Abstract

FURNACE-FIREPLACE, comprising a casing, a combustion chamber, a smoke pipe, casing blinds, a door, a furnace louvre, characterized in that the furnace is made in the form of a casing with double side and ceiling walls and is equipped with a valve located in the ceiling of the furnace, a valve control lever, a frying pipe located on the rear wall and connecting the inter-wall channels to the furnace, and a pipe connecting the cavity between the casing and the combustion chamber.

Description

The utility model relates to the field of domestic heating furnaces with solid fuel, in particular on wood.

The metal furnace, consisting of a cast-iron box, firebox, ash pan, is widely known. A steel pipe leaves the box, through which gases are led to the chimney. 1

Also known is a metal furnace consisting of a metal box, a firebox, a casing, closed by a casing having openings for entering cold air at the bottom, and at the top for releasing heated (prototype)

A disadvantage of the known structures is that the combustion temperature in the firebox is reduced due to the strong cooling of thin metal walls and satisfactory fuel combustion conditions cannot be ensured. The walls of the firebox are very hot and quickly burn out, during the combustion process, sublimation of dust to the heated walls is observed.

The inventive utility model is aimed at creating a compact long-burning furnace, increasing heat transfer and efficiency.

The specified result is achieved in that the fireplace stove containing a casing, a combustion chamber, a smoke pipe, casing blinds, a door, a furnace louvre is additionally equipped with a valve located in the ceiling of the furnace, a valve control lever, a frying pipe located on the rear wall and connecting the interwall channels with the furnace, and the furnace is made in the form of a body with double side and ceiling walls.

control and the chimney and the implementation of the furnace with double walls allows for the survival of flue gases, increase the heat transfer of the furnace, reduce the amount of harmful substances in the flue gas.

In FIG. 1 shows a device, FIG. 2 is a diagram of the movement of flue gases with the valve open, FIG. 3 is a diagram of the movement of flue gases with the valve closed.

The household fireplace stove contains a casing 1 of sheet material, which encloses the combustion chamber 2, the smoke pipe 3, the louvres of the casing 4, the door 5, the louvres of the furnace 6. The furnace 2 is made in the form of a body with double side and ceiling walls and is equipped with a valve 7, located in the ceiling part of the furnace 2, the control lever 8 of the valve, a frying pipe 9 located on the rear wall and connecting the inter-wall channels and a pipe 10 connecting the cavity between the casing 1 and the flow chamber 2.

The furnace operates as follows.

Firewood is laid with gaps so that the furnace 2 is loaded up to the direct draft valve 9, without interfering with its free opening.

After kindling, the door 5 is closed, while the handle-lever 8, pressing the door to the body is in a horizontal position and the direct draft valve 7 is fully open. Firebox blinds are also open. In this mode, the furnace works like a potbelly stove, i.e. .

flue gases directly, bypassing the inter-wall channels of the frying pipe 9, exit into the chimney through the chimney 3.

Depending on the quality of the firewood (raw or dry), the direct draft valve 7 is closed in a few minutes by pressing the handle-lever 8 1/2. or 3/4 of the angle of rotation in order to reduce direct traction and accelerate heating of the furnace.

 U

j .- -s, After starting the kindling and reducing the number of firewood by about 1/3, reload. To do this, the lever handle 8 is lifted up until the door 5 is released and, having stood for several seconds to establish a direct traction, open the door 5. After the newly loaded firewood burns up, the lever lever 8 is completely lowered down. In this case, the direct draft valve 7 completely covers the upper hole, and the blinds 3 of the doors are covered, leaving gaps of 1 ... 2 mm.

Further burning of firewood in the combustion chamber 2 occurs with a lack of oxygen, which ensures long-term combustion of fuel. The gases generated during fuel combustion are heated to 600 - 900 C in the frying pipe 9. Heated air enters the frying pipe 9 through the pipe 10 and the gases are burned in the frying pipe 8 and the inter-wall channels of the combustion chamber with the release of additional heat. The afterburning of gases in the chimney increases the efficiency of the furnace. Then the flue gases exit to the ceiling part and then through the flue pipe 3 into the pipe.
