. The introduction of such impurities sharply increased the amount of current consumed, while simultaneously reducing the efficiency of the device to such a level that its use as a heat generator became unprofitable. The solution was to use a different design for a source of electrical impulses, including:

• 12 V power supply;
• rectifier with a current of 10 A;
• two resistors with a resistance of 10 and 2.2 kOhm;
• potentiometer with a resistance of 10 kOhm;
• transistor model 838 or 2n3055;
• two coils on a single body;
• capacitor with a capacity of 50 µF.

Make your own Brown Gas Generator

The numbers shown are approximate. When creating a generator, preliminary calculations should be made based on the size of the heated room and the parameters of the electrical network.

Project Charge

Comrades, we continue our experiments with hydrogen. Description and discussion here.

Prospects for using the technology: - highly efficient gas cutting, gas welding; — significant fuel savings on vehicles (special attention to commercial vehicles, for example, truck tractors - this should be of great interest to owners of transport companies and simply long-distance trucks); — reduction of fuel consumption of power plants operating on liquid and gaseous fuels; — reconstruction of outdated boiler houses — the addition of NNO reduces consumption and makes the exhaust non-toxic; — heating on NNO; — creation of fundamentally new generators and engines.

We are dealing with an oxygen-hydrogen mixture, or HHO, or detonating gas, or Brown's gas (some do not like this name, claiming that he took credit for the discovery of this gas, but nevertheless, there is such a name). This gas is obtained by electrolysis of water, i.e. in fact, fuel is around us in unlimited quantities, if we find a way to split water into its components with minimal cost. This is what all the followers of Stanley Meyer and other legendary personalities are doing. The degree of success is difficult to judge - mostly these are the same videos, “secret schemes”, endlessly copied and re-posted online, but sometimes something new appears. When trying to communicate with the “authors” of these technologies, some turn out to be scammers, some are schizophrenics, some simply do not know how to make basic measurements, and some vigilantly guard their secrets. There is only one way out - we will go our own way)

What needs to be clarified is that we can currently measure the gas output, but how much energy is contained in a unit volume of this gas is unknown until we obtain heat or mechanical work.

For example, here: you can find out the highest calorific value of hydrogen: 13,000 kJ/m3 (and for butane - 133,000!) Higher Calorific Value = Gross Calorific Value = GCV - the amount of heat released during complete combustion of fuel, cooling of products combustion to the temperature of the fuel and condensation of water vapor formed during the oxidation of hydrogen included in the fuel.

That is, this is the heat released during the combustion of fuel in some ideal boiler, an ideal unattainable in practice. But, besides this, there is one more subtlety - the data are given for the combustion of fuel in air, that is, a complex mixture of atmospheric gases, where oxygen is about 21% and nitrogen -78%. It is known that when pure oxygen is supplied, the flame temperature increases significantly. And HNO is a mixture of hydrogen and oxygen in ideal proportions for combustion, plus water vapor. Firstly, this very value of the gross calorific value for a given gas is unknown (if anyone knows about such research, please let us know) and secondly, it is unknown how much water vapor is simultaneously produced in a particular device. For example, an “inventor” can build a “boiler” and be happy that he received a large output of gas.

When I receive a rattle. Firstly, it is necessary to observe increased safety measures: - the mixture instantly detonates with a deafening bang and the release of energy, smashing everything to smithereens. therefore, no tanks or bubblers made of fragile plastic, which can produce sharp fragments; - under no circumstances allow gas to accumulate in any container, immediately consume all the gas that is produced, and stop the laser if there is no need for gas, or arrange for gas to be discharged to the street; - do not install the electrolyser in the basement, ensure the natural release of hydrogen upward, and avoid unventilated “pockets” under the ceiling.

The combustion of this gas also has its own characteristics; it can be burned both openly and in a closed volume, because the combustion of LNO does not require an air supply. We will try different options for both burners and hot water boilers.

There are a lot of rumors and even myths regarding the operation of internal combustion engines at NGOs that need to be verified. The first step is to experimentally check how much the power developed by the internal combustion engine increases with the addition of NNO, and accordingly, how much the main fuel supply can be reduced to obtain “standard” power. Naturally, the question of power supply to the electrolyzer arises. The following methods are practiced: 1. Power the laser from a generator driven by an internal combustion engine. for this you will need either an electrolyzer with a low power consumption (most of the commercially available NDC kits for cars), or replacing the generator with a more powerful one. In general, replacing a burnt-out generator is a common case for such experiments, so be careful; 2. Installation of an additional generator that runs only on the electrolyzer (for example, instead of an air conditioner). Here it is necessary to clarify whether the signal from the second generator will affect the on-board network, but overall the idea is interesting; 3. A more exotic way is to power the electrolyzer from a separate battery, and charge it while parked, a kind of hybrid option. This option is especially suitable for those who are interested in the topic, but who are confused by the energy balance - after all, the generation of current for the laser takes away part of the power of the internal combustion engine. The official version of the technology’s supporters is this: yes, power is taken away, but the addition of NNO significantly improves the combustion conditions of the fuel-air mixture, which increases engine efficiency. In addition, the emission of harmful gases is significantly reduced, and the internal combustion engine is cleaned of harmful deposits.

Along the way, problems arise with the engine control system, especially those equipped with a lambda probe (the probe shows an increased oxygen content in the exhaust gases, the control unit increases the fuel supply). Hence, as a consequence, various “deceptions” of the lambda probe signal and other tricks arise. It is difficult to judge how effective such interventions are in the control system developed at the factory, but one thing is clear - the simpler the engine, the easier and more effective the use of this technology. On a carburetor, for example, fuel consumption is regulated by reducing the cross-section of the jet, and there are no problems at all with the electronics. Owners of injection cars of the “pre-lambda era” were also incredibly lucky). In addition, on simpler engines, and especially on older, worn ones, the effect of improved fuel combustion will be most obvious.

