Make oven bubafonya their own hands - a step by step procedure

to heat a small room such as a garage, a country house or a beehive with the onset of cold weather, you can buy an expensive heater powered by electricity or to make their own long burning oven.Oven "Bubafonya" is designed so that one tab of the solid fuel is enough for a long time.But given the low cost of the fuel itself, the design, its simplicity and autonomy "Bubafonya" received wide distribution in the budget of owners of residential and non-residential premises, seeking to protect their holdings from freezing.

The principle of operation of the furnace "Bubafonya»

According to the law of convection, warm air rises and cold falls downwards.The fuel combustion furnace at a heating air rises and enters the discharge pipe.The cold air through the supply line falls inside the furnace.Thus, by constantly coming oxygen, supported by fuel combustion.By adjusting the value of the gap (using the throttle) on the feed pipe, you can increase or decrease the intensity of the burning wood.

furnace stops operating after the complete burning of firewood and lowering the piston with the load on the bottom of the fuel tank.Forced to complete this process as possible, blocking the access of oxygen to the furnace valve on the supply pipe.Or, using fire-fighting equipment, to immediately complete the heating system.

The principle of operation of the furnace long burning

By advantages furnace "Bubafonya" include: the duration of combustion, ease of construction, low cost of fuel and furnace elements, ease of operation, the possibility of an oven self-assembly at the proper level with the welding machine handling skills,small size and weight (oven that can move if necessary).

Despite the apparent profitability of construction, it has a number drawbacks: inconvenience of cleaning the bottom of the fuel tank by combustion products (soot, ash), the formation of condensation on the pipes (which reduces the efficiency of the furnace), in a classic performance furnace is not well accumulate heat (thatrequires either design a water "jacket" or the lining of the furnace insulation materials and masonry), heat it at the bottom of the fuel tank be installed in a layer of non-combustible material or to build a small foundation for the operation requires good ventilation in the room.

Main furnace elements "Bubafonya»

• - Fuel tank (it was charged directly to the fuel, and here is its combustion);
• - directs heat pipe (using a clamp and heat-insulating material is connected to the main pipe of the heating system);
• - Pressure circle with the load and the supply line;
• - flap;
• - cover furnace.

Tools and materials required for the construction of the furnace "Bubafonya»

• - Pipe metal 2 pcs .;
• - metal container under the fuel tank (metal barrel or other similar metal cylinder with a sealed bottom) with a wall thickness of not less than 3 mm;
• - Bulgarka (grinder with a cutting and stripping circle);
• - Hacksaw for metal;
• - Stretches sill or metal parts;
• - Welding machine with electrodes;
• - hammer, a chisel;
• - steel sheets.

metal barrel is perfect for housing for the furnace

Fuel Tank Capacity

where fuel will be placed, we will be doing a metal barrel.

1. Make the layout and cut the upper part of the barrel. For this we use a hacksaw or grinders.

Cutting Bulgarian require cutting disc for metal.Bulgarian size does not matter.At work it is important not to put excessive force on the tool.

In the case at hand only hacksaw on metal, you have every minute or two to take breaks in order to prevent overheating and subsequent breaking of the cutting blade.This method is very time-consuming, but the benefits financially.

Metal jigsaw

When finished barrels not, then constructing a container made of sheet steel.But it will need additional tools: Hand sheet bender, sheet bending machine or ingot, which can be used to give the sheet a cylindrical shape.

tank furnace of steel sheet

to bend the sheet manually (roller) listogibov one of its edge fixed clamping beam, then fold the sheet in the desired range.

Once the sheet is rolled into a cylinder, welding machine and brew joint.To establish this grounding sheet metal and welded edges go out preventing electric arc.By the way on our website has great benefits as cooking electric welding.If to withstand the same distance between the workpiece and the electrode, the seam has a straight and smooth.

When the cylinder is ready, a piece of sheet steel by marking Bulgarian cut and welded to the bottom of it.

When the fuel tank is ready, at the top of doing layout work discharge line .The layout can be done easily with a spray paint or pencil.By marking grinder to cut a hole to which the welded pipe.This pipe will be connected to the pipeline for central heating systems.

Pressure circle and cover

again take the steel sheet and do the layout of the circle.Its diameter should be slightly smaller than the diameter of the fuel tank.This is necessary to ensure that the pressure range of freely around inside the furnace.In the center of the circle cut a hole equal in diameter to the diameter of the inlet pipe.But no less than ten centimeters.This will provide the necessary access of oxygen, and traction.Likewise we are building cover for the tank.For convenience, it is desirable to be welded to the outer part of the lid handle of a metal rod.

Sample long burning furnace

length feed pipe taken on the basis of the length of the fuel tank and added to the value of 30-50 cm. The diameter should be about fifteen centimeters.The tube is connected to a clamping range of welding.

To add a clamping range of mass and increase its strength, welded 4 sill length or metal parts.

is welded to the pressure range of 4 sill

oven door for cleaning of ash and ash

Classic version of a furnace "Bubafonya" inconvenient to clean from the combustion products.They are sintered, and at the bottom of the plaque is formed.Clean the bottom of the ash through the door, the fuel tank at the bottom of the cut, it is much more convenient.

Make marks on the tank body, cut out a rectangular region of the metal grinder.By this rectangle metal loops welded to the future door could be opened and closed.To sheathe the perimeter of the door sealing asbestos cord.

Reflector

This part of the structure is designed to protect the furnace components from overheating and for proper heat distribution.

Foundation

Metal furnace elements have become hot property.For fire safety structure ready for use "Bubafoni" mounted on a foundation of concrete or refractory brick.

For devices from a brick foundation prepared a rectangular pit shallow, the bottom is paved with a mixture of sand and fine gravel, tamped and check horizontality building level.Thereafter, a cement slurry is prepared and spread two rows of refractory bricks.Brick in the front row are placed "on edge."

If instead of brick planned pouring concrete, then on the pillow of sand and gravel set wooden formwork, which is poured concrete.A space between the shell and pit densely covered with sand.
