Initially, this type of stove was intended for Canadian lumberjacks. The unit was made specifically for their working conditions, namely frequent moving in winter from one place to another. Therefore, the main requirements for the design were the following:
- Safety and effectiveness. The stove had to heat the room in a short time.
- Compliance with the conditions for quick and easy installation of the structure, the absence of complex settings and adjustment processes.
- Eliminating the possibility of burns through the choice of material and proper execution of the furnace lining.
- Impossibility of carbon monoxide entering the room.
- Relatively light weight of the entire structure.
Before we begin to describe the design of the unit, we advise you to pay attention to the drawings:
Now we move on to studying the structure of the Buleryan furnace. The compact model has a cylindrical body. The unit for heating a large room is made in the form of a drop (in cross section).
In most cases, the pipes are located in the housing, protruding beyond its boundaries by only a third. In this case, the products are curved along a sinusoid.
This form allows you to create optimal conditions heat transfer, when the pipes located below receive cold air. Moving through the channels, the flow gradually warms up and becomes hot at the outlet.
When wood is actively burning, the air temperature can rise to 120 degrees or more. In one minute, 4-6 m³ is pumped, which is a good indicator confirming the process of quickly warming up the room.
As for the firebox, it consists of three components. The upper and lower parts of the device for burning flammable substances are separated by one quarter. Cast iron grates or a steel grate with a thickness of more than 4 mm are installed below. The upper part of the firebox is separated by a steel sheet in which holes are made. The partition is installed horizontally and does not reach the door slightly. This element serves as a secondary chamber where gases released during fuel combustion burn out. In this case, air comes from the firebox and passes through the holes in the partition. Thus, the combustion of raw materials is incomplete. The remaining part of the gases burns out in the channel. 
The wide-format door is manufactured with an airtight seal. There is also a pipe with a built-in rotary throttle, which plays the role of a blower. By adjusting the position, the limiter affects the intensity of fuel combustion. Sometimes manufacturers provide a graduated scale for the throttle.
The main feature of the Buleryan wood-burning stove is that part of the fuel combustion process is transferred to the pipes. The remaining gases move from the upper structure of the firebox to the horizontal plane of the chimney, equal to 1 m. Such a section is mandatory for a “Buleryan” type stove, since it is here that the combustion of gases is inhibited, allowing them to cool slightly. After the horizontal section, the smoke channel is directed upward. At the turning point wood stove"Buleryan" installation is provided special device– an economizer that completes the afterburning of pyrolysis gases.
Thanks to this device, the efficiency of the furnace structure reaches 80%, and without it - 60% (which is also considered a good result).
In a section of the chimney 15-30 cm long, the secondary combustion process of gas residues takes place. In this case, combustion occurs periodically, flaring up and dying out. To achieve this effect, the pipe must be well insulated. For these purposes, any thermal insulation material, able to withstand high temperatures, for example, basalt wool or mineral cardboard. The number of layers depends on technical characteristics the material used.
Gases that have not completely cooled after passing through a horizontal section of the pipe enter a previously insulated area, where, thanks to the thermal insulation, they accumulate large quantity thermal energy. As a result, the temperature of the gas residues rises and they flare up again. The ignited mixture of hydrocarbons begins to increase in volume, but the limited space leads to clogging of the pipe lumen. A gas plug forms. The substance burns out, cools and dissolves.
Then the process is repeated. Its intensity and frequency depend on the quality of the fuel and the throttle position. It should be noted that the Buleryan stove automatically adjusts to the specified parameters without requiring adjustment.
The next component of the design is the gate valve. It is installed at the exit from the firebox and is needed to adjust the draft intensity. The damper is made with a diameter 20% smaller than that of the chimney. A part is cut out on the damper - a sector equal to a quarter of the circle. This plug is welded onto a metal rod and attached to the pipe. The gate and throttle on the door allow you to select the combustion mode. The operation of the furnace directly depends on the fuel raw material and the position of the gate with the throttle.
Below is a visualization of everything described above, namely the “Buleryan” diagram:
Why did the stove start smoking?
