But really, everything ingenious is simple: a rim with spokes and an axle in the middle - that’s the wheel, stretched fabric - a rain canopy, and metal cylinder and several pieces of corners and pipes to complete the look of the bubafonya stove from a gas cylinder.
The design drawing will be presented in the article below.
Transition to new technologies, use modern species energy, scientific and technological progress, all this, as practice shows, is gradually becoming part of daily life, but as the same practice shows, it is not always rational to install electric convector or carry out gas heating.
It’s easier, more reliable and cheaper to use an old, proven resource - firewood, coal or even industrial waste, such as sawdust or shavings, in order to ensure uniform maintenance of heat in the room for at least 6-12 hours.
Make a stove long burning, with fairly good heat transfer rates and at the same time not as voracious as traditional potbelly stoves and bulky like Burelyans, omnivorous and cheap in terms of manufacturing costs, you can do it yourself, using the bubafoni project from a gas cylinder as a basis.
The areas of application of such a heating stove are simply enormous, from garages and workshops to cabins and shift shelters, especially since the size of a 50-liter household gas cylinder can guarantee fuel combustion for at least 8 hours at full load and the air supply damper is open as much as possible.
Bubafonya, as one of the options for long-burning stoves, allows you to make one fuel fill for 16-24 hours, it does not require much attention, since combustion takes place in a hermetically sealed space, and does not have a traditional ash pan, so the risk of a fire from a spark running out in this case is minimal .
On the other hand, a bottle from a gas cylinder is extremely inconvenient for removing combustion residues; this will have to be done through the top cover. Another not entirely pleasant point for this type of stove is the relatively low heat transfer compared to other stoves, so it will not be possible to heat the room quickly.
The basis of the bubafoni design is gas cylinder, inside which the combustion process of wood fuel takes place. A special feature of this process is the principle of prirolysis - the decomposition of wood under the influence of temperature into flammable gases, which subsequently burn to form heat.
Wood combustion occurs in several stages, at the first stage, the fire heats the fuel, burning out flammable substances, and after overcoming the limit of 300 degrees, the wood begins to decompose into simple substances and combustion of pyrolysis gases occurs. The second stage of combustion is the most efficient, since the combustion temperature of the gases is about 700 degrees.
The possibility of obtaining gas combustion products and their efficient combustion in a furnace is achieved by dividing the internal chamber into two parts. The lower part, filled with firewood, produces the initial ignition and heating, but the upper part, separated from the lower part by a press with a guide air duct, is gradually filled with wood decomposition products, which begin to burn. A massive press gradually pushes the fuel down, thus facilitating the efficient process of firewood decomposition.
The smoke is finally discharged outside through a chimney, the opening of which is located in the upper part of the furnace, and the air supply to the combustion chamber is carried out through an air duct, which forms with the press single design. The air supply to the firebox is regulated by setting the damper gap in the upper part of the air duct.
The history of the creation of this invention can be interpreted in different ways, on the one hand, it is a successful reworking of the idea of an industrial design of a pyrolysis boiler, on the other hand, it is a wonderful use of scrap materials to create a new type wood stoves.
And although many argue that this is still the idea of the industrial Lithuanian boiler Stropuva, the fact remains that Bubafon still comes from Srednekolymsk.
Like all ingenious things, the bubafonya stove made from a gas cylinder is a fairly simple design, the manufacture of which will require the ability to work welding machine and some free time.
The main design is a gas cylinder with a capacity of 50 liters, this is the smallest cylinder in volume from which a normal stove can come out; cylinders of a smaller volume simply should not be taken into account, since the efficiency of their use is extremely low.
Note: You can use a gas cylinder as a stove body only after the remaining gas has been removed from it, otherwise, when you try to cut the cylinder, the remaining gas may ignite and an explosion may occur.
Preparation of the cylinder and all parts consists of selecting required size metal blanks and cleaning them from rust, oil stains and paint residues.
For ease of use, the cylinder is cut along the circumference at the top. The cut should be as smooth as possible and not have any distortions. It is best to make the cut along the weld line of the top of the cylinder. In the cut off cover, the valve is removed and the guide hole is reinforced with a larger diameter pipe.
Legs are welded to the cylinder in such a way that the lower part of the cylinder is raised above the floor level by 20-25 cm. The legs are made from a thick corner of 30*30 or 40*40 mm.
A hole is made on the side at a distance of 50 mm from the upper edge of the body and a pipe 400-450 mm long with a diameter of 120-150 mm is welded at an angle of 90 degrees. It is advisable to make the chimney from a thick-walled pipe.
