Oven — is a universal means for heating, using solid fuel. Although they had previously been presented only in the form of immovable constructions, over time, there is a more convenient and mobile solution. Among them bullerjan oven, which is considered one of the most practical, economical and reliable options to heat. Thanks to its design, it has excellent characteristics, making it ideal for many tasks.
Features of furnace bularian ↑
The advantage of this furnace compared to other options is a system of forced convection. It is equipped with numerous pipes, the design of which allows you to create a constant flow of air inside them. This leads to the fact that the time required for heating, is significantly reduced compared to conventional furnaces.
Among the main advantages of this option noted:
- High speed heating;
- The use of any solid fuel;
- Efficiency and high efficiency;
- The possibility of using in any room.
It is also worth noting that many furnace design buleryan support the ability of combustion control. This is done through control of air thrust through the pipe. This makes it a convenient equipment for room heating in spring and autumn.
Due to these advantages of this oven is a great success. Even the most compact model can easily heat a few rooms, and for large areas optional to buy the biggest version.
To work, you can use any type of solid fuel. Can be used as ordinary wood and coal, peat briquettes, paper and more. Of course, that high-powered burning rate will be high, so it is recommended to adjust the traction to save fuel.
The principle of operation of the furnace buleryan ↑
The basis of this furnace is a gas generator. It is through him we achieve high work efficiency. When the fuel burns, it emits gas which has high temperature. The process of combustion takes place in the lower chamber and the gas rises in the injector. In the process they evaporate and leave through the chimney, substantially raising the temperature through the design of the air. The efficiency of such a furnace is 80%, which is extremely high for solid fuel options.
The idea of air circulation is simple. At the bottom of the furnace has openings, in which comes the cold air. It passes through the tubes is heated and rises, which creates thrust. The result passes through the oven a huge amount of air for the short term, warming up to high temperatures.
To increase the efficiency of system is used afterburner. In the upper part of the chamber the products of combustion are subjected to high temperatures that allows to burn their remains and get more heat from the same batch of fuel. This oven also allows you to speed up space heating.
The peculiarity of such furnaces is the presence of a practical flap. It is a special power controller, which allows you to adjust the temperature. This allows you to adjust the oven under a suitable level of heating.
Based on this controller there are two modes of operation:
- Quick heated;
- Gasification.
In the first case, the oven works in an intensive mode, all dampers are open. This allows you to quickly burn the fuel in a matter of minutes to heat a room of medium size. The second option, gasification, allows you to extend the effect. The flap is placed in such a position that creates a slow stream of air. For larger flame, there is simply no sufficient air, so the fuel burns out gradually, heating the room. In this mode the oven can operate for up to days, while maintaining the temperature.
An interesting feature of the furnace buleryan is the ability to create a permanent home heating. Top tube is discharged into an adjacent room with the help of sleeves, whereby warm air is distributed throughout the house. However, it should monitor the thrust and the distance to other facilities, because not every model is able to cope with this task.
Preparations for the production ↑
Oven buleryan you can make yourself. Although it is not a simple task, this option is far cheaper than buying in stores. The price of this product is extremely high, so it is better to negotiate with a friend the welder and do it myself.
Needed for the production of the following materials:
- Metal shears;
- Bulgarian;
- Welding machine;
- Tool for bending pipes.
The materials needed are pipe, sheet metal and area. The thickness of the sheet should exceed 0.75 mm. The housing will be formed from tubes and sheet depending on the previously chosen design.
Oven buleryan their hands ↑
The process of creating the furnace is divided into several stages. They needed to prepare materials, form the basis and bond of all the parts into a finished product. The process is quite difficult, so may need help.
It is possible to allocate following stages of manufacturing of furnace:
- Preparation of materials;
- The formation of the frame and the frame;
- Fastening of the side walls;
- Creating a zone for the post-combustion gases;
- Mount the rear and front wall with door;
- Welding of the chimney and the final inspection.
In the first stage, prepare the materials for the furnace. Cut the sheet at the wall of the pipe bend with the necessary bias. The number of tubes individually and depends on the future size of the furnace. Corners are cut for the further frames.
Next is the formation of a frame and frame. The corners are joined under the frame, and the tubes themselves form the future form of the product. It is recommended to lay them on top of each other, alternately changing the direction of the ends.
Next comes the mounting of the side walls. There are essentially two options: pipe connection by means of strips of metal or the closure sheet. The first option involves the welding of strips of metal between the openings of tubes to form a one-piece sealed housing. The second option forms the body of the sheets, covering the pipe inside. Both options are good, but the second can be difficult to clean the furnace from the ash.
Next comes the creation of a zone for post-combustion gases. It is made of two metal sheets fastened together at an angle. They adjoin the rear wall and separated the opening of the chimney so that the gas to it can pass only through the narrow space. In front of the sheets have a little walk to the wall, enough space for 1-2 pipe.
You can then weld the rear and front walls. Previously recommended to carefully check the entire body for example of holes and gaps, because to eliminate them would be difficult. If all goes well, we can continue the work.
On the rear there should be a hole under the chimney, placed on the section, separated by metal sheets. On the front is already pre-prepare the door. Make it not worth it, better to buy at the store. So it will be safer and more practical. To adjust the power on the oven door or near it is recommended to install an adjustable valve.
Then welded the chimney and frame. After this careful inspection is carried out before the first start, and prepare the room for it. Keep the oven at a distance of 1 meter from the interior, and wooden structures. If this is not possible, you should spend a number of works on heat insulation with non-combustible materials.
The first furnace you need to gradually increase the temperature. It is expected that the design will expand in the heating process. This is a standard situation, which will also check the structural strength. If all goes well, the furnace can continue to use.
But before further operation of the furnace it is recommended to watch this video. Here is told the rules of the firebox, which will allow to increase the efficiency of products and increase its service life:
