Buleryan with a water circuit - operating principle and installation features

was founded in 1993. Previously it was called "Laotherm", and then - "Breneran". Today it is engaged in the production of stoves and fireplaces. Additionally, baths and gas generating devices are manufactured. All products of this brand undergo strict testing. The result is a very high quality product that comes with a great guarantee.

The appearance of Buleryan stoves with a water circuit

The first Buleryan stove with a water circuit received good reviews. This was largely due to the fact that it could easily heat a room with a total area of up to 100 cubic meters. m. They were most often used in large enterprises and factories.

Company specialists note that the efficiency of such devices sometimes reaches 70%. The high level with the water circuit should also be taken into account. Some models of this brand are capable of working continuously for more than 6 hours.

Design and operating principle

In order to understand how the Buleryan stove with a water circuit is designed and works, it is necessary to understand the principle of operation of the original stove. It originally appeared in Canada. The purpose of its construction is to create a highly efficient unit capable of warming up rooms in a matter of minutes in harsh climates. This is how the Buleryan stove was born, initially without a water circuit. It is a kind of long-burning pyrolysis stove with a built-in convector.

The Buleryan stove without a water circuit is a barrel-shaped structure with pipes sticking out at the bottom and top. These pipes go around the combustion chamber on all sides, forming a productive convector capable of passing through up to several cubic meters of air per hour. Within half an hour after the initial ignition, the room becomes noticeably warmer. In addition to the air convector, the design of the unit contains:

Even if this type of stove is not particularly elegant, it copes with its direct responsibilities perfectly.

An impressive combustion chamber - a large amount of firewood is placed in it, which guarantees long-lasting combustion;
Internal partition for the formation of an afterburning chamber - here the afterburning of pyrolysis products occurs;
Loading door with a throttle valve - firewood is loaded through it and ash is unloaded;
Chimney - combustion products are removed through it.

Buleryan wood stoves with water circuits can be equipped with economizers. In them, the final heat is removed and gaseous products that are not burned in the unit itself are accumulated and burned.

In models with water circuits, economizers are not particularly needed, since heating here is carried out using radiators.

The operating principle of the Buleryan stove is very simple. Since it is a very ordinary pyrolysis unit, fuel combustion occurs with minimal access of oxygen to the main chamber - the throttle valve on the loading door is responsible for this. The maximum heat release is produced in the afterburning chamber, where the combustion products formed in the first chamber burn out. The resulting heat is released into heated rooms.

If a conventional stove like a potbelly stove heats due to thermal radiation from its body, then Buleryan without a water circuit heats due to convection. Pipes of sufficiently large diameter are used here, completely covering the combustion chamber. The air passing through them is heated to a temperature of +100-120 degrees and enters the rooms. This scheme ensures very fast heating of the premises.

Features of Buleryan stoves without water circuits:

It is the special metal pipes surrounding the combustion chamber that determine such an unusual appearance and high efficiency of the furnace.

High efficiency - it reaches 80%;
Possibility of heating several rooms at once - for this purpose, air ducts are organized with distribution throughout the rooms;
Original design with interesting industrial design;
Prompt heating due to the powerful convection effect;
Low housing temperature during operation ensures safe operation.

Buleryan stoves are manufactured by many manufacturers. They have minor structural differences, but in general they are designed approximately the same.

Furnace design with a water circuit

Furnaces with a water circuit operate exclusively in rooms with an open heating system. It should also be taken into account that the increase in coolant occurs by itself. In general, a furnace with a water circuit consists of two chambers. At the bottom of the device there is a gasification department. The afterburning chamber, in turn, is located on top.

Additionally, there are two regulators that control the furnace power. Heat exchange pipes are located above the gasification chamber. They are connected to the secondary section. In this case, on the side panel there is a chimney pipe with a controller. Below is the double rear wall of the oven. The primary chamber of the device is connected to the ash pan. In this case, the furnace ash is connected to the power control knob. There is also a special loading door. An injector is located behind the front wall of the furnace.

Principle of operation

This oven operates according to the well-known law of physics. The basic principle is that hot steam tends to rise, while cold steam goes down. Thanks to this, even small ovens equipped with a water jacket are able to provide heating up to 5 cubic meters. m. air .
In this case, the equipment does not heat up. That is, oxygen burnout in the room is excluded. Experts consider Buleryan to be one of the stoves that are economical, since by using it in your home, you can reduce fuel costs. This is ensured due to the presence of a special afterburning chamber in its design. It burns all the gas that was formed during the combustion process. The casing acts as a heat exchanger in the design of such a furnace. Inside the casing you can find at least 6 pipes that are adjacent to the ceiling chamber. This ensures better heat transfer in water.

The coolant is supplied to the top point of the entire system. Then it goes directly to the radiators, and from them again to the oven. It is there that the tap is located, through which the coolant is drained. This simple principle of operation of this stove, equipped with a water circuit, ensures rapid heating of a room of any size without drying out the oxygen.

Model "Aqua-Breneran"

This model “Buleryan Aqua” has not yet received reviews from customers, because it is not yet very well known. It was created for heating homes and industrial facilities. Its peculiarity is the use of different types of solid fuel. Most often, such stoves are loaded with coal or ordinary firewood.

At the same time, on one tab it is capable of continuously working for more than 7 hours, which is why the Aqua-Breneran (Buleryan) boiler received positive reviews from specialists.

Main disadvantages

If you decide to install a Buleryan stove in the garage, experts recommend reading reviews about it. Among them, we should highlight the ability of the equipment to operate exclusively using firewood. It should also be mentioned that a large volume of generator gases does not burn, flying out into the chimney.

The firewood does not burn completely, the stove produces smoke, and the soot goes into the chimney pipe. This entails the need to extend the pipe 3 m from the height of the furnace. All these are additional costs, to which must be added the fact that the pipe needs thermal insulation. It does not matter whether the structure is made of metal or brick.

Reviews of the Buleryan long-burning stove also indicate that condensation from water, soot and tar accumulates in the chimney during operation. This happens because the fuel does not burn completely. The pipe cokes, and during kindling an unpleasant odor is formed, which is especially important after a long period of inactivity.

Consumers point out another disadvantage, which is that dust burns on the hot metal of the structure. This does not improve the atmosphere of the premises. The operating principle of the heating device leads to such consequences: the design is designed for heat transfer from the surface. It is not so easy to ensure long combustion and maximum heat transfer on one tab. To do this, you will have to master the skills of adjusting the damper. Reviews of the Buleryan dacha stove indicate that smoldering combustion causes many side effects.

Consumer reviews about the Buleryan Country stove (type 00)

“Buleryan Country” has good reviews. Most buyers loved this model for its versatility. You can easily load firewood and coal into it. At the same time, this stove has good performance and is capable of heating a room with a volume of up to 100 cubic meters. m.

Its height is 700 mm, width - 480 mm, and depth - 685 mm. In this case, the total weight of the stove is 65 kg. The diameter of the chimney, in turn, is quite significant and amounts to as much as 120 mm. The oven body itself is made of durable steel. In addition to firewood and coal, sawdust, briquettes, and peat can be loaded into the chamber. Taking this into account, this Buleryan stove generally receives good reviews from customers.

Experts' opinion about the Buleryan Country stove (type 00)

This Buleryan stove has different reviews from experts. As some experts note, the body of this model is quite durable. In this furnace, manufacturers used 08KP steel. Additionally, many are pleased that the outlet pipe comes without ovalization. There are also no narrowing areas on it. In this case, the pipe diameter is 57 mm, which ensures high productivity.

Experts also noted the high quality of welding on the furnace. According to the manufacturers, all parts of the device were made on a special plasma cutting machine. If you load firewood or coal into the oven, it will last for about 7 hours. The firebox of the device is completely closed. The heat exchanger is also made of steel. In general, the model is considered inexpensive, which is why all the stoves in the Buleryan 00 series have mostly positive reviews.

Stove "Buleryan Classic" (type 00)

“Buleryan Classic” has good reviews because it is very similar to the previous model. Its power is at a fairly high level and amounts to 6 kW. At the same time, the stove is capable of heating a house with a total volume of up to 100 cubic meters. m. Also, many are pleased with the fact that you can order it from the manufacturer in absolutely any color.