Considering that the diameter of the cylinder is 300 mm, a disk with a diameter of 270-280 mm with a hole in the middle of 80-100 mm is cut out of metal 8-10 mm thick. A pipe with a diameter of 80-100 mm and a length of 1200-1400 mm is welded to this hole exactly at an angle of 90 degrees. This is an air supply pipe; a plate valve is welded at the top of the pipe to adjust the air supply hole.
From the bottom of the press, in order to distribute air evenly throughout the volume of the combustion chamber, metal strips, corners or a “U”-shaped profile are welded so that the rays go from the center to the edges. To ensure that the air spreads evenly and only the central part of the fuel load does not burn out, a plate 8-10 mm thick with a diameter of 200-250 mm is welded to the center over the corners.
The furnace is installed on a rigid, solid base; if the furnace is planned to be used as stationary equipment, it is recommended to weld the handles only to the furnace lid. If you plan to move the stove from time to time, it is advisable to install handles on the body.
Despite the fact that the stove does not make any special demands on the quality of the fuel, it is still necessary to dry it before adding firewood; dry firewood, even of a smaller volume, produces heat longer than wet wood.
It is important to know that while the boiler is operating, the fuel supply can be periodically replenished. But it is impossible to stop its operation or turn it off until all the firewood is completely burned.
Despite all positive traits, the oven has a significant drawback: it heats up too slowly required temperature in room. Achieve a large flame in as soon as possible very difficult.
Based on this, the most correct way to increase efficiency is to use additional technical solutions, contributing to an increase in the process of heating the air volume in the room.
The only effective method to increase the heating rate is the need to install an additional casing made of corrugated or flat metal on the body 2-3 cm from it to create an effect when cold air, heating up between the body and the casing, rises, creating a significant air shelf.
Today, among all the popular models of wood-burning stoves, the Bubofonya stove is the only one effective remedy real cost savings and effective use resources. Moreover, such a stove can be assembled using minimal investment.
How to make a long-burning stove, see the instructions in the following video:
It's not just living spaces that require heating. Often in chicken coops, barns, and greenhouses it is also necessary to maintain a stable temperature. If you like to tinker in the garage or have a workshop where you do what you love, then most likely you know that in winter time It can be very cold there during the year. It is irrational to build a full-fledged stove or buy an electric heater. There is a cheaper solution - a bubafonya stove. It can be drowned solid fuel at the time when it is necessary and turn it off when it is not needed. Its popularity is very high. It belongs to long-burning stoves and uses fuel economically, while releasing maximum heat. You can do it yourself.
The efficiency of a conventional wood-burning stove is 50%. The remaining half of the heat escapes into the air. This happens for one simple reason, the name of which is pyrolysis (thermal decomposition, which produces flammable gases). They require more time and higher temperatures to ignite and release heat than a standard oven. Therefore, together with carbon dioxide These gases escape irretrievably into the atmosphere. , offered on the market, have an efficiency of about 90%. The fuel burns in them at very high temperatures. high temperatures and quite slowly.
Standard pyrolysis boiler - complex design for self-production, requiring special equipment and skills. The Bubafonya stove is an ingenious prototype of this complex machine. You can build it yourself without difficulty. It is ten times more economical, and its efficiency is no worse. The ideal fuel for it would be a mixture of wood and coal.
This is the simple way bubafonya works
The bubafonya stove is quite simple. To make it, you can use an old forty-liter gas cylinder or a two-hundred-liter barrel. The cylinder has less heat dissipation and operates for about 8 hours. This option is suitable for small spaces.
You can also make a potbelly stove from a gas cylinder to heat your garage. Detailed assembly instructions are presented in our material:.
Think carefully about the place where you will install the stove. Although it cools quickly, it reaches very high temperatures during operation.
Bubafonya from a gas cylinder
The barrel is better in this regard. It can heat a room for up to two days and will do an excellent job of heating hangars, large workshops, and so on.
Its unpresentable appearance needs to be slightly modified in order to be placed in a residential area. To do this, it can be covered with natural stone or bricks. In addition, they will become a kind of heat accumulators.
Bubafonya from a 200 liter barrel
In addition, you will need a couple of pieces of steel pipe, a grinder, welding, a chisel, hacksaws for metal, electrodes and a chisel.
Before manufacturing itself, you need to decide on the size of the oven.
Length of the cylinder and chimney Dimensions of the cylinder and outlet pipe Diameter of the chimney Dimensions of the pancake with blades
If the stove is supposed to be heated not only with dry wood, then the pipe should be extended downwards and a place should be made to collect condensate.