For safe operation of the stove, it is necessary to carefully prepare the base, comply with all requirements for the installation of the chimney, and ensure regular maintenance of the structure. While using the stove, owners should pay attention to the operation of the device and the appearance of certain signs indicating a malfunction of the equipment.
Below are a few typical reasons why a stove may smoke:
- Insufficient insulation of the channel. The convection type of the unit imposes requirements on the smoke exhaust system. It is recommended to use ceramic or sandwich pipes.
- Accumulation of tar on the walls of the chimney. It must be cleaned at least once a year.
- Low channel height. Its minimum value is 3 m. It is important to correctly calculate the height between the roof ridge and the umbrella.
If you meet all these conditions and regularly carry out maintenance work on the structure, you will be able to avoid problems with poor draft and smoke.
Bottom line
We hope this article was able to convince you of the originality and feasibility of the Buleryan design, especially since many have already been able to verify this in practice. A similar wood-burning stove, reviews of which can be found on forums, is a fairly popular and effective type of equipment.
What is buleryan, as it turns out - it’s a stove long burning, air-convection heating. Sometimes using gas afterburning technologies. Happens to the boiler function, and sometimes to the cooking surface. Frankly speaking, from a subjective, but not devoid of common sense, view, this type of stoves is not designed for indoors permanent residence. This stove will heat the air in the room quite efficiently and quickly. This could be a guest house, workshop, garage, office or admin. premises, greenhouse, etc..
The main advantage is that the entire volume of air will quickly reach the desired temperature. However this design the furnace has no thermal inertia. At the dacha in winter or in hunting lodge in the mountains, such a property is not of great importance. In a permanent building, a powerful, massive coolant provides an even, correct microclimate without jumps and changes. Which has a positive effect both on the health of the owners and on the integrity and safety of the house itself, its components and designs. True, nowadays, new technologies and ideas make it possible to implement almost any solution. And with a conscious approach and understanding of some of the subtleties, such a heating device will fulfill any whim of the owner. In addition, heating using exclusively air convection will allow you to save a lot on materials and speed up the heating installation.
Operating principle of the furnace
It is worth knowing why “Buleryan” is interesting, the operating principle of which we will now consider. You might think it's simple metal barrel, with built-in pipes.
Buller or bullerjan, uses the now again popular fuel saving technology. Namely, pyrolysis.
True, how correct it would be to call a buller pyrolysis is debatable. Often, a buller is called pyrolysis, although this is only partly true. Since in pyrolysis boilers, primary air usually passes through the fuel, from top to bottom. The draft is forced and, accordingly, the design and equipment are different. In itself, this is the process of wood decomposition under the influence of temperature. For volatile hydrocarbons, carbon monoxide and charcoal.
Video: Buleryan power calculation
Pyrolysis devices can be considered devices that burn pyrolysis gas in a secondary chamber. An isothermal process occurs in the primary chamber, with the release of heat and gases. Here we have similar processes, albeit not ideally executed. Therefore, I might have called our experimental subject a pyrolysis boiler, but I wouldn’t guarantee it one hundred percent and wouldn’t argue. Since combustion processes similar to those occurring in the buller partly occur in simple ovens. It is located in the middle, between the potbelly stove and absolutely pyrolysis-oriented devices. The air is heated thanks to an impressive battery of pipe convectors. In which the air quickly warms up and circulates. Moreover, the room air is well mixed due to the speed with which it escapes from the exchangers.
Drawing
Now, apparently, it’s worth clarifying what this wonderful barrel, hugged by pipes, consists of. Buleryan, the drawing of which, nevertheless, folk craftsmen were able to recreate, is not so complicated. This technologically advanced “potbelly stove” incorporates some elements of different stoves: the main firebox, extra space, for afterburning gases formed during the primary combustion (or rather, combustion-smoldering) of fuel.
