The utility model relates to heat engineering, in particular to heating and heating appliances.

Known air heater containing a combustion chamber in which a burner is placed, a heat exchanger attached to the upper cover of the combustion chamber Ј USSR author’s swatching, S 11333, cl. F24 C 1 / 02.1958;.

A known design of a boiler made of sheet steel, including a housing, a furnace with a grate and a water-heat exchanger. Yu.P. Sosnin, E.N.Kukharkin Heating and hot water supply of an individual house: Reference manual.-M.: Stroyizdat, 1991.-p.33 /.

A disadvantage of the known devices is low maintainability.

The closest device of the same purpose to the claimed utility model according to the totality of signs is a heating furnace containing a heat exchanger, a housing inside which there is a combustion chamber with a grate and an ash pan located under it v Author svipetevEMIOSSSR, No. 370413, cl. F 24C 13/00, 1973; taken as a prototype.

A disadvantage of the known device is the inability to use several types of fuel.

The task is the heating of individual rooms, individual houses with a coolant-hot water.

The technical result is the expansion of the operational capabilities of the heating furnace.

the casing is made of brick, and the bricks are reinforced with a frame, drilled, strung on rods, the lower ends of which are attached to the bottom of the frame, equipped with a burner device located on the side wall of the combustion chamber, the heat exchanger is mounted on the casing, secured by the clamping frame of the frame to the casing, and the radiation part facing the combustion chamber, while the shape of the heat exchanger is made B in the form of a prism, for example octagonal.

Comparative analysis with the prototype allows us to conclude that the claimed heating furnace is distinguished by the presence of a brick casing, a burner, located on the side wall of the combustion chamber, a collapsible design.

A general view of the heating stove is presented on the Chetag. The heating furnace is made collapsible. The heating furnace contains a housing I. Inside the housing I there is a combustion chamber 2. Housing 1 is made of bricks 3, which are reinforced with a frame 4, which serves as the base of the furnace. The bricks 3 are pre-drilled, laid on top of each other on a refractory mortar and strung on vertical rods 5, the lower ends of which are attached to the bottom of the frame 4. The combustion chamber 2 has an opening with a door b for loading solid fuel, contains a grate 7 and an ash pan 3 mounted under it with a blow door 9. On the side On the wall of the combustion chamber 2 there is a burner device 10 for liquid fuel. A heat exchanger II is installed on the housing I. The heat exchanger II is fixed to the housing I by the clamping frame 12 of the frame 4 by means of tie bolts 13. The heat exchanger II is made in the form of an octagonal prism, includes a radiation 14 and convective 15 parts that make up the overall heating surface of the furnace. The radiation part 14 is made in the form of an octagonal prism and serves as a continuation of the combustion chamber 2 in its upper part. The convective part 15 consists of a tube bundle of steel pipes, the lower ends

- 2 of which are fixed in the pipe flange 16, restricting the combustion chamber 2, and the upper ends are fixed in the tube plate 17. The heat exchanger II is equipped with inlet 18 and outlet 19 water pipes. The furnace has a fume hood 20 with an outlet 21 for flue gases. Depending on the selected fuel, the heating furnace operates as follows. Solid fuel is thrown into the combustion chamber 2 on the grate 7, burned on it in the layer. Liquid fuel from the supply tank i is not shown in the drawing) is supplied to the burner device 10, with the help of which it is flared in the combustion chamber 2. Heat from the burning fuel is absorbed by the radiation part 14 and further by the convective part 15 from the exhaust products of combustion. the hole 21 in the hood of the smoke collector 20 goes into the atmosphere through the chimney C in the drawing is indicated on the drawing.) (the hood of the smoke collector 20 also serves as a safety device in case of an accidental explosion of gases, acting as an explosive rising under the action of excessive gas pressure above the chimney collector, the hood reduces the pressure in the gas path of the furnace and in the combustion chamber 2, preventing their destruction.The heated water enters through the pipe 18 in the lower part of the heat exchanger II and rising upwards, passes through the water circuit, washing sequentially the radiation surface 14, and then the convective 15 parts and heated to a temperature of 95 ° comes out through the pipe 19 in the upper part of the heat exchanger II. The burner device 10 operates in automatic mode at a given temperature of the coolant in the heating system and the air temperature in the room. Due to the design of the radiation part 14, which is a continuation of the brick furnace chamber, the heat exchange conditions in

the combustion chamber, the combustion conditions of the fuel and the furnace volume of the heating furnace is effectively used.

The use of a burner device on the side wall of the combustion chamber provides the ability to work on any fuel and quickly transfer from one type of fuel to another.

The use of a heat exchanger made in the form of an octagonal prism made of sheet steel allows for the use of a minimum of operations — a hoop and chopping — in its manufacture.

The use of brick masonry of the combustion chamber provides heat-storage ability and creates conditions for the use of low-grade, humidified moisture and low-calorie solid fuel.

The use of heating gechs in the form of a collapsible design allows you to quickly assemble on the spot, increases maintainability and durability.

The heating stove is designed for heating individual rooms and individual houses, while using several types of fuel: solid coal, firewood, peat briquettes; liquid - kerosene, diesel fuel.

The advantage of the utility model is the ability to use any type of fuel without prior conversion of the combustion chamber. At the request of the customer, it is possible, without changing the design of the heating furnace as a whole, to change the shape of the combustion chamber or the geometric dimensions of the masonry housing, to adapt it to work on any particular fuel.

At the same time, the operational capabilities of the heating furnace are expanded, the labor costs for its manufacture are reduced, the manufacturability of production is simplified and the scope of the heating furnace is expanded,