Drawing of the furnace indicating all details and dimensions
Such a stove has many advantages: its low cost, ease of creation, high efficiency. But there is also a disadvantage of this design: it supplies heat unevenly. The solution may be to blow it with a fan. But it's inconvenient. To solve this problem, a water “shirt” was invented. To create it, you will need another cylinder, the diameter of which will be larger than the furnace body itself.
The project clearly shows the placement of the water “jacket” on the chimney and the connection of water heating and radiator to it
In fact, the water “jacket” is a kind of improvement of the furnace, to which heating equipment can be connected. The “shirt” can be installed in two places: directly on the body and on the chimney pipe. Both places heat up well. In order to put on this very “shirt”, you need to use a pipe with a larger diameter than the place where you are going to put it on. The open ends of the pipe must be thoroughly welded and the inlet and outlet pipes where the heating devices will be connected must be welded into it. The operating principle is simple. Water passes through the jacket, heats up and carries heat into the room.
You should not forget about the operating rules and safety when using any heating equipment, including furnaces in production. Detailed instructions on installation in our article: .
It is not difficult to assemble such a stove yourself. Of course, visually it is not very attractive. But if you install it in non-residential premises But, say, in a garage, this will not matter. The main thing is that it is powerful enough to heat the room. And if you wanted to use such a structure for heating a house, then it can be beautifully covered with brick. In general, good luck to you!
With the approach of cold weather, every responsible owner begins to think about organizing heating own home. If heating system has already been equipped for a long time, it will only need to be checked before being put into operation.
In the absence of a heating unit, you will have to make much more important and responsible decisions, the first of which will be the choice of a boiler or furnace - the “heart” of any heating system.
To date, many different heating units have been developed and successfully tested in practice. Compared to its closest analogues, an interesting unit with no less interesting name- Bubafonya stove. Of course, you can do the assembly of such a stove yourself.
A simple-looking stove combines many important advantages, among which the following points must be noted:
To assemble a bubafoni, you do not need any expensive or hard-to-find materials. A tank, a lid, a few pipes and various simple metal products will be enough.
The oven copes with its main task perfectly even in very very coldy. Bubafonya can be used to heat a residential building, greenhouse, garage, country house and other objects.
The unit is characterized by a high indicator fire safety– in its design there are no holes for the exit of an open flame.
The main difference between the bubafoni design and its closest analogues is the modified firebox - the loading is placed in the upper part of the fuel compartment, and not in the lower part, as in most other units. As a result, the heated air falls down, simultaneously drying the fuel located below, and the load itself burns out as efficiently and effectively as possible.
The firebox is designed so that the wood burns in uniform layers, and not simultaneously throughout the entire volume, which contributes to a significant increase in the efficiency of the stove.
A damper is installed at the top of the furnace, allowing the user to independently select the desired burning intensity of the load. To stop burning, it is enough to simply completely block the access of air to the stove using a damper, and the fire will quickly go out.
Also among important features bubafoni needs to be allocated a very long combustion duration on one load of fuel. The finished stove has a fairly compact size and quite attractive appearance.
To install the stove, you need to allocate a separate boiler room with high-quality ventilation.
To connect the bubafoni to the individual heating system, you need to build a so-called unit around the unit. water jacket and connect it to the heating pipes. Heating of the coolant (water) will be carried out through the red-hot metal wall of the heating unit.
It was previously mentioned that fuel combustion in a bubafon starts from the top. But there is also a modification with bottom combustion. If you wish, you can assemble such a stove. In a bubafon with bottom combustion, a special door is installed to regulate the combustion duration.
However, modification with top burning fuel is much more efficient, productive and cost-effective.
IN self-production Bubafoni has absolutely nothing difficult. Prepare all the required equipment for work and get started.
First step. Cut carefully top part barrels. If there is no barrel of suitable volume, the furnace body can be made from a welded sheet or an empty gas cylinder.
Second step. Cut a 100mm hole in the center of the cut top circle.
Third step. Weld a pipe of the same diameter to the hole prepared in the previous step.
Fourth step. Weld four pieces of metal channel crosswise to each side of the circle. The resulting pressure circle will press down the loaded fuel and also facilitate the flow of the required volume of oxygen into the combustion chamber.
Fifth step. Prepare a fuel loading door at the bottom of the housing. To do this, cut through with a grinder rectangular hole, weld the canopies to the resulting piece of metal and place the door in its proper place.
Sixth step. Using a similar scheme, arrange a hole below the firebox to clean the stove from ash.