Next, the main elements include the main heat exchange elements - arc-curved pipe sections. The main process of convection occurs in them. Pipes, as a rule, are immersed in the firebox with two-thirds of their diameter. At the same time, they are part of the walls of the firebox and are in direct contact with the heat of the flame. There are options for fireboxes with a grate, when they want to add protection against burnout to the walls of the heat exchanger.
The upper part of the firebox, separated by a horizontal plate from the lower part, allows the gases to be burned when additional heated air enters there. It comes through injectors. The location and place of insertion into the furnace may vary slightly.
The classic version of the buller has a door with a blower, equipped with an air supply regulator, a throttle and an ash pan. Options can be with conditional graduation of air supply, fire-resistant glass, eyes for controlling gas afterburning and other differences. At the outlet, the chimney is necessarily equipped with a damper with a guaranteed open sector of a quarter section. This ensures reliable removal of carbon monoxide, except in cases of obvious emergency.
Buleryan in section
Chimney pipes must be equipped with thermal insulation, as this is decisively important for this type of stove. Original products, originally from Canada, are equipped with an economizer. It is mounted immediately after the first bend of the chimney, on its vertical part, and also participates in the afterburning of gas generation and oxidation products. Quite importantly, this increases efficiency and helps gases leave the chimney faster. Not to be confused with additional heat exchangers that are installed on the chimney to heat water or simply for additional heat-calories, in reserve. There are also so-called heat accumulators. The chimney, or rather its vertical part, must be of sufficient length, depending on your structure. On average it is about five meters. But you should not install the chimney lower; this length will not provide the necessary draft.
“Buleryan” drawing
The thickness is usually at least five millimeters. This is done when the pipes are already attached to each other, forming the skeleton of the furnace, and the partitions, if any, are welded in. Air input through injectors can be provided through the first pair of convectors, or through the front wall. Equipping them with dosing devices, like a simple air tap. The main thing is to supply a portion of fresh air to the “entrance” of the pyrolysis gases, into the afterburning chamber. Next, the design is equipped back wall, with outlet, for chimney. You can equip it with a container for heating water. Therefore, when assembling Buleryan with your own hands, the drawings will have to be corrected. It is in this place that such a “gadget” will interfere least of all, in contrast to similar solutions directly on the chimney. Which it is advisable to make somewhat larger in cross-section than at the entrance to the blower.
Diagram of the Buleryan thermal chamber
Right there, at the exit, a valve with a cut out quarter, which was discussed above, is installed. It is advisable to leave a gap of at least a millimeter around the entire circumference of the valve. It will not allow it to jam due to the build-up of soot and other deposits, or due to its thermal expansion. The door, or rather the blower itself, is, on the contrary, equipped with a valve, similar to the throttle in a carburetor. That's what they call it - throttle. It should be able to tightly block the air flow if necessary.
From the inside, the door is covered by an additional metal plate, which serves as a heat shield. And along its perimeter and, accordingly, the perimeter of the loading hole, a gas seal is installed. Which is like two skirted flanges put together, only large diameter. The gap can be sealed with non-flammable, soft material based on asbestos or modern fire-resistant material. The “potbelly stove” itself must have legs to be installed at a certain distance from the floor, usually twenty centimeters or more. Especially if the floor is made of flammable materials. Self-production Bullerjan, the matter is not entirely simple and will require special tools and capabilities. This task is not something that all craftsmen and craftsmen can handle.

Buleryan stove with water circuit
More than one person had the idea to create a Buleryan with a water circuit. Perhaps this idea has a right to life. Let not the entire combustion surface be heat exchange, as in conventional liquid boilers. This is compensated by a spacious firebox. And the heat exchange area turns out to be similar. Convector pipes are “implanted” into a liquid heating system and the boiler operates like a regular boiler. But additional improvements are needed here.