In any case, the possibility of operating an internal combustion engine entirely on LNO seems unlikely, since engines are designed for a specific type of fuel. The option of adding gas in order to increase the efficiency of fuel combustion, reduce toxicity and consumption seems more likely.

This concludes the introductory part, then our experiments and reports on them.

Homemade device

If you wish, you can learn how to produce Brown's gas yourself. It is not difficult to make a device for its production with your own hands. To do this, you need to use stainless steel plates, which should be cut into rectangles. In each sheet, at a distance of 3 cm from the edge, you need to make holes about 50 mm in size and solder the electrical cable.

Next, you will need to prepare two square plates of plexiglass measuring 20x20 cm (3 cm thick) and several rubber rings, the outer diameter of which will also be 20 cm. Mounting holes should be provided in the metal and glass sheets.

When all parts of the structure are ready, you can proceed to assembling the device. Between the two steel plates it is necessary to place a rubber ring, pre-treated with a sealing compound, and secure everything with bolts. To the two sides of the resulting part you need to attach sheets of plexiglass with holes for water inlet and gas outlet. Tubes and fittings should be inserted into them.

In a homemade generator, you must make two water jams, otherwise the resulting gas will begin to move in the opposite direction, which will lead to an explosion of the device. The tubes must be positioned so that one is completely immersed in water, and the second is above the liquid level and directed towards the burner. During the decomposition of the liquid, the resulting gas will move through them to water jams.

In order for the efficiency of a home-made heating device to be sufficient to heat a home, it must be used correctly. It is better to use distilled water and sodium hydroxide as starting materials. Before starting the device, apply a soap solution to the plates and then wipe them with alcohol.

During electrolysis, sediment will form on the walls of the generator and electrodes. The best way to remove it is with sandpaper.

Brown's gas and cars

At the moment, Brown gas generators are actively used in the car enthusiast market. We all know that fuel in an internal combustion engine does not burn efficiently. 40% of the fuel burns in a car engine and the remaining 60%, one might say, flies into the air. This system provides a strong increase in engine power, which allows you to save gasoline and also reduces the amount of harmful emissions into the atmosphere, which has a beneficial effect on our environment. Unfortunately, today hydrogen generators can practically only be used for cars. For the heating system, industrial generators cannot be used. They are still poorly adapted for this and not fully developed. Moreover, the choice in stores is very scarce and small.

Advantages of this system over analogues:

• Full automation of the process;
• Automatic stabilization of parameters;
• Automatic control of gas production according to engine needs;
• Fast-acting self-healing protection;
• Simple and clear signaling of electrolyte density and performance;
• Gas purification from unwanted impurities;
• Everything necessary for installation is included;
• Smooth start and automatic shutdown when the engine is not running;
• For injection vehicles, the system is equipped with a module capable of accurately maintaining the specified composition of the fuel mixture;
• Consultations on all issues of setup and maintenance on-line.

Principle of operation

Fuel combustion in internal combustion engines is not efficient. In the best case, only 40% of the fuel (diesel or gasoline) is burned in the car engine, the remaining 60% burns out in the exhaust pipe. Think about it, the efficiency of a modern engine is no more than 20% at the most optimal operating conditions.

Brown gas generator (this gas is also called: brown gas, HHO gas, water gas, hydrogen, di-hydroxide, hydroxide, green gas, Klein gas, oxyhydrogen) is designed to produce gas, which is used to intensify the combustion process in internal combustion engines. Due to combustion intensification phenomena, significant fuel savings and an increase in engine power are achieved. Another advantage of this system is the reduction of harmful engine emissions, which improves the environment.

Brown's SuperAquaCar (SAC) gas generator consists of an electrolyzer (electrodes are made of special grade acid-resistant stainless steel that has undergone electrochemical treatment), a circulation tank, a control system (modulator), and a fuel mixture optimizer (for injection cars). The gas release method is based on the phenomenon of water electrolysis . The circulation tank is designed to separate gas from water, as well as supply the gas generator with electrolyte.

In the electrolyzer, a chemical reaction of electrolysis occurs with the release of hydrogen and oxygen (Brown's gas) from a special electrolyte consisting of distilled water and a catalyst. The chemical formula of our catalyst is such that it is not released with gas, but remains in the water, which eliminates the possibility of it getting into the engine. The resulting gas exits through a tube from the upper fitting of the electrolyzer and is directed into a separate container - a “water seal”, entering from its lower part, there it is cleared of foam and rises above the water level in the form of gas, from where it flows through a moisture filter and through a check valve into the air filter. manifold and then into the combustion chamber. Also, from the “water seal”, water flows through the second tube through the lower fitting back into the electrolyzer, thus circulating liquid throughout the system.

Figure 1. Production of brown gas by electrolysis.

As a result of gas combustion, dry water vapor is formed, which in turn cleans the valve-piston group from carbon deposits, improves the heat transfer between the seat and the valve, which helps to increase the engine life. It also reduces engine oil contamination and increases service mileage.

Gas production is controlled by a modulator (PWM), depending on the crankshaft speed and the temperature of the electrolyser. The modulator is an intelligent electronic device that allows you to use resonance phenomena in the electrolyzer.

Thanks to a special method of current modulation, maximum system performance is achieved. It also provides for a reduction in energy consumption and gas production when the crankshaft speed is reduced; this function prevents battery discharge and relieves the load on the vehicle's electric generator. On modern cars, a decrease in energy consumption at idle also entails a slight decrease in fuel consumption, since the generation of electrical energy is accompanied by an increase in the supply of fuel to the engine, which is used to maintain the nominal crankshaft speed.