Briquettes and firewood are mainly used to load the stove. However, some people prefer only wood waste. Be that as it may, the efficiency of this model is at the level of 75%. This is largely due to the use of two-phase fuel combustion. At first, the fuel simply smolders, and gases are released. In the second stage, the gases are completely removed. All this makes it possible to download for about 8 hours. The furnace casing is made of stainless steel. Additionally, buyers noted that the kit comes with a convenient stand.

Buleryan stove-boiler is a leader among solid fuel convection heaters

Heating a home or any other room is a very important task, especially in winter. Heating must be stable, safe and affordable.

There are many heating units, but one of the best options is the Buleryan convection heater.

The Buleryan stove-boiler is a solid fuel heat generator for air heating of a room.

Buleryan furnace-boiler: design

The boiler design is as follows:

A cylindrical body consisting of two combustion chambers, made of steel or cast iron.
The lower combustion chamber is filled with fuel.
The upper combustion chamber is needed to burn the fuel.
The air heat exchanger is made in the form of curved pipes passing through the combustion chamber. The unit operates on the principle of natural convection - hot air rises, and a flow of cold air comes in its place.
Fuel loading door.
Damper for temperature regulation.

Natural convection and forced injection

Air convection occurs due to temperature differences. The boiler generates a constant flow of hot air directed upward. This flow displaces cold air, which enters the heat exchanger tubes. This is how constant air circulation occurs in the room.

Forced injection is carried out by installing blower fans. But this method requires additional costs for equipment and the unit becomes energy dependent.

Operating principle of the Buleryan boiler

The main fuel for the boiler is any wood materials: firewood, briquettes, peat, pellets, cardboard and others.

The Buleryan boiler has a high efficiency factor (efficiency) of 85%. This figure is achieved due to efficient combustion of fuel.

Fast warm-up Fuel is loaded into the lower combustion chamber and ignited - this is the fast warm-up mode. The air in the room heats up in 15 minutes.
Gasification After sufficient temperature has been created in the firebox, the boiler switches to gasification mode. This means that combustion stops in the lower firebox, and the fuel simply smolders. As a result of smoldering, pyrolysis gas is released, which accumulates in the second combustion chamber and ignites there, releasing thermal energy.

Temperature

A special air damper is provided to regulate the air temperature. Closing it reduces the intensity of combustion, so the air temperature decreases. This process is controlled manually or automatically.

To set and maintain a constant temperature regime, an automatic system is provided, consisting of a temperature sensor and a drive mechanism that acts on the damper.

Advantages of Buleryan boilers:

Efficient operation of the unit - efficiency 85%.
Cheap and available fuel.
Energy independence.
Easy to maintain.
Large selection of capacities.
Simple installation process.

Disadvantages of Buleryan boilers:

They only run on wood fuel.
During operation, some areas of the furnace heat up to 1200C.
Remains of combustion products in the air.

Types of boilers Buleryan

Buleryan heating convection boilers come in six models of varying power, allowing you to heat rooms from 100 m3 to 1100 m3. Buleryan boilers began to be used in liquid coolant systems.

Depending on the purpose, Buleryan boilers are:

Coolant circuit

The heat exchanger for liquid coolant is a tubular jacket that covers 70% of the combustion chamber of the boiler, which makes it possible to heat the coolant quite efficiently. However, the use of Buleryan boilers is permissible only in water heating systems with natural coolant circulation.

Expert assessment of the Buleryan Classic stove (type 00)

This Buleryan stove with a water circuit received good reviews from most experts. As experts note, its dimensions are quite acceptable for such a high power device. The height of the model is 700 m, width - 480 mm, and depth - 685 mm. The total weight of the furnace with a water circuit is 65 kg. In this case, the chimney diameter is 120 mm.

Additionally, experts assessed the quality of the loading chamber. The handles are quite tight and the door is easy to open. Also, many positively characterized the mechanism for adjusting the power of the furnace. During heating, everything can be easily adjusted and at the same time monitor the internal chamber. All pipes have the correct ovalization and are manufactured without microdefects using special equipment.

The seams along the edges of the joints are well smoothed, which indicates high quality welding. Additionally, experts noted the convenience of loading fuel. The diameter of the entrance chamber is quite large, and this allows you to quickly make masonry.