Since the heat capacity of water is much greater, it is necessary to ensure greater energy efficiency. This means higher temperatures. Therefore, it is necessary to protect the furnace surfaces from burning. Allow the stove to operate at elevated temperatures using high-calorie fuel. And here savings during smoldering and the need for high heat transfer for the water coolant come into conflict. The meaning of the pyrolysis chamber disappears when solid hydrocarbons are used. Therefore, such experiments can occur in the case of a certain calculation, or in the absence of strict requirements. You should not place the contour around the chimney. Cooling it with water will lead to accelerated contamination and increased moisture condensation on the internal walls. Such options exist, but the effectiveness of such a system is questionable. Rather, it turns out to be a homemade water boiler of a bizarre shape.
Buleryan furnace under development
Some “creators” want to make a buleryan during testing. How to do this and is it worth the candle? You immediately need to decide for what needs such a miracle will be used. This modification is acceptable in the case of household heating. premises, garages and others. Where the slight “aroma” of free mining is not scary and there is a well-functioning chimney. And in general there is good traction in the system. The waste is burned as fuel in two ways. One method is less complicated and costly. This is a trickling evaporator. Its device is very simple.
At the entrance to the firebox, a casing-pipe is mounted, which on the outside contains a bowl for burning oil. And on it, a small container with a reserve is mounted. The tap regulates the stream of waste, which, falling into the bowl, splashes, burns and evaporates. Interior It is a metal canopy-partition, similar to the upper partition of the furnace. Only gases bend around it at the far wall.
They also practice a more mechanized and technological method. It is also more complex. Requires the installation of an industrial or homemade nozzle at the inlet of the furnace for burning waste. In addition, the mining must be applied under some pressure. In addition, it must be cleaned so as not to clog the nozzle. On average, users report consumption at two liters per hour. With free supplies and accompanying conditions, this option has the right to life.
Buleryan with hob
Someone may be asking the question: “Is it worth buying or making a buleryan with a hob or even a burner?” The determining factor here is the user’s readiness and ability to bring all elements of the stove, and most importantly the chimney, to compliance with the design parameters. If the chimney is high enough and thermally insulated. There will be no long horizontal sections, the wood is dry, and the stove itself is made correctly. That presence hob with a burner will only be a plus. Smoke can come through the burner when lighting in a cold room in the cold with damp wood. If the chimney system does not meet the requirements.
Unfortunately, often, missing or not understanding one, but important point, people are quick to criticize the entire idea or product. Hob may be present, it is only necessary to make some changes to the design in advance. At a minimum, the length of the plate separating the main firebox from the secondary firebox should be shorter. This will open up more space for the heat coming from the primary chamber. Accordingly, the burner should be placed above this gap. In the factory version, all the subtleties are already taken into account.
In total, your task is to provide traction. And at the moment of opening the burner, cover the vent and, if necessary, open the damper on the pipe. For those who have lived in the village and used a stove, no questions will arise at all. The city dweller will need to adapt a little. Nothing can be done without this. Is it possible to live in smart home with remote control.
How to install Buleryan
If you have decided on the drawings of this stove, its configuration, or in general, welded it yourself. It's time to clarify how to install Buleryan. As has been said more than once, buleryan warms the air. This means that its installation location must allow it to heat the room or rooms as efficiently as possible.
Naturally, the center of the room will be best place. But I think that not everyone will make such sacrifices. The exit can be special air ducts, with the help of which warm air can be distributed throughout the premises. This is especially true when there is a large area or heating several rooms. When installing the oven on a floor made of flammable materials, it should be protected sheet metal on non-combustible insulation 15 mm thick. or arrange a fire-safe podium, 15-30 cm high. In any case, it must be protected from possible sparks and coals, within a radius of half a meter from the ash pit or ash pit. Distance from combustion door to the opposite wall, at least 1250 mm. To wooden, unplastered walls, at least 1 m, plastered 0.7 m.
Chimney device
When installing a chimney indoors, please note that:
- No more than two storeys.
- The distance to unplastered wooden walls is at least 0.7 m.
- Distance of thermally insulated pipe, up to wooden wall, not less than 0.25 m, subject to maximum heating of the outer layer, up to 90 degrees.
- The height of the pipe should reach a length of 5-7 meters (depending on the power).
- When conducting metal pipe through the ceiling, cutting with fireproof materials is required insulating materials, at a distance of 0.5 m.