Since the combustion process of fuel with Brown gas improves, for maximum fuel economy in the engine, it is advisable to adjust the fuel mixture in comparison with the normal mode without sacrificing power. In this regard, we have developed a fuel mixture ratio optimizer. The optimizer helps to bring the engine to the most optimal mode when working with Brown gas, so that the highest possible efficiency can be achieved. ChIP tuning can also be used to correct the fuel mixture.

Each liter of water expands by 1866 liters of combustible gas. You will not need to carry a gas cylinder with you, but only a liter of water in a container under the hood! One liter of water is enough for 30 - 40 hours of driving.

Questions about our equipment

1. How safe is the equipment?

When installed correctly, our equipment is completely safe. When the engine is stopped, no gas is produced at all, which prevents it from igniting. In addition, there is no gas container. From a chemical point of view, the SuperAquaCar system uses feathers to clean the gas from unwanted impurities, so corrosion is not observed.

As for corrosion during the combustion of brown gas, note that literally all the cars that catch your eye have water pouring out of the exhaust pipe, which is formed during the combustion of ordinary gasoline, and draw your conclusions...

2. Who is the manufacturer and developer?

We are manufacturers and developers of these products. The idea for Brown's gas generators came from abroad.

3. I assembled such a system, but did not get any effect. Why should yours have an effect?

This is not surprising; the simplicity of Brown's gas generation systems is only apparent. The ratio of energy expended to the amount of gas and the quality of the gas are of great importance. In addition, in most cases it makes sense to optimize the fuel supply and gas connection method. The condition of the engine and driving style play an important role.

4. I have seen such systems. They quickly fail, and the electrolyte turns brown!

This applies to systems that have wafers that have not been processed. Our plates undergo special electrochemical treatment, due to which their useful area is increased, and a special coating 20 microns thick is applied to their surface.

We guarantee that the electrolyte in our system will be completely clean and transparent; the service life of our electrolyzer is several years.

5. What are the guarantees?

We guarantee the economic effect of using our products. We will return your money within 10 days after purchasing the system if the purchased system does not give the declared effect and provided that the system is not damaged, we will return your money for the system.

The warranty period for our equipment is 1 year.

General issues

1. How can Brown gas improve efficiency? Will there be a loss of power in my car?

By adding Brown's gas to the fuel system of an internal combustion engine, the combustion of gasoline (or diesel) is improved. You get better efficiency, more horsepower and more mileage with the same amount of gas. The gas generator uses electrical energy from the engine, which is extracted from fossil fuels, but the gain in engine efficiency exceeds the energy cost of generating the electrical energy.

Gasoline savings occur due to better combustion of gasoline. Typically, only about 15% of gasoline's available energy is converted into mechanical energy in an internal combustion engine. The addition of Brown's gas results in better fuel combustion and allows available energy to be extracted from gasoline and converted into mechanical energy, which does not violate the laws of thermodynamics.

2. Why is Brown's gas, as a fuel, better than pure hydrogen?

Currently, the environment is experiencing serious problems, and one of them is the loss of atmospheric oxygen. Its content in the air becomes so low that in some regions it poses a threat to human existence. The normal oxygen content in the air is 21 percent, but in some regions it is several times lower! If we don't take action, the decrease in oxygen in the air will eventually affect each of us.

Produced by electrolysis, Brown's gas can supply oxygen to the atmosphere, while other technologies either have no effect on the atmosphere (such as using pure hydrogen or fuel tanks) or pollute it (such as using fossil fuels). Therefore, we believe that this technology should be chosen to provide fuel for vehicles in the near future.

3. Which electrolyzer is better?

There is no perfect electrolyser. However, the two most important metrics when comparing electrolysers are their efficiency, in other words, how much gas is produced for a given power applied, and whether the electrolysers overheat or not.

Some electrolysers produce impressive gas output, but it is not known how much energy was expended or how such electrolysers were heated. Knowing the current consumption and gas output, one can judge the efficiency of Brown gas generation.

Excessive heating of the electrolysis cell can lead to a sharp increase in the concentration of water vapor - such gas is considered to be of poor quality. Therefore, the “golden mean” is important, in which indicators such as power consumption, degree of heating, dimensions, and gas output are optimally combined.

Typically, an electrolyser consisting of separated cells in series is most efficient for direct forced electrolysis. An electrolyser in the form of a communicating tank will never be as efficient as an electrolyser made of serial cells due to leaks between distant electrodes, which leads to increased heating of the device. Such electrolyzers can heat up to 90°C in just 2 hours. Excessive heating also means that energy is not being used efficiently.

Systems whose electrodes are made of acid-resistant stainless steel show maximum reliability during operation. Systems whose electrodes are made of wire or other types of steel show the lowest reliability.

4. What Brown Gas Generation Systems Are Available?

We produce the following systems:

Brown gas generator kit which includes an electrolyzer with separate cells, a current modulator, an optimizer. etc.; A simple “wet” electrolyzer for 12V voltage, dimensions 120x320x120; The electrolyser is “dry”; Electrolyzer with separate cells. All types of electrolysers can be connected together to increase gas production.

To obtain the maximum possible effect of saving your fuel, you can use a current modulator in resonance mode, an optimizer, a fuel activator, and special additives.

5. Which gas generator do you recommend for my car?

If your engine volume is more than 2.5 liters, we recommend you a gas generator with a capacity of more than 2 liters of gas per minute.

6. How difficult is it to install a gas generator?

Detailed instructions are supplied with each device sold, and a high-quality installation procedure will take no more than 4 hours; if the kit includes electronic components, add another 3 - 4 hours.

7. Where to install the electrolyzer?

Any place, but preferably in a place where the electrolyzer will have a constant air flow in order to reduce its temperature as much as possible.

8. How to introduce gas into the engine?

The hose coming from the water seal must be connected to the intake manifold before the air filter. Also, the filter will protect the engine from random micro drops that may carry traces of electrolyte. The filter also protects the gas generator from accidental backfires.

