DIY Buleryan stove



“When it comes to heating a room or house in the midst of winter, who are we to argue with Canadian lumberjacks?”
These are the words posted on the website of one of the manufacturers of the Burelyan furnace. Developed by Eric Darnell in 1975 in Vermont, this stove quickly gained popularity among American and Canadian lumberjacks. Over time, Eric founded the company and entered the European market.
DIY Buleryan stove


The popularity of this stove in its original design. Pipes are welded along the furnace circuit of the furnace, in fact, the pipes are the furnace. One end of the pipe looks up, the other down. When fuel burns in the furnace, cold air is sucked in through the lower hole and, after heating, exits through the upper one. According to some manufacturers, the efficiency of such a furnace reaches 80%, and the air temperature in the upper part of the pipe, after 15 minutes of burning fuel in the furnace, reaches 100-120 ° C.

Typically, a furnace is made of a round pipe. Master, for his the garage, I decided to make a furnace from a profile pipe. Working with a profile pipe is simpler, it does not need to be bent, but only cut at a certain angle and welded.
The drawing with the dimensions of the furnace can be downloaded here.

Tools and materials:
-Angle grinder;
- Jigsaw;
-Welding machine;
-Roulette;
-Marker;
-Hammer;
-Clips;
-Metal brush;
-Gon;
-Magnets;
Profile pipe 60X60 mm;
-Sheet metal;
- Aerosol heat-resistant paint;
-White Spirit;
-Metal core;
-Washers;
-Springs;
- Damper 70 mm;




Step One: Cutting
First, the master, at an angle of 45 degrees, cuts the profile pipe into blanks.



Step Two: Welding
First, the master made a template, and then welded sections from the blanks. After welding, it cleans welds.




Now the sections need to be welded together. Sections alternate, if on one section of the pipe the open side is looking in one direction, then on the other section in the opposite. In total, 4 sections need to be welded on each side. Then a metal strip is welded between the sections.







Step Three: Back
Now you need to cut and weld the back wall. In the wall, the master cuts a hole and welds a chimney with a diameter of 70 mm.






Step Four: Upper Section
In order that the flame does not fall directly into the chimney, the master welds a chipper from metal. Cut and weld two metal sheets. Welds them under the chimney.




Step Five: Airflow
This is what the master copied from the original Bullerjan that he had.These are two round tubes with three holes on the side and at the end. These pipes provide fresh air through the first two square pipes.

The master explains their purpose as follows: as soon as the fire reaches a certain temperature, the main air intake is blocked, and the formation of wood gas begins. Then the main air intake will pass through these two tubes.

First you need to weld the washers at one end of the pipe. Then you need to drill holes. Three small holes on the side and one large in the furnace section (for each tube). Next is welding. The openings on the side of the pipe should be directed in the direction in which the smoke will go.


Step Six: Front
Similarly, the back plate welds the front plate. Then marks and cuts out the doorway. Around the opening welds a strip.




Makes door and hinges. Welds the hinges and sets the door.




Seventh step: air duct
From the pipe makes an air intake. Inside it installs a valve. Welds the air intake at the bottom of the door.





On the inside of the door, a gasket from the profile pipe is welded. Welds the handle and gate valve from the spring to the door.







Step Eight: Painting
The last step is to paint the heater. Of course, this is not necessary, but it gives the stove a pleasant look. The master decided to paint his Bullerjan in matt black. Since the furnace heats up very much, you need a paint that can withstand such temperatures. Before painting, it is also important to clean the oven with a degreaser to get rid of dirt and oil.



Step Nine: Security
When operating the furnace, the master took care of safety. First, he installed the furnace on a metal sheet, and covered the walls around it with refractory material. Secondly, he got a fire extinguisher and installed a fire detector and a carbon monoxide detector.




The furnace is ready and the master is pleased with its work.







The whole process of making the furnace can be seen in the video.

and the fullest loading with its rawest chocks does not give the combustion manufacturer promised 8 ... 9 hours. And at the end of combustion, the stove bluntly cools the room (the pipe is open!)

I do not agree !!! Had experience with Buleryan. Actually, stuffing the firebox from evening, until the morning there was always enough. The stove does not cool the room, it’s not true !!! Because, firstly, in the evening both flaps were switched to pyrolysis mode, respectively, slightly open, only a small gap, and secondly, even if you do not toss in the morning, the coals remain hot for a long time - air is supplied in this mode very few, and mainly only in the upper (pyrolysis) combustion chamber. They open only to warm up to the "pyrolysis temperature" that you spend during the day ...
at the end of combustion, the draft is not enough to remove the products of combustion and begins to stink specifically with tar and burning.