- The chimney must consist of a minimum number of segments, hermetically connected. Horizontal sections undesirable.
The outer part of the chimney must be insulated.
It is necessary to organize the possibility of easy cleaning and draining of condensate.
And the top point of the pipe must protrude above the ridge or roof, based on the standards, by at least 0.5 m. Good thermal insulation of the pipe is extremely important for this type of stove. Increased formation of resinous substances, soot and condensation, as a result of poor insulation, can cause overgrowth of the chimney lumen and other “smoked” delights. The use of resinous wood, raw fuel, and the burning of industrial and household waste are especially fraught. As a result, the desire to clean, as they say “burn off” the soot, can result in a soot fire. And these are temperatures over a thousand degrees. Such experiments are very dangerous and often lead to fires.

How to properly drown buleryan
Well, now that almost everything is known, let’s briefly talk about how to properly drown buleryan. First, it is advisable to put dry fuel into the firebox in the amount necessary to warm up the chimney and form coals. Moreover, it is advisable not to clean out old coals and ash at all, leaving a layer that will slightly cover the metal, protecting it from burning out. Open the chimney damper completely, and the ash pan, based on the required ignition speed and other factors, dryness of the wood, windy weather.
When the first “dose” is about two-thirds burned, quite a bit of heat will be generated. You can make a basic stash of large ones, but I highly recommend dry firewood. It is important to understand that slow burning or smoldering occurs within 500 - 650 degrees. Which means damp firewood, resinous wood, waste containing chemicals and adhesives, all this will leave deposits and moisture on the walls of the chimney at an accelerated pace. Also, do not use coal or coke. The air that acts as a coolant will not have time to remove all the energy from the surfaces of the exchanger. And most of it will fly down the chimney. Moreover, the increased temperature of the gases in the chimney will increase the risk of soot burning, and the metal of the firebox will burn through.
Buleryan stove convection air flow diagram
So, the heated chimney will ensure ignition and further combustion in the desired mode. And this is most likely an economy mode. Maximum economical, buller works with the vent and damper closed. The combustion process will begin to include the afterburning effect of pyrolysis gases. If we reduce the access of air through the ash pan, the gases formed due to a lack of oxygen in the main firebox will additionally burn in the upper chamber, separated by a partition. At the inlet, hot air is sucked in through the injectors.
With its help, the gases will release more energy during slow smoldering of wood. From below, under the stove, colder air is picked up by the draft created by the already heated flow in the convector pipes and “shoots” upward. Convection processes force air masses to circulate in the room, which provides a high heating rate, which is why the buller is valuable. It is worth noting that, due to its special design, the temperature of the outer surfaces of the oven remains quite low. This reduces the fire hazard and burns are much less likely. To do this, you need to “look” for a hotter place.
Guide to using Buleryan:
There is a lot of confusion among buyers - what is the difference between the Buleryan stove and the Breneran stove? The answer is - nothing. These brands of stoves in Russia were made at the same factory by the same people. Buleryan is the old name of these stoves, the copyright holders of this brand are Canadians, at their request the production of stoves under this brand was stopped, and they began to be produced under the Breneran brand. So essentially it’s the same thing, but both names stuck.
Buleryan long-burning stoves are all-welded steel structures. Pipes into which air flows are welded around the cylindrical combustion chamber. The air flows are heated by the heat generated by the furnace, after which they are released upward. That is why, almost immediately after lighting such a unit, the air in the pipes heats up to 60-90 °C, and rising, heats the entire room.
Due to the ability to warm up as quickly as possible and the high efficiency of the unit, furnaces of similar designs are highly valued by owners of industrial workshops, greenhouses, workshops and even residential premises. Absolutely complete combustion of fuel is achieved thanks to an additional smoldering mode - gas generation.
When it is turned on, the firewood begins to smolder very slowly, which can be regulated using special valves that reduce the access of air into the firebox and partially block the exit of furnace gases. These gases enter the upper chamber, equipped with special injectors - afterburners, which inject fresh air flows that ignite the fuel gases. This allows about 90% of the fuel energy to be converted into heat, which is a very high figure.