9. Do I need an optimizer (EFIE)?

If you have a car with fuel injection, the optimizer will adjust the fuel injection. Thus, an optimal mixture of gasoline/gas/air is created, which will further improve the efficiency of your engine.

10. What is the maximum current consumption (amps), how much current can my engine generator supply?

Each engine has an optimal point at which the energy gain due to the addition of Brown gas is maximum. If your electrolyzer draws too much current, you will need to install either a more powerful generator or a current modulator. Less desirable is to reduce the catalyst concentration by adding water.

11. What water should I use?

We recommend distilled water, since water with unknown contaminants may cause electrode bridging.

If you choose to use tap water, you do so at your own risk and we recommend that you clean the electrolyser at least once every 3 months. If your water contains too many salts, it can “poison” the electrodes, which can reduce gas output.

12. How do I manage the current draw (amps)?

The current can be controlled by changing the density of the electrolyte and to stabilize the current between 15-20A you need to add 20g of catalyst for every liter of water. In our systems, this is done by a current modulator (PWM), which regulates and stabilizes the current depending on the operating mode of the engine.

To set the current you will need an ammeter with a measurement range of up to 30A.

Disconnect the negative wire of the electrolyzer from the negative power supply; Connect the positive wire of the ammeter to the “-” terminal of the electrolyser; Connect the negative wire of the ammeter to the car body; Then you need to select the concentration of the catalyst such that you get a current of about 15A with the engine running. Setting up with a modulator with a built-in current sensor:

Make a weak solution using distilled water and a catalyst; Fill the electrolyser with water through the circulation tank; Start the engine. No more than 15 seconds after startup, the “operation” indicator on the front panel of the modulator should light up, the “norm” indicator should not light up; Every 10 minutes, add 30 g of catalyst until the “norm” indicator lights up. The “norm” indicator light means that the peak current (or the current that will be at 100% load) has reached 20A (or 25A - depending on the setting modulator). If, after you start the engine, the “running” indicator does not light up, you should adjust the initial current.

If the “overload” indicator lights up, you should check that the wires are connected correctly and neatly. Overload can also occur due to excessive electrolyte density.

13. What to do with frosts?

The catalyst used to prepare the electrolyte makes water not freeze at relatively low temperatures. Depending on the concentration of our catalyst, the freezing temperature of the electrolyte, depending on the concentration of the catalyst, will range from -5°C to -30°C.

14. How to deal with sediment?

The appearance of sediment is due to the use of low-quality materials in the manufacture of the system or the presence of contaminants in the electrolyzer.

Recommendations from a generator manufacturer

Brown's gas can be produced by using a self-made generator. Many home craftsmen are wondering what metal should be used during the assembly process. Some people believe that only rare metals can be used.

Experts say that you can stock up on any stainless steel. Excellent results can be achieved if you use ferromagnetic steel; it does not attract debris. When choosing a metal, it is better to give preference to stainless steel, because it does not undergo oxidation.

If you are interested in the question of how long the electrode plates are ready to serve, then you should know that there is no need to change them, because they are not destroyed during operation. To prepare before welding, they must be washed well in a soapy solution, and then treated with an alcohol-containing substance similar to vodka. If you decide to make Brown's invention, which allows you to obtain gas, then you will need to run the electrolyzer for some time, replacing dirty water. You need to repeat this procedure until the water washes away the dirt. If the liquid is clean enough, the installation will not overheat.

When the electrolyzer has been assembled correctly, the plates and water will not heat up when using it. The electrolyzer should not be heated to more than 65°C. If this parameter goes outside the norm, the plates will become covered with dirt. Removal will have to be done with sandpaper, and an alternative solution is to replace the elements with new ones.

Rules for using a hydrogen generator at home

To increase the efficiency of your homemade installation, you must follow some rules. Otherwise, the cost of producing hydrogen may exceed the savings from its use in the heating system. Although one important advantage of Brown gas heating will remain in any case - the environmental friendliness of this type of fuel.

• to construct a homemade generator, it is better to use ferromagnetic stainless steel - in this case, the tubes will not oxidize and attract debris;
• You can also use plain tap water, but to improve the result it is better to use a solution of sodium hydroxide in distilled water;
• before use, the electrode plates must be washed in a soapy solution and wiped with an alcohol-containing liquid;
• Plates contaminated during operation can be cleaned with sandpaper.

The use of alternative fuels is a pressing problem for all of humanity. Gradually, scientific developments are modified and adapted to the needs of the common man. Nowadays, hydrogen generators are quite exotic devices for heating. But the trend towards the ecological use of our planet’s resources is increasingly increasing the population’s interest in new types of energy.

How to get hydrogen at home?

On the Internet you can easily find drawings and diagrams of a wide variety of homemade installations that allow you to extract Brown's gas from water. If you filter out the information garbage related to this topic, it turns out that you can get hydrogen at home in two ways. The first is to purchase a ready-made electrolyzer; these are already commercially available. One problem is that their price is too high, and the efficiency is unknown.

When buying a hydrogen generator, you need to understand that it will not be a panacea for you in terms of heating. The price of equipment and consumed electricity will be higher than simple electric heating of water, so there is no talk of payback.

As an experiment, you can make a Brown gas generator with your own hands, which allows you to release a small amount of fuel. It is unlikely to be used to heat a building, but it may well be enough to power a small burner for melting metal. First, you need to make an electrolyzer, which is a container of water in which the electrodes are immersed. The larger the surface area of ​​the electrodes, the higher the productivity of the installation. Steel plates of arbitrary size attached to a dielectric base are suitable. The working diagram of the device is shown in the figure:

Fuel from water - Brown's gas

Fuel from Water - Brown's Gas Jules Verne in his book “The Mysterious Island” (1874) wrote the following: “Water is decomposed into the primitive elements of hydrogen and oxygen, and is undoubtedly converted into electricity, which then becomes a powerful and controllable force.
Yes, my friends, I believe that water will one day be used as fuel.” Brown's gas.
This is the most advanced fuel for our vehicles. It is obtained from water (that is, hydrogen and oxygen), just like pure hydrogen, but it burns in an internal combustion engine in such a way that, depending on the adjustment, it can release oxygen into the atmosphere. The exhaust produces oxygen and water vapor (as with fuel tanks), but the oxygen here comes from the water used to produce the gas. Therefore, when Brown's gas is burned, additional oxygen is released into the atmosphere.