Tips and rules of operation

For the Buleryan heating system, it is necessary to comply with operating conditions, which makes it possible to increase the efficiency of the installation and extend its service life. Comments from numerous stove users show that the most pressing questions are:

measures to prevent freezing of the coolant when the heating system is turned off;
reasons for low productivity;
rules and features of the firebox;
Is it possible to install the structure outdoors?

How to prevent the circuit from freezing?

When operating the furnace, care should be taken to ensure that the coolant does not freeze. For this purpose, the boilers have a built-in 1 kW heating element. The system is equipped with a sensor that constantly monitors the coolant temperature and turns on additional heating when it drops to a minimum level.

A method of protection is also the complete drainage of water when the system is turned off. In this case, the pipes and housing will withstand frosts down to -50 degrees.

Why does Buleryan start to heat up poorly?

Why can water boilers not heat a room well? The reasons may be as follows:

incorrect installation/connection (insufficient height of the chimney pipe, poor gas outlet);
improper installation of the stove with a violation of the height (a distance from the floor of 40-50 cm is allowed, in other cases the performance of the system decreases);
the wood-burning stove has too low power (the actual power is 10% lower than that indicated in the documentation, which is due to the peculiarities of the installation);
too many connected radiators.

Firebox features

The Buleryan boiler with a water circuit is heated using the smoldering mode; wood chips, firewood, and paper are used for ignition. Intense combustion is observed only in the first half hour, then the stove should switch to normal mode.

Attention: The stove should not operate at its maximum, the thermal conductivity of the body is limited and the heat will go to nowhere. The efficiency of the design during strong acceleration will be extremely low; this is a waste of fuel.

The principle of kindling Bullerjan will be as follows:

the gasifier and special regulator open completely;
light a fire (it is best to use paper and small wood chips);
after the fire ignites, the chamber is filled to 80%;
it is necessary to heat until the sensor shows a value of 180-200 degrees (the heating time is no more than 20-30 minutes);
then the gasifier must be closed at 45 degrees.

Wood fuel is used for the firebox; logs with a size corresponding to the length of the chamber that are not split into pieces are best suited. The firebox door must close tightly; no gaps are allowed. The ash of the heating furnace is not removed; it remains in the chamber throughout its operation.

Outdoor installation

Is it possible to install Buleryan water boilers outdoors? Theoretically, it is allowed, but in practice it is not recommended, since the presence of a “water” jacket will greatly limit the possibility of the device under such conditions.

At the same time, the blower has a good diameter. Experts also highlighted the design of the rear panel, which consists of two plates. Considering all of the above, Buleryan heating receives only good reviews from experts.

How does the Buleryan stove work?

The Buleryan stove is often compared to a potbelly stove and a regular long-burning wood stove. We can say that the device took elements from both.

The operation of the oven is based on the principle of convection. Pipes for heat exchange are connected to the volumetric secondary chamber, in which the process of burning wood occurs. The principle of their operation is very simple. Cold air enters the pipe at the base of the Buleryan stove, and then comes out already heated at the top of the structure.

The furnace body can be of two shapes. For small rooms, cylindrical Buleryan stoves are most often made. For a large heating area, the stove takes on a teardrop shape. Pipes are placed on the outside of the structure. To ensure maximum heat transfer, they are soldered into the structure and protrude by only one third.

Operating principle of the Buleryan stove

The furnace firebox consists of three parts. A grate or fire-resistant mesh is placed at the bottom of the firebox. They can be made of cast iron or steel with a thickness of at least 4 millimeters. There is a special compartment at the top of the firebox. It is obtained thanks to a partition, for the manufacture of which a steel sheet is used. This compartment is also called the secondary chamber. In it, the combustion of gases occurs, which are released during the burning of wood. Combustion of fuel in the furnace itself is not complete. The released combustion products pass into the chimney. The length of the chimney is about 1 meter. Due to this part of the furnace, the combustion process becomes slower, and the combustion products cool down. The chimney is made curved and contains an economizer. Thanks to this device, secondary combustion of gases occurs. This stove structure increases heat transfer by 20% compared to other stoves.

