At the beginning of the 20th century, people invented potbelly stoves. They were indispensable helpers in winter in various conditions. However, they spent a lot of firewood, which quickly burned out. Therefore, in the future, another design was invented, it is now popularly referred to as "Bubafonya" - a long-burning stove. It can give off heat much longer than ordinary potbelly stoves, because the fuel in it burns out gradually.
What is the difference between the burning process of an ordinary potbelly stove and "Bubafoni"
In potbelly stoves, fuel (firewood) burns very hot and fast. For this reason, its efficiency is low. The fire had to be contained. It was decided to compress all the laid firewood so that they do not burn, but smolder. In fact, this is the same potbelly stove, but only with a fuel press. And the name "Bubafonya" came from the name of the person who posted information and drawings of the furnace design to the World Wide Web. Since then, this model has become very popular and widely used.
What you need to make Bubafoni
Here is a drawing of the Bubafonya furnace, which makes it easy to understand the elements of its design. It is made simply, the main thing is to have a welding machine and find the necessary materials. The ideal material is an old gas cylinder. However, it can also be made from a barrel or pipes whose diameter is large enough for the Bubafoni case. We will also need tools:
- welding machine and everything for welding;
- grinder or cutting torch;
- gas cylinder or metal barrel;
- metal pipes with a diameter of 10 cm.
Material for making
The ideal Bubafonya stove made from a gas cylinder, this is the most suitable material, and besides, it is easy to find. All actions with it must be performed in the order that will be described now. The safety of the master who will do all the work depends on this.
First of all, you need to twist the valve. This will allow any remaining gas that may have remained inside to escape. Then, through the hole, you need to pour water into the internal cavity of the cylinder. This will allow you to be sure that in the process of cutting it, nothing will ignite or explode.
Next, you need to cut off the top of the balloon, its hemisphere. This will be the lid of the oven, so it will be in the same place in the finished model, but we'll put it aside for now.
Further, making the Bubafonya oven with their own hands, they build a press that will put pressure onfuel, preventing it from overheating. It is made from sheet steel, cutting out a circle that should easily pass inside the cylinder. A hole with a radius of 10 cm is made in its center. After that, a pipe with a diameter of 10 cm is welded to it, and a length slightly higher than the cylinder. This internal structure is heavy enough to compress the fuel, and the chimney will ensure that the minimum amount of air is passed through to sustain the combustion. Thus, the wood inside is rather slowly smoldering than burning. Because of this principle of operation, "Bubafonya" - a long-burning stove - got its name. After all, it is really capable of providing heat from 6 to 20 hours from one tab.
After that, a hole is cut in the middle of the cut-off hemisphere of the cylinder, a pipe should fit tightly into it, which ensures the flow of air to the fuel. After that, we can assume that the Bubafonya itself is done. Now you need to weld the chimney. To do this, a hole with a radius of 10 to 15 cm is cut out in the wall of the cylinder, under the lid itself. After that, they take a pipe of the same diameter and create a knee - this will be a chimney. It is welded to the hole. In principle, that's it, the simplest Bubafonya stove, the reviews of which are so positive, is done, you can try to flood it.
Stoking Bubafonya
To kindle the stove, you need to lay firewood inside the cylinder and let it flare up a little. When they are engaged, the inside of the stove is installed on top of them, which will press. Then onthe outgoing pipe is put on a cover from the upper hemisphere of the cylinder. Handles can be welded on it for ease of use. The smoke that is released from burning fills the cavity of the cylinder above the metal pancake, which is a press, and the top cover, after which it goes into the chimney.
Important little things
To prevent combustion products from escaping into the room, the lid and the top of the cylinder must be well sanded for better contact. You should also make a hole in the lid with high quality, into which the pipe for supplying air to the furnace passes. If the master takes into account all these design nuances, then the “Bubafonya” (long-burning stove) will heat the room well, and there will be no garbage and smoke smell from it.
In such an oven, you can load any kind of waste lumber from wood. Sometimes you have to make the press heavier by welding pieces of metal onto it. How much to increase the weight, during operation it will become clear.
Pyrolysis oven upgrade options
When the "Bubafonya" burns, or, more precisely, smolders, the case gets very hot. This is inconvenient in the sense that standing near her is too hot. The way out is to create a shirt around the body, which can be made from ordinary tin. They take a piece of galvanized steel, which is as tall as Bubafonya itself,. And they make a pipe out of it so that it is 5–10 cm wider than the stove itself. It turns out that the “Bubafonya” (long-burning stove) is red-hot, and gives off its heat to the internal space between it and the shirt, from which the latter also heats up, butsignificantly less. This allows you to feel comfortable near the hearth, without fear of getting burned. The place where Bubafonya will be located also needs to be protected from its high temperature. It is necessary to put refractory bricks under it or cast such a pedestal for the furnace from heat-resistant materials.
All these improvements will ensure not only the convenience of using the unit, but also prevent the risks associated with fire safety.
The Bubafonya stove with a water jacket, which will heat the whole house
The stove can heat water with the heat of its body, which can be put into the heating system of a private house. To do this, make a water jacket around the body. It is a metal box, or barrel, in which the entire body of the furnace is placed and filled with water. When the "Bubafonya" is hot, its temperature heats the water, and it can already be transmitted through the heating system. Thus, the Bubafonya stove, created with your own hands, can act as a boiler that heats the house. When creating a shirt, it is very important to weld it well to avoid leakage. The wall thickness should not be less than 3 mm. Also, if the "Bubafonya" fits completely into the shirt, you will need to make another cover that would cover the entire structure.
Another option for creating a water jacket is shown in the photo. It can be seen from it that a compact heat exchanger is located around the Bubafoni case. It heats water and delivers it through pipes to batteries. As you can see, the design takes up very little space.
In thisarticle, we have fully studied the topic of how to make a stove. "Bubafonya" at home is built from materials that most people throw away or scrap. We also learned various modifications of the device.
Rules for the safe use of Bubaphoney
- Flammable objects should not be placed near the oven: paper, plastic, furniture.
- Better to wear construction gloves to load fuel.
- Do not use flammable liquids to light the oven. But in the case when the fuel does not ignite, it is worth moistening individual pieces of wood with combustible material. After that, put it in the furnace with the others and only then carefully set it on fire.
- If you need to cook food on the Boubafon, do it only when it is fully warmed up.
- Do not touch any part of the oven to avoid burns. If, for any reason, this must be done, then it is worth wearing thick heat-protective gloves. After all, as described above, the body of the bubafoni is very hot.
- To turn off the stove, you need to close the damper on the pipe through which air is supplied to the furnace. After that, it will turn itself off after a certain time.
- To make the stove work for a very long time, do not burn plastics or polyethylene in it. Firstly, these materials emit toxic gases, and secondly, they leave carbon deposits in the system, which are very difficult to remove.
- It must be remembered that resinous woods often form condensation on the working surfaces of the stove, this can interfere with combustion.
- Don't paint parts"Bubafoni", because when it is heated, the paint can release toxins.
- The oven must be installed on a non-combustible substrate.
Afterword
There are many improvements, but the scheme of operation is the same, as shown by the drawing of the Bubafonya furnace, located at the beginning of this article. Therefore, regardless of which option the reader chooses for himself, you should always adhere to the rules set forth here. This will allow you to safely heat the room, and the unit itself will serve its owner for a long time and regularly.