These long-burning stoves also differ:
- durability;
- reliability;
- high performance.
With their help, you can heat rooms from 100 to 1000 cubic meters. Any type of organic material can be used as fuel - wood waste, peat, sawdust, bark, waste paper and much more. Wide door and the volumetric firebox make it possible to use even very large logs that do not need to be split.
The further from the city - those cleaner the air is clearer than the river, greener than the foliage. Vacation home or country house far from highways, factories and other signs of civilization - a treasured dream many of our citizens.
However, as life shows experience, distance from the city to the dacha in direct ratio number of elementary amenities on the last one.
Sewerage, electricity And heating make life and relaxation in the lap of nature much easier, especially if this vacation occurs during cold season. The heating issue in this case becomes the most burning. If water can be brought from a well or spring, then light a fire in the house if desired. will not work.
If dimensions housing allow, you can build and install a classic Russian stove, which will warm your home with warmth and comfort even in the most harsh winter. Another option is or. Everything would be fine, but these devices are known high fuel consumption, rapid cooling and require additional operating costs.
But there is also third option, which combines the advantages of , and “potbelly stoves” - this is convector ovens. One of the best representatives of this type of heating are Buleryan stoves.
From this articles you will learn not only the basic principle of operation And device these stoves, but also the reasons why these heating devices are so popular worldwide.
History of creation
According to one from versions, the appearance of Buleryan was facilitated by professional fellers from Canada. Character and conditions their work required the creation of a heating device with the following characteristics:
- Compactness designs;
- Fast room heating: country house, cottage; good example.
- Minimum number of bookmarks;
- Wood fuel.
However patent for the invention of a furnace that meets the desired characteristics received German engineers. German company Bullerjan GMBH, appeared in 80s of the XX century – first began serial production of Buleryan stoves. The devices immediately gained immense popularity thanks to reliability and the simplicity of its design.
In Russia Buleryan stoves are produced under the brand "Breneran". Already more 10 years lets them in Russian company "Laotherm" under license from a German manufacturer.
Construction of the Buleryan furnace
Design the heating device is quite simple. Externally- This is a steel cylinder with curved pipes coming out of it. Most of all, the device resembles oven-heater- a device whose operation is based on principle convection of air flows. And this is not surprising, because this is exactly what was taken as a basis.
Housing material – structural steel, coated with heat-resistant paint. Steel thickness varies from 4 to 10 mm. Curved towards the center pipes, “recessed” into the buller (body) by two thirds, thus constituting part main furnace mechanism.
Inside housing is located two-tier firebox. It is not protected, and its volume directly depends on the volume main cylinder. Perforated steel sheet divides combustion chamber on two tiers: upper and lower.
In the lower tier, the processes of smoldering wood fuel and generating generator gas occur.
Upper compartment takes approximately 7% total area of the chamber. Here is carried out afterburning volatile compounds coming from bottom fireboxes
Furnace door Buleryan, like the body, is made of become. Although in last years very popular models with inserts from heat resistant glass. The door is quite wide (this is necessary for storing large logs), hermetically sealed, equipped with a secure lock. Located on it air regulator with movable throttle- a smoke damper that regulates the draft force and allows choose oven operating mode.
Such modes at the device two:
- Kindling mode. Thanks to this mode, it happens quick heating ovens. Installed in the combustion chamber working temperature, and the heat generated is uniform distributed throughout the heated area;
- Slow burning or gasification mode. The combustion chamber is filled with a large volume of firewood, which smolders as a result of setting the smoke damper to minimum air supply. Prolonged combustion promotes constant heat generation at economical wood fuel consumption ( 1 bookmark for 10-12 hours).
Principle of operation
As mentioned earlier, for basis Buleryan's stove-heater was taken. The main feature and difference from other convector-type devices is this special a system of pipes passing through the combustion chamber.