The combustion process of wood is regulated using a damper. The damper is a damper near the exit from the firebox that regulates the intensity of the draft. It is attached to the pipe using a special metal rod. On the door, by changing the position of the gate, you can regulate the intensity of the oven.

Scheme of the Buleryan furnace

The Buleryan stove is enough to heat a room of 100 m3. This will take no more than 3 hours. Large designs of the Buleryan stove are suitable even for heating large rooms, up to 400 m3. Not every oven can cope with such a task.

Keeping warm is also easy. Buleryan is an economical stove that requires adding firewood only twice a day.

Stove "Buleryan Classic" (type 01)

Consumers generally appreciated the ease of use of this stove. You can freely put up to 6 kg of firewood into the loading chamber. This should be enough to heat a room of 80 square meters for 9 hours. m. You should also take into account the high efficiency. Overall, this model is very economical. If you use coal, then one load is enough to heat the room for 12 hours. Also, this Buleryan stove receives good user reviews because it has a durable design.

Installation of the Buleryan stove

The oven is mobile. Installation and dismantling of the product is not difficult. Installation does not require specialized education.

A person with minimal technical knowledge can perform the work.

Fire safety standards for installation

Buleryan is a furnace, some surfaces of which can heat up to high temperatures. This should be taken into account and fire safety standards must be observed during installation.

The stove is installed:

on a non-combustible base. If the floor in a room is susceptible to fire when exposed to high temperatures, it is necessary to arrange a specialized area on which the product will be installed;
distance to walls. Before installing Buleryan, you need to choose the right installation location. The stove heats the room by heating air masses. When choosing a location, you need to take into account the distance from the stove surfaces to the walls.

This parameter depends on the material from which the vertical surfaces are made. For wooden, unplastered walls, a minimum distance of 1 m is required. for concrete surfaces this figure is reduced.

Is a foundation needed for Buleryan

The location and method of installing the boiler differs depending on the preferences of the owner of the room and the materials from which the surfaces are made.

At the installation site, it is necessary to equip a specialized platform made of non-combustible material. Typically, a sheet of metal is used or a foundation is fabricated.

Some experts mount the stove on a stand made of a profile pipe.

The foundation is made with a height of 10–30 cm. The material for arranging the site can be brick, cinder block, concrete, etc.

The overall dimensions of the foundation must exceed the dimensions of the boiler. The protrusion located under the fuel loading hatch should protect the floor covering from sparks and heat.

Possible mistakes

When installing the Buleryan stove with your own hands, it is important to maintain all the necessary distances to vertical surfaces. This will ensure fire safety and free access to the boiler for maintenance.

Experts' opinion about the Buleryan Classic stove (type 01)

In general, experts consider this model comfortable and powerful. At the same time, it has all the advantages that are displayed in previous models. The secondary camera of the device is quite durable. The thickness of the metal in this place reaches 4 mm. Experts also noted the convenience of the loading compartment. Its door fits tightly and provides a good seal.

The front wall is quite strong and protects the injector well. All power controls are easy to adjust. The chimney handle, in turn, is securely fastened. Additionally, many experts positively noted the operation of the blower, which is hidden behind the rear panel. In general, this model can be characterized as a practical and powerful device for heating large houses.

Functional Features

A heating device with a water circuit operates on the principle of convection, but with one significant addition: instead of air, a coolant liquid is used. This prevents oxygen from penetrating through the partitions. The effectiveness of such equipment is obvious due to the following features:

Inside the casing there is a combustion chamber, which is tightly fitted with pipes containing liquid. Due to this fit, heat is transferred much faster. The number of rolled metal products can vary from 6 to 12 pieces.
The required pressure in the system is provided by a special pressure manifold, which raises the coolant to a height of up to 8 m.
Natural circulation in the heating system is ensured by heating the liquid substance used to transfer energy.
The principle of operation of the furnace is to raise the coolant to the maximum height, and then distribute it among the batteries. Next, the liquid substance used to transfer thermal energy is returned to the furnace via the return line.
Increased device performance and reduced fuel consumption are achieved due to the gas generation process used. After burning wood, the resulting gas is burned in a separate chamber.
The drain valve is installed on the return line. Circular equipment is also installed at this location, which can significantly increase the efficiency of the entire system.