Thus, the use of Brown's gas helps solve the very important problem for us of reducing oxygen in the environment.

From this point of view, Brown's gas is an ideal fuel for the cars of the future. New technology for using Brown's gas

Why is Brown's gas, as a fuel, better than pure hydrogen?

Currently, the environment is experiencing serious problems, and one of them is the loss of atmospheric oxygen. Its content in the air becomes so low that in some regions it poses a threat to human existence. The normal oxygen content in the air is 21 percent, but in some regions it is several times lower! For example, in Japan in Tokyo it fell to 6-7 percent. If the oxygen content in the air reaches 5 percent, people will begin to die. In Tokyo, oxygen pillow sales points have even been installed on street corners so that people can breathe oxygen if necessary. If we don't take action, the decrease in oxygen in the air will eventually affect each of us.

Produced by electrolysis, Brown's gas can supply oxygen to the atmosphere, while other technologies either have no effect on the atmosphere (such as using pure hydrogen or fuel tanks) or pollute it (such as using fossil fuels). Therefore, we believe that this technology should be chosen to provide fuel for vehicles in the near future.

Brown's gas/HHO gas = Water decomposes into hydrogen and oxygen into electricity

Brown's gas is also called: brown gas / HHO gas / water gas / di-hydroxide / hydroxide / green gas / Klein gas / oxyhydrogen.

Each liter of water expands by 1866 liters of combustible gas.

How to make a hydrogen welding machine yourself?

Hydrogen welding is useful to any craftsman. The hydrogen cutter is not a cheap piece of equipment. In addition, commercially available machines are often unsuitable for soldering small parts, especially jewelry.

The way out of this situation is to make atomic-hydrogen welding yourself. All the parts necessary to create such a device can be easily purchased at any hardware store. So, let's look at how to do this at home.

Main capacity

Installation for welding with hydrogen.
The hydrogen welding machine operates as a result of the combustion of hydrogen, due to the dissociation of an aqueous alkali solution.

This process is carried out in a container for which a half-liter jar is perfect. It must be closed with a plastic cover with two holes made to remove contacts from the electrodes.

All terminals must be tightly sealed. Moment glue is suitable for these purposes.

Four-centimeter strips of stainless steel can be used as electrodes. For the best performance of a welding machine, the entire volume of liquid must be used.

To do this, the plates are drilled along the upper and lower edges and connected to each other with dielectric pins. Terminals are made on the resulting block: two negatives located at the edges, and a pole between them.

Each terminal is bent and fixed to the container with a bolt. The terminals from the power source will be attached to these bolts.

The container must be filled with a syringe with working fluid through the gas outlet fitting. The electrolyte is an 8-10% mixture of sodium hydroxide in distilled water. When the electrolyzer is operating, the temperature of the working liquid of the alkaline solution usually does not exceed 80 °C.

An ordinary medical needle can be used as a nozzle through which oxygen, hydrogen and flammable substances will come out.

Current source for atomic hydrogen welding

A regular 12 volt battery can be used as a power source. This option is perfect for working with metal of a fixed thickness.

Its disadvantage is the inability to control the burner flame strength, since its performance is determined by the production of hydrogen and oxygen, which depends on the current strength.

Choosing a charger for car batteries will be more preferable. To work with thin metal plates or jewelry, charging can be set to 3 volts.

Hydrogen welding can be powered with oxygen from a regular 220 V network, which allows you to use this device at home.

Exchange camera

Schematic diagram of a hydrogen welding apparatus.
To select hydrogen and oxygen supplied to the burner, another container is used - an exchange chamber.

You need to make 3 holes inside it:

• for refilling with working fluid;
• at the bottom there is a fitting for supplying working fluid to the main tank;
• fitting for supplying the gas mixture to the nozzle.

The design of the additional container must also be carefully sealed. Gases and liquids should not leak through the hydrogen seals of the hydrogen generator. This is also solved with the help of "Moment".

Making a burner

To make a burner, you can use a regular rubber hose. It is through this that hydrogen and oxygen will be transported from the exchange chamber to the nozzle. You can use a needle from a syringe or dropper as a nozzle. The latter will be a more preferable choice, since the walls of this needle are thicker.

The hose must be tightly secured to the exchange chamber fitting and the needle base. This is achieved using clamps. After completing all operations to assemble the device, you can begin testing it.

Electrolysis of the working fluid begins quickly. After just a few minutes, you can ignite the flame at the end of the nozzle. The flame is adjusted by changing the voltage on the device.

Instructions: how to make a hydrogen generator with your own hands

To manufacture a fuel cell, we will take the most advanced “dry” electrolyzer circuit using electrodes in the form of stainless steel plates. The instructions below demonstrate the process of creating a hydrogen generator from “A” to “Z”, so it is better to follow the order of actions.

Dry type fuel cell diagram

Manufacturing of the fuel cell body. The side walls of the frame are plates of hardboard or plexiglass, cut to the size of the future generator. You need to understand that the size of the device directly affects its performance, however, the costs of obtaining HHO will be higher. For the manufacture of a fuel cell, the optimal dimensions of the device will be from 150x150 mm to 250x250 mm. A hole is drilled in each of the plates for the inlet (outlet) fitting for water. In addition, drilling will be required in the side wall for gas outlet and four holes in the corners to connect the reactor elements to each other.

Using an angle grinder, electrode plates are cut from a sheet of 316L stainless steel. Their dimensions should be 10–20 mm smaller than the dimensions of the side walls. In addition, when manufacturing each part, it is necessary to leave a small contact pad in one of the corners. This will be needed to connect the negative and positive electrodes into groups before connecting them to the supply voltage. In order to obtain a sufficient amount of HHO, the stainless steel must be treated with fine sandpaper on both sides. Two holes are drilled in each of the plates: with a drill with a diameter of 6 - 7 mm - to supply water into the space between the electrodes and with a thickness of 8 - 10 mm - to remove Brown's gas. Drilling points are calculated taking into account the installation locations of the corresponding inlet and outlet pipes.

They begin assembling the generator. To do this, water supply and gas outlet fittings are installed in the hardboard walls. The places where they are connected are carefully sealed using automotive or plumbing sealant.

After this, studs are installed in one of the transparent body parts, after which they begin laying the electrodes.

The stainless steel plates are separated from the side surfaces of the reactor using O-rings, which can be made of silicone, paronite or other material

It is only important that its thickness does not exceed 1 mm. The same parts are used as spacers between the plates

During the installation process, make sure that the contact pads of the negative and positive electrodes are grouped on different sides of the generator.

After laying the last plate, a sealing ring is installed, after which the generator is closed with a second hardboard wall, and the structure itself is fastened with washers and nuts. When performing this work, be sure to ensure that the tightening is uniform and that there are no distortions between the plates.

Using polyethylene hoses, the generator is connected to a container of water and a bubbler. The contact pads of the electrodes are connected to each other in any way, after which the power wires are connected to them.

The fuel cell is supplied with voltage from a PWM generator, after which the device is configured and adjusted to the maximum HHO gas output.

To obtain Brown's gas in quantities sufficient for heating or cooking, several hydrogen generators are installed, operating in parallel.

Creating a Brown gas generator with your own hands: stages of implementation

Externally, the design of the generator is a container of water. Two tubes are placed in it. It is thanks to them that oxyhydrogen is created.

Materials for creating a generator at home:

• Stainless steel plates half a centimeter thick;
• Plexiglas sheet;
• Rubber pipes;
• Gasoline-oil-resistant rubber, 3 mm thick;
• Current source.

Stainless steel will need to be cut into rectangles. The corners will need to be cut to secure the structure with bolts. Holes with a diameter of half a centimeter should be made in each sheet, maintaining an interval of 3 cm from the bottom of the sheet. You will also need to solder a wire to send an impulse.

You will need to make several rings from rubber with an outer diameter of 20 cm. Also make two plates of plexiglass measuring 20x20 cm. The thickness of the sheets is 2 cm. Holes for bolts are made in the workpiece in advance.

After preparing the materials, assembly is performed. To begin, place the first plate. Next, install a rubber ring, which is treated with a sealed substance on both sides. Then the plate is placed again. Then the structure is tightened with bolts and plexiglass plates. The plates have holes for water supply and gas outlet. Fittings and tubes are inserted into the holes.

To prevent gas backflow, a water seal is installed on the path from the structure to the burner. It would be better to make two such fuses.

A water seal is a container containing liquid. On the side of the device, the tube is lowered into the water, and the second, which is directed to the burner, is located above the liquid level. If detonating gas gets back into the structure, the device may explode. That is why it is not recommended to use the device without a water seal.

In the electrolyzer, when electrical impulses are applied, gas begins to be produced. It moves along the first tube to the first gate. Thanks to the design of the unit, fuel backflow is eliminated. This system is maintained due to the different densities of water. The gas is then directed through the second tube to the second valve. This is a protective measure if the first shutter does not work.

Do-it-yourself method for producing Brown's gas at home

NHO gas - real know-how in heating - got its name thanks to the physicist Brown. He developed a new formula for water with certain properties. These properties were confirmed by subsequent experiments.

Brown's gas is a mixture of hydrogen and oxygen. The substance is odorless and colorless.

You can find a lot of information about getting gas at home. It is enough to build a special installation yourself. The effectiveness of such generators is confirmed by numerical positive reviews.

Parts of the gas production device:

• Chemical is represented by an electrolyzer;
• Electric – power source.

The electrolyzer has a simple design consisting of two plates or tubes immersed in water. The material for the tubes can be stainless steel. When connecting devices, different potentials should be created. This way the water will separate and the necessary gas will be released.

The electrolyzer requires current to operate. This requirement can be met with the help of water additives: soda, salt, potassium. But this is ineffective. Therefore, it is better to make a pulse generator.

How to use a hydrogen torch correctly:

First of all, always work in personal protective equipment (be sure to put a protective shield or goggles on your face), and secondly, follow fire safety rules. Thirdly, monitor the water level in the electrolyzer and the intensity of the flame.

You don’t need to ignite the flame right away, let the hydrogen displace the remaining oxygen (for me this takes about ten minutes, depending on the intensity of the release and the volume of the vessels with a water seal and fuse A, B, Fig. 1)

Be sure to keep a container of water near you - you will need it to put out the burner flame when you finish your work. To do this, you just need to point the tip of the needle with the flame under the water and thereby cut off the oxygen to the fire. ALWAYS PUT OUT THE FLAME FIRST AND THEN TURN OFF THE POWER TO THE GENERATOR - OTHERWISE AN EXPLOSION IS IMMEDIATE.

Water seal and fuse:

Pay your attention to figure No. 1 - there are two containers (I labeled them A and B), and a needle from a disposable syringe (B), all of this is connected by tubes from droppers.

You need to pour water into the first container (A), this is a water seal. It is necessary so that the explosion does not reach the electrolyzer (if it explodes, it will be like a fragmentation grenade).

Figure No. 5 – Water seal

Please note that there are two connectors in the water seal cover (I adapted all this from a medical dropper), both of them are hermetically glued into the cover using epoxy glue. One tube is long, through which hydrogen from the generator should flow under the water, gurgle, and through the second hole go through the tube to the fuse (B).