Step by step the working principle looks like in the following way:
- Main building warming up in kindling mode and provokes suction of cold air through the buller pipes;
- Passing through the tubular system, the air heats up before high temperatures And thrown up through outlets;
- As a result, it happens fast warm-up the entire room. Cooling down, the air settles again at floor level and again enters Buleryan's heating system.
Movement air masses are carried out only due to natural convection. Air passing through pipes doesn't enter in contact with fire, maintaining comfortable humidity and oxygen saturation.
Advantages and disadvantages of the design
Main positives characteristics of Buleryan:
- Fast and even heating premises;
- Easy to install, operation And service;
- High Efficiency - 80% ;
- Economical consumption fuel materials;
- One of the most long periods of work among furnaces (on one fuel stack);
- Versatility of use(the device can serve dachas, country houses, garages, shops, greenhouses, greenhouses, farms, hangars and much more).
But this heating device also has flaws:
- Buleryan works only for one type of fuel – woody;
- To reduce the fire hazard of the device, it is imperative to insulate the chimney pipe;
- Dust burning on the furnace body causes an unpleasant odor;
- As a result of combustion, caustic gas is formed in the chimney condensate which requires removal.
Note: The level of condensation in the chimney of the Buleryan stove can be reduced if only dry wood is used as fuel.

Fuel selection
Two modes of operation of the furnace determine and choice fuel. Buleryan works only for wood fuel. Use of other types, e.g. coke can lead to breakdown heating device.
In mode kindling placed in the oven fast-burning material (cardboard, wood chips, straw). The rapid warm-up period is from 5 before 30 minutes.
Mode long burning requires more "solid" fuels: firewood, wood and peat briquettes, pellets. And what? larger fuel, the better. Buleryan will accept even massive chocks.
At correctly configured smoke valve they will slowly smolder without requiring additional bookmarks.
Stove Buleryan – perfect example autonomous, unpretentious and inexpensive heating device. The design of the device is quite simple, which allows you to make it artisanal way. There would be a desire, and a pair of “golden” hands.
Look video about the design and operating principle of the Buleryan stove:
From my own experience I know that even the simplest purchase heating stove can cause a serious blow to the budget common man. Having studied the many available stove designs, I decided to give preference to Buleryan. A homemade modification of a well-known foreign heating stove has taken root perfectly in my garage.
Do-it-yourself Buleryan stove - drawings and assembly diagram
First, I prepared everything I needed to assemble the buleryan with my own hands. First of all, I took out from the pantry a drill with a set of drills for all occasions, a grinder with discs from the kit, welding machine, clamps and other little things.
I had to tinker with the materials. In order for the Buleryan to be truly reliable and of high quality, I decided to make it from heat-resistant boiler steel. This material is capable of providing truly long-lasting and reliable operation heating unit. Find the material mentioned in your personal household or buy it in a specialized store.
I also used 4mm thick steel sheet. A sheet measuring 100x200 cm was enough for me. Additionally, I needed a little (40x70 cm) 6 mm steel sheet, about 4 meters of pipe with a diameter of 11 cm, about 10 m of profiled pipe measuring 57x4 mm. In addition, I bought handles, hinges and latches for arranging the doors, prepared pieces of 35-centimeter pipe and, in general, several metal blanks just in case.
Homemade buleryan: a detailed guide
First I bent the 57mm pipe. To do this, I used a special tool - a pipe bender. I cut the pipe to 120 cm, and then bent it with a 225 mm radius.
As a result, I ended up with 8 pipes. According to the design of the buleryan, I installed 4 pipes on each side, arranging them staggered. As a result, the depth of the heating unit was 45.6 cm.
Then I made a "T" bend. I will then install it behind the Buleryan. This design will simultaneously remove smoke and collect condensation. Test it at the end. If everything is done correctly, the smoke will go up, and the condensed moisture will flow down.
A crane was installed underneath. A very convenient thing. As condensation accumulates, simply turn the tap and all the moisture will go away. I tried to keep the tap constantly open, but it’s better not to do this - unnecessary draft appears.
A damper was installed in the outlet to regulate the draft, as well as the intensity of combustion in the buleryan.
I fixed a similar, but already blind, damper on the vent of the entrance door.
To attach the dampers, I attached a spring to their axis. It presses the valves in the pipe more tightly and better secures them in the desired position. In general, the dampers “move” 90 degrees.
I took a 350x4 pipe and cut two 4-centimeter pieces from it. I cut one piece and stretched it, turning it outward. I inserted a shredder measuring 4x4 cm into the gap. As a result, I got 2 rings with diameters of 35 and about 36 cm. That is, one ring should fit calmly but tightly into the second.
The second ring is on the front wall of the buleryan.
I welded the rings into the places allocated for them. What bigger size, took it for the door. I made a third ring from the tavern - the inner ring for the door. As a result, it stuck inside the ring on the stove door and its wall. I sealed the gap between the rings on the door with asbestos cord.
The door should close as tightly as possible - this is necessary for normal gas generation. Of course, convection pipes can also cope well with this, however, after testing the design a lot, I realized that it is the tight door in combination with the dosed and controlled air supply that makes gas generation more efficient. Therefore, it is better to spend a little more time and properly seal the door.
A heat shield was welded to the door using spacers. Then I welded a corner to the screen. Thanks to the corner, a more uniform air distribution will be ensured. Additionally, the corner will not allow firewood to pass into the lid during closing.
After that, I made slits in the first pair of pipes and inserted injection tubes there. I used tubes with a diameter of 1.4 cm. The length was 15 cm. In my opinion, this is the most best option. The installed tubes will be in constant communication with the firebox through convection pipes, thereby ensuring combustion.
Then I welded the frame from steel pipes. Don't forget: you inserted the injection tubes into the first pipes. The following pipes are on their own.
Then I made a partition from a thick (I think it was about 6 mm) sheet of metal. If possible, use the thickest metal possible. It will get very hot in the combustion compartment and, if it is not thick enough, will burn out extremely quickly. It is best to make a partition according to a pattern - it’s more convenient. Make the pattern itself from thick cardboard to size.

Then I welded the space between the convection pipes. I also used patterns. First I made them from thick cardboard, and then cut them out of heat-resistant metal.
Made a castle. The design is simple: the eccentric is grabbed by a hinge attached to the wall of the oven, and while turning it presses the door against the body.
Making such a castle yourself is not very easy, but it is possible. You have to use a router and lathe. The design itself, as I already said, is extremely simple. At the same time, the lock is very effective.
I made the loops from cutters. You can use any suitable similar blank.
Then I mounted the air injector to the top of the front face of the case. In fact, it allows you to further regulate the combustion in the firebox of a homemade buleryan. The injector will open and close by turning the hole in the tubes.
I welded the legs to the buleryan.
I installed the chimney and loaded a test batch of firewood.
Buleryan flooded. Everything went great.
At this point the stove is ready. I’ll say in advance: in practice everything is a little more difficult than in words. But you can get a stove with an efficiency of 75-80% at minimal financial costs. Such a buleryan will be able to heat almost any space - from a barn to a living room.
After using this stove for a while, I decided to improve it. If you want, you can do the same as me.
The design features of the stove in question are such that it can initially distribute oxygen efficiently and evenly within itself. The tubes at the bottom draw in cold oxygen, and the heated air is discharged from those installed at the top. If you wish, you can provide forced circulation oxygen.
I took tubes of a suitable diameter and welded adapters from them to the holes of the stove pipe located below. I plugged the adapter at one end.
The other side was connected to the fan.
I decided to use “snail” fan models. To ensure their operation, in my case, a 90-watt motor at 2800 rpm was enough.
The results are excellent - after modification, Buleryan began to work even more efficiently.
I’m also thinking about connecting a corrugated cable to the upper outputs and routing them different directions- you will get a full-fledged heating system.
You can customize the instructions in your own way. I will be happy to read your suggestions and maybe even put something into practice.
My instructions will help you assemble a reliable, efficient, durable and productive stove with your own hands.