Traction should be enough even without burning !!! You have a chimney of what height / diameter ??? Insulated? Maybe the reason is in it?
Because, at that time, I also saw the Buleran man who smoked and did not enter the pyrolysis mode. It just burned like a simple potbelly stove. And the reason was that he had a chimney - a simple pipe four meters high in total.

Of course, the author did a great job at a high level.I have been using an analogue (Brenneran) in the garage for about 7 years now. "The Beast Machine", but it also has many serious shortcomings. It didn’t occur to him to heat it with purchased pellets, and the fullest load of it with the rawest chocks does not give the combustion manufacturer promised 8 ... 9 hours. Moreover, at the end of combustion, the stove bluntly cools the room (the pipe is open!) It would be nice to come up with a metered supply of fuel (briquettes, chicks, sawdust) to the combustion chamber. The intake of heated air comes from the floor itself - dampness is removed. It would seem that the room should be well, very fresh air, nifiga! When laying the fuel, at the end of combustion, the draft is not enough to remove the combustion products and it starts to stink specifically with tar and burning. I would like to do, taking into account the shortcomings, something more perfect. And structurally simpler, as in the Author (Pogranets). The pipes in my store stove are round, the walls are much thinner but made (as written in the passport) of heat-resistant steel. I don’t think that the inventor is so stupid that he doesn’t know that it is easier to cook a square pipe than a round one, and a stainless steel is more expensive than 3kp ... So what's the trick?
Guest Alexander
Too complicated. Everything is made much simpler, the main thing is to understand the principle of operation of a long burning furnace.
Guest Yuri
Without going into corners, physics, and gas emissions, this is not a bad thing.
I just didn’t understand, - the author installed the stove on the attic (!!!). With such an installation, buleryan is no different from a potbelly stove - heats the ceiling of one room. So much fuss to get a cheap "potbelly stove" ???
By type of activity, I have seen many private construction projects, including in winter.
There were installation options, as a potbelly stove, as a rule, a temporary option for workers. Feet freeze ...
But there were also fixed installations (in homes for the poor at all).
In the second case, the furnace is installed as low as possible, right up to the basement (basement). The furnaces came across with the number of pipes up to 12-14. A metal corrugation is pulled at the ends of the pipes, which is bred onto the floor and even two above. Sobsno, pipes in this furnace, and are needed to connect the air ducts-heaters.
Guest Yuri
I had a Swedish version (cast-iron, with a glazed door). Without pipes, but the combustion system was regulated in the same way - by restricting the air supply.
When filling the furnace, it contained 10 kg of wood-sawdust briquettes. Mostly enough for a day, at an external temperature of -10 C.
The stove is good, but there are some unobvious points. Usually this is written below in small letters. Bake not intended for use in rooms where people have been staying for a long time - The air passes inside the pipes, which are very hot (above 60 degrees. Exactly). Dust burns on these surfaces and releases carcinogens. This is an oven for greenhouses, garages, workshops. Here's a water boulevard, that's another matter.
It can be seen that you are not in the topic ... Buleryan is exactly good because it is a long-burning pyrolysis furnace ... We used to fill it with wood in the nursery once in the evening, put up the shutters and enough until the morning ... For six- seven hours does not burn so as to go out ....
True, I had a large ... But its power was much greater ... Although a larger volume of firewood was laid, but they burned all at once ...
So, in this regard, he is good ... Only now ...
... Well, what should happen, what kind of apocalypse should occur in order to have to live in a house with a "stove"? )))) ... Tea, not besieged Leningrad ...))))

It’s good in the garage, for the home, you won’t have to go round the clock.
Guest Jura
If only someone would unsubscribe as a temperature in the house .... just not one of those who are looking for errors in the text.
If two profiles are folded over sections of 45 degrees, a right angle is obtained. The author has three pipes - and 90 degrees isn’t ... Or did I study poorly?
Guest Pavel
First, the master, at an angle of 45 degrees, cuts the profile pipe into blanks.

the “master” will have more degrees, at 45 we get a rectangular oven.the ratio of the size of the furnace door and
the chimney is wrong. In general, Buleryan must have a chimney with a diameter of at least 120 mm, otherwise instead of pyrolysis we get carbon monoxide generation (without color and odor, negligible doses lead to death).
the author of this miracle stove has a 70mm chimney. with such a volume of the furnace, if it is loaded at least halfway, there is a serious and serious risk that the chimney will not cope with the removal of gases and, if there is pyrolysis, we get a stream of fire from the duct, if CO is generated (the same carbon monoxide), we get a stream of carbon monoxide from all the slots and openings of the device, because the pressure in the stove will be much higher than the pressure in the room.