Figure No. 6 – Fuse

You can pour both water (for greater reliability) and alcohol (alcohol vapor increases the combustion temperature of the flame) into a container with a fuse.

The fuse itself is made like this: You need to make a hole in the lid with a diameter of 15 mm, and holes for the screws.

Figure No. 7 - What the holes in the lid look like

You will also need two thick washers (if necessary, you need to expand the inner diameter of the washer using a round file), two plumbing gaskets and chocolate foil or an ordinary balloon.

Figure No. 8 – Sketch of a safety valve

It is assembled quite simply; you need to drill four coaxial holes in the iron washers, lid and gaskets. First you need to solder the bolts to the top washer; this can easily be done using a powerful soldering iron and active flux.

Figure No. 9 – Washer with screws Figure No. 10 – Screws soldered to the washer

After you have soldered the screws, you need to put one rubber gasket on the washer and your valve itself. I used a thin elastic band from a burst balloon (this is much more convenient than putting on thin foil), although foil also fits quite well, at least when I tested my hydrogen torch for explosiveness, there was foil in the valve.

Figure No. 11 – Putting on the gasket and protective elastic band

Then we put on the second gasket and you can insert the protection into the holes made in the cover.

Figure No. 12 – Finished valve Figure No. 13 – Protection elements

The second washer and nuts are needed to tightly and firmly fix the protection by tightening the nuts (look at Figure No. 6).

Please understand and take note that safety rules must not be neglected, especially when working with explosive gases. And such a simple device can save you from unpleasant surprises. The protection works according to the principle “where it’s thin, it breaks”; an explosion knocks out the protective film (foil or rubber band), and the explosive force does not go into the electrolyzer; moreover, the water seal also prevents this. Take my word for it, if the electrolyzer explodes, you won’t think it’s enough :)!!!

Plate reactor

A high-performance hydrogen generator capable of ensuring the operation of a gas burner is made of stainless steel plates measuring 15 x 10 cm, quantity - from 30 to 70 pieces. Holes are drilled in them for the tightening pins, and a terminal for connecting the wire is cut out in the corner.

In addition to sheet stainless steel grade 316, you will need to buy:

• rubber 4 mm thick, resistant to alkali;
• end plates made of plexiglass or PCB;
• tie rods M10—14;
• check valve for gas welding machine;
• water filter for water seal;
• connecting pipes made of corrugated stainless steel;
• potassium hydroxide in powder form.

The plates must be assembled into a single block, isolated from each other with rubber gaskets with a cut out middle, as shown in the drawing. Tie the resulting reactor tightly with pins and connect it to the pipes with the electrolyte. The latter comes from a separate container equipped with a lid and shut-off valves.

Note. We tell you how to make a flow-through (dry) type electrolyzer. It is easier to manufacture a reactor with submersible plates - there is no need to install rubber gaskets, and the assembled unit is lowered into a sealed container with electrolyte.

Scheme of a wet-type hydrogen installation.
The subsequent assembly of the generator producing hydrogen is carried out according to the same scheme, but with differences:

1. A reservoir for preparing electrolyte is attached to the body of the device. The latter is a 7-15% solution of potassium hydroxide in water.
2. Instead of water, a so-called deoxidizing agent is poured into the “bubbler” - acetone or an inorganic solvent.
3. A check valve must be installed in front of the burner, otherwise when the hydrogen burner is turned off smoothly, the backlash will rupture the hoses and the bubbler.

To power the reactor, the easiest way is to use a welding inverter; there is no need to assemble electronic circuits. How a homemade Brown gas generator works is explained by a home craftsman in his video:

Is it profitable to produce hydrogen at home?

The answer to this question depends on the scope of application of the oxygen-hydrogen mixture. All drawings and diagrams published by various Internet resources are designed for the release of HHO gas for the following purposes:

• use hydrogen as fuel for cars;
• smokeless combustion of hydrogen in heating boilers and furnaces;
• used for gas welding work.

The main problem that negates all the advantages of hydrogen fuel: the cost of electricity to release the pure substance exceeds the amount of energy obtained from its combustion. Whatever adherents of utopian theories may claim, the maximum efficiency of the electrolyzer reaches 50%. This means that for 1 kW of heat received, 2 kW of electricity is consumed. The benefit is zero, even negative.

Let's remember what we wrote in the first section. Hydrogen is a very active element and reacts with oxygen on its own, releasing a lot of heat. When trying to split a stable water molecule, we cannot apply energy directly to the atoms. The splitting is carried out using electricity, half of which is dissipated to heat the electrodes, water, transformer windings, and so on.

Important background information. The specific heat of combustion of hydrogen is three times higher than that of methane, but by mass. If we compare them by volume, then when burning 1 m³ of hydrogen, only 3.6 kW of thermal energy will be released versus 11 kW for methane. After all, hydrogen is the lightest chemical element.

Now let's consider detonating gas obtained by electrolysis in a homemade hydrogen generator as fuel for the above needs:

1. The final installation price, low productivity and efficiency make it extremely unprofitable to burn hydrogen for heating a private home. Rather than “winding” the meter with an electrolyzer, it is easier to install any of the electric boilers - heating element, induction or electrode.
2. To replace 1 liter of gasoline for a car, you will need 4766 liters of pure hydrogen or 7150 liters of detonating gas, a third of which is oxygen. The most lying inventor on the Internet has not yet made an electrolyzer capable of providing such productivity.

   

3. A gas welding machine that burns hydrogen is more compact and lighter than cylinders with acetylene, propane and oxygen. Plus, the flame temperature of up to 3000 °C allows you to work with any metals; the cost of obtaining fuel does not play a special role here.