Seventh step. Cut a hole with a diameter of 100-150 mm in the upper side of the case. You will connect a pipe to it to remove gases and provide the required level of draft in the unit.
Eighth step. Make a knee out of chimney. To do this, cut a piece of pipe at approximately 45 degrees, turn the resulting pieces over along the cut and weld at the joint to form a strictly right angle.
Ninth step. Weld one side of the created elbow to the body. On the other side of the elbow, weld a long (4-5 m) pipe for drainage flue gases from the premises.
At this point the stove is ready. All that remains is to install it correctly.
Tenth step. Prepare the foundation for installing bubafoni. To do this, dig a hole with dimensions of about 100x100x20 cm, fill the bottom of the pit with a layer of crushed stone and fill it with liquid solution. Let the poured mortar dry, and then lay a couple of rows of brickwork over it.
After the masonry has completely dried, install the stove.
Eleventh step. Place a reflector near the bubafoni. During operation, the stove gets quite hot, and the reflector will provide additional fire safety.
The reflector will also contribute to a more uniform and high-quality distribution of heat throughout the heated room.
To make such a reflector, use heat-resistant materials available to you. For example, quite often such screens are built from brick.
If you wish, you can resort to other methods of making bubafoni. There are 3 of them in total.
All further actions are performed in exactly the same way as in the large instructions discussed earlier.
For burning bubafoni, you can use wood and various products of its processing (briquettes, sawdust, pellets, etc.). The main thing is that the material is dried as efficiently as possible - the efficiency of the heating unit directly depends on this.
The fuel must be placed in the tank, compacted thoroughly and set on fire. To speed up ignition, you can place some paper or rags soaked in kerosene on top.
After loading the fuel and igniting it, it is enough to return the piston and lid back, let the wood burn, and then adjust the intensity of the stove at your discretion using the dampers.
To make it convenient to use the bubafone, and to make the stove itself as efficient and safe as possible, remember the following simple recommendations:
Now you know how to make a bubafon and you can quickly solve all the problems of organizing the heating of your own home and any other room with your own hands. There is nothing difficult about this - just follow the instructions given and everything will work out.
Good luck!
It is impossible to achieve a comfortable microclimate in a house in winter if it does not have a competent heating system. Good heaters- this is not a cheap pleasure. It is also worth noting that due to constantly rising electricity tariffs, heating devices operating from the network are simply becoming economically unprofitable. Good decision One of the heating problems in private homes is the Bubafonya stove, which is quite easy to make with your own hands. Its peculiarity is that when minimum costs fuel, Bubafonya from a gas cylinder can heat very large area. This is very attractive to those who know how and love to save.
Those who are at least a little familiar with physics know: when heated warm air rises, but the cold one remains below. The operating principle of the device is based on this physical law. The fuel warms the air, which rises and enters a special exhaust pipe. Cold air through a special inlet pipe, gets inside and again heats up, enters the outlet pipe. Thus, not only fuel combustion occurs, but also air circulation. The intensity of combustion, and therefore the air temperature, can be adjusted using a special damper, which is located on the supply pipe.
The operation of the Bubafonya stove stops only after the firewood has completely burned out and the piston with a load is lowered to the bottom of the fuel tank. If the fire needs to be extinguished forcibly, it is enough to block the supply of oxygen. To do this, close the valve on the outlet pipe. You can also use water to quickly extinguish the flame.
The operation of the Bubafonya stove has the following advantages:
Disadvantages of the Bubafonya stove:
Before you start making the Bubafonya stove with your own hands, you must equip a suitable workplace. Most the best option- is to carry out all outdoor activities in warm time of the year. The only thing you need to remember is that access to the power supply must be free and convenient. If it is not possible to sit outside, then utility room or the garage can become good place for work. It is also necessary to prepare necessary tools and materials. Be sure to prepare drawings of the bubafonya stove with dimensions.
In order to make the Bubafonya stove without much effort, you will need the following materials and tools:
After the workplace and materials have been prepared, the time comes when you can begin directly assembling the Bubafonya stove. Regardless of whether it will change heating device its location or not, mandatory arrangement of the foundation is required.
Attention ! The foundation not only helps to position the heating device in the desired position, but is also an important fire safety measure.
In order for the base under the Bubafonya stove to be strong and durable, only refractory bricks should be used in its construction. The shape in this case does not matter much, the main thing is that the material is intact.
To better understand how to properly equip the foundation, consider clear example construction of the base for the Bubafonya stove with a volume of about 200 liters.