For reference. To burn hydrogen in a heating boiler, you will have to thoroughly redesign the design, since a hydrogen burner can melt any steel.

Design and principle of operation of a hydrogen generator

The factory hydrogen generator is an impressive unit

Using hydrogen as a fuel for heating a country house is beneficial not only because of its high calorific value, but also because no harmful substances are released during its combustion. As everyone remembers from a school chemistry course, when two hydrogen atoms (chemical formula H2 - Hidrogenium) are oxidized by one oxygen atom, a water molecule is formed. This produces three times more heat than the combustion of natural gas. We can say that hydrogen has no equal among other energy sources, since its reserves on Earth are inexhaustible - 2/3 of the world’s oceans consists of the chemical element H2, and in the entire Universe this gas, along with helium, is the main “building material”. There's just one problem - to get pure H2 you need to split water into its component parts, and this is not easy to do. Scientists have been looking for a way to extract hydrogen for many years and settled on electrolysis.

Laboratory electrolyzer operation diagram

This method of producing volatile gas involves placing two metal plates connected to a high voltage source in water at a short distance from each other. When power is applied, the high electrical potential literally tears the water molecule apart, releasing two hydrogen (HH) atoms and one oxygen (O) atom. The released gas was named after the physicist Yu. Brown. Its formula is HHO, and its calorific value is 121 MJ/kg. Brown's gas burns with an open flame and does not produce any harmful substances. The main advantage of this substance is that a regular boiler running on propane or methane is suitable for its use. Let us only note that hydrogen in combination with oxygen forms an explosive mixture, so additional precautions will be required.

Installation diagram for producing Brown's gas

The generator, designed to produce Brown's gas in large quantities, contains several cells, each of which contains many pairs of electrode plates. They are installed in a sealed container, which is equipped with a gas outlet, terminals for connecting power and a neck for filling water. In addition, the installation is equipped with a safety valve and a water seal. Thanks to them, the possibility of backfire spreading is eliminated. Hydrogen burns only at the exit of the burner, and does not ignite in all directions. A multiple increase in the usable area of ​​the installation makes it possible to extract the flammable substance in quantities sufficient for various purposes, including heating residential premises. But doing this using a traditional electrolyzer will be unprofitable. Simply put, if the electricity spent on hydrogen production is directly used to heat a house, then it will be much more profitable than heating a boiler with hydrogen.

Stanley Meyer hydrogen fuel cell

The American scientist Stanley Meyer found a way out of this situation. His installation did not use powerful electrical potential, but currents of a certain frequency. The invention of the great physicist consisted in the fact that a water molecule swayed in time with changing electrical impulses and entered into resonance, which reached a force sufficient to split it into its constituent atoms. Such an effect required tens of times less current than when operating a conventional electrolysis machine.

Video: Stanley Meyer Fuel Cell

For his invention, which could free humanity from the bondage of oil magnates, Stanley Meyer was killed, and the works of his many years of research disappeared to God knows where. Nevertheless, some of the scientist’s notes have been preserved, on the basis of which inventors in many countries around the world are trying to build similar installations. And I must say, not without success.

Advantages of Brown's gas as an energy source

• Water, from which HHO is obtained, is one of the most common substances on our planet.
• When this type of fuel burns, it produces water vapor, which can be condensed back into liquid and reused as a raw material.
• During the combustion of detonating gas, no by-products are formed except water. We can say that there is no more environmentally friendly type of fuel than Brown's gas.
• When operating a hydrogen heating system, water vapor is released in an amount sufficient to maintain the humidity in the room at a comfortable level.

Application area

Today, an electrolyzer is as common a device as an acetylene generator or a plasma cutter. Initially, hydrogen generators were used by welders, since carrying a unit weighing only a few kilograms was much easier than moving huge oxygen and acetylene cylinders. At the same time, the high energy intensity of the units was not of decisive importance - everything was determined by convenience and practicality. In recent years, the use of Brown's gas has gone beyond the usual concepts of hydrogen as a fuel for gas welding machines. In the future, the possibilities of the technology are very wide, since the use of HHO has many advantages.

• Reducing fuel consumption in vehicles. Existing automotive hydrogen generators allow the use of HHO as an additive to traditional gasoline, diesel or gas. Due to more complete combustion of the fuel mixture, a 20–25% reduction in hydrocarbon consumption can be achieved.
• Fuel savings at thermal power plants using gas, coal or fuel oil.
• Reducing toxicity and increasing the efficiency of old boiler houses.
• Multiple reductions in the cost of heating residential buildings due to the complete or partial replacement of traditional fuels with Brown gas.
• Using portable HHO production units for domestic needs - cooking, obtaining warm water, etc.
• Development of fundamentally new, powerful and environmentally friendly power plants.

A hydrogen generator built using S. Meyer’s “Water Fuel Cell Technology” (that’s what his treatise was called) can be bought - many companies in the USA, China, Bulgaria and other countries are engaged in their production. We propose to make a hydrogen generator yourself.

Safety precautions and operating features

A hydrogen heating boiler must be operated correctly.

When using it, adhere to the following rules:

• You cannot upgrade or modify hydrogen heating equipment yourself. This increases the likelihood of hydrogen leakage. When it interacts with air, an explosive situation is created.
• Install temperature sensors inside the heat exchanger. This will allow you to control the degree of water heating. Check the temperature periodically to ensure that the coolant does not overheat.
• Do not operate heating equipment in modes and conditions that are not provided by the manufacturer. This could lead to an unwanted chain reaction.
• Install shut-off valves on the burner device and connect it to the temperature sensor. This will allow the boiler to be cooled if necessary.
• If the gas pressure in the combustion chamber increases critically, then it is necessary to find out the reason for this increase and take measures to stabilize the operation.
• Monitor the water supply and periodically change the electrolyte solution.

Important! With proper and careful operation, hydrogen heating equipment will last up to 30 years, twice the warranty period.