Before you start laying out the foundation walls, you need to make a small depression, about 20 cm. The perimeter of the hole is 4 meters (one meter on each side). The result should be a square with equal sides. Then crushed stone is evenly poured onto the bottom, after which the liquid solution is poured. Cement mixture should reach the edge of the recess. After the solution has completely dried, the foundation base is completely ready.
To build the foundation walls, fire-resistant bricks are used, which are laid out along the perimeter of the prepared foundation. It is very important to check the quality of work with a level. As a rule, no more than two or three rows of bricks are laid out. They also need time to set, after which we can say that the construction of the foundation is finished.
The stove can be constructed from any container; very often Bubafonya is made from a gas cylinder. Prepare a gas cylinder, cylindrical barrel or pipe required diameter. If a piece of pipe is used in the work, then one of its edges must be welded on one side with a lid made of a metal sheet.
If the work uses a barrel or a gas cylinder, then in this case, on the contrary, the bottom is carefully cut out. After which a circle with a diameter slightly less than the diameter of a barrel or gas cylinder is cut out of a metal sheet. In the middle of the circle, using a grinder, we cut out a hole of such a size that the supply pipe can be welded to it. It will be designed to allow oxygen to enter the fuel tank.
The edges of the embedded circle are welded metal channels. This must be done in such a way that you end up with a cross. This design will allow the fuel to be evenly distributed throughout the firebox, as well as provide access to the required volume of oxygen.
The final stage in the construction of the main part of the Bubafonya stove is the manufacture of the lid. To do this, a hole is made in the cut out bottom, the diameter of which coincides with the supply pipe.
It is also important to prepare a special place in the Bubafonya stove where firewood or other fuel material will go. To do this, place the heater in the operating position and at a distance slightly below the middle on the side wall, make a mark along which the hole will be cut.
Advice ! Most suitable sizes for it to be about thirty centimeters in width and height. As practice shows, these are the parameters that allow you to add firewood of almost any size to the firebox.
Just below the place for firewood, a special place should be made through which the Bubafonya stove can be cleaned of combustion products: ash and ash. This arrangement principle is very similar to a potbelly stove. If there is an opportunity and desire, then both holes on the side wall can be closed with doors. This will give aesthetic appearance Bubafonya stove and will prevent burning coals or wood chips from falling out. It is very important to install special latches on the doors that will keep them firmly closed.
To avoid deformation of the housing due to excess smoke, you need to install a chimney, having previously prepared a place for this. Approximately 20 cm from the highest point of the Bubafonya stove, make a marking to cut a hole for the chimney pipe along it. The diameter of the hole and the cut should be the same.
It is very important that the chimney has an elbow. In order to mount it you will need two cuts. One longer one is placed vertically. A smaller piece is welded to it at an angle.
Important ! The smallest section of the pipe should be no more than 45 cm long, otherwise the smoke will pass through with problems.
The pipes are welded at an angle of 45°. It is imperative to ensure that the edges of both cuts are in close contact with each other. Only after all parameters have been checked can the pipes be welded. A longer, vertically located pipe should go outside through the roof of the house. If the length is not enough, you can always add it by welding another cut. The hole in the ceiling through which the chimney exits to the roof must be coated with fireproof clay.
If the chimney must go outside through a window, then the pipe is not located vertically, but in a horizontal position. In this case, you need to remember that the smoke will come out much more slowly.
Advice ! The Bubafonya long-burning stove tends to become very hot, especially if the combustion process occurs continuously. Therefore, it is very advisable to install reflectors around the Bubafonya stove. For this purpose, foil is used, which is laid out under the bottom of the oven and around the entire perimeter.
You can use wood to light the Bubafonya stove different varieties or wood processing industry products (sawdust, pellets, etc.) The main thing is to monitor the quality of the material. The wood must be well dried, because the performance of the unit directly depends on this. Firewood must be placed in the tank, compacted well and ignited. To ensure that the ignition procedure takes place as quickly as possible, you can add a little rag or paper to the tank.
After the wood begins to burn, you should close the lid of the Bubafonya stove tightly and allow the flame to flare up at full strength. Only after this the intensity of the flame can be adjusted using the damper.
The video shows the results of experiments using different types fuel for furnace
To make using the Bubafonya stove comfortable and efficient, just remember a few simple tips:
You can upgrade the device as follows:
The heating stove, combined with a water heating system, is ready for operation.
The Bubafonya long-burning stove can operate with equal efficiency on any flammable substance. But there are still some differences: the duration of autonomous operation and the efficiency of the boiler depend on the type of raw material.
The following materials are suitable as fuel:
As a conclusion to the article, I would like to summarize:
