Abstract

A device for heating air comprises a cylindrical body with a perforated cylinder coaxially mounted to it, in the cavity of which a cylindrical air chamber is installed at the air inlet, holes are made over its entire surface, with processing between its surface and the perforated cylinder of the annular cavity, from one of the ends of which an annular wall is installed, and inside there are two annular perforated partitions with the formation of a preliminary displacement chamber between them, between one of them and a torus Eve wall - a gas chamber communicated with a nozzle gas inlet, and between the second annular wall and the cylindrical surface forming an annular cavity - the working chamber.

Description

Device for heating air

The utility model is intended for heating air in air heating systems of industrial and domestic premises.

A device for heating air is known, which has a housing in the cavity of which a perforated air chamber is installed at the air inlet, the openings of which are in communication with the working chamber, with a gas supply pipe / cm. A.Z. Kurbanov “Energy-saving equipment for autonomous integrated heat supply systems of industrial enterprises, Tver,“ Gere, 200 / g p. 47-48.

The disadvantage of this device is the incomplete burning of fuel in a wide range of its supply due to the fact that there is no preparation of a homogeneous gas-air mixture, which leads to the appearance of harmful emissions above acceptable values.

The technical result of the claimed utility model is to reduce harmful emissions in a wide range of thermal loads due to the active movement of jets of gas and air and the preparation of the gas-air mixture.

The specified technical result is achieved in the claimed device for heating air, containing a cylindrical body with a perforated cylinder coaxially mounted thereto, in the cavity of which a cylindrical air chamber is installed at the air inlet, holes are made over its entire surface, with an annular formation between its surface and the perforated cylinder cavity, from one of the ends of which an annular wall is installed, and two perforated annular are installed inside it

partitions with the formation of a preliminary displacement chamber between them, between one of them and the end annular wall of the gas chamber in communication with the gas supply pipe and between the second annular partition and cylindrical surfaces forming an annular cavity - the working chamber.

The utility model is illustrated by drawings, where figure 1 shows a General view of a device for heating air; figure 2 shows a side view of the device. A device for heating air comprises a cylindrical body 1 with a perforated cylinder 2 installed in it coaxially with it. A cylindrical chamber 3 is installed in the cavity of the cylinder 2 at the air inlet 3. Holes are made over the entire surface of the air chamber 3. Holes are made over the entire surface of the cylinder 2. Between an annular cavity is formed by the surface of the air chamber 3 and the perforated cylinder 2. In the latter, two annular perforated partitions 6 and 7 are installed, with the formation of a preliminary displacement chamber 10 between them. Between the partition 6 and the end annular wall 11 installed from one of the ends of the annular cavity, a gas chamber 12 is formed, in communication with the pipe 13 for supplying gas. Between the partition 7 and the cylindrical surfaces forming the annular cavity, a working chamber 14 is formed. In the working chamber 14, firing devices 15 and a control electrode 16 are installed. The device operates as follows:

Air by a fan (not shown in the drawing) is pumped (sucked) into the air chamber 3 and into the gap between the housing 1 and the perforated cylinder, from where it is fed into the displacement chamber through the openings 4 of the air chamber and the openings 5 of the cylinder 2.

Through the pipe 13, gas is supplied to the gas chamber 12, where the gas, distributed throughout the volume of this chamber, is supplied through the system of holes 8 in the partition 6 to the preliminary displacement chamber 10, through

holes 5 of the perforated cylinders 2 and holes 4 of the air chamber 3, air is supplied to the displacement chamber 10 in the form of a system of jets perpendicular to the gas jets entering through the openings 8. In the chamber 10, gas and air are actively moved and a homogeneous air-gas mixture is obtained, which through the openings 9 partitions 7 enters the working chamber 14, where it is ignited by the ignitor 15.

A device for heating air comprises a cylindrical body with a perforated cylinder coaxially mounted to it, in the cavity of which a cylindrical air chamber is installed at the air inlet, holes are made over its entire surface, with processing between its surface and the perforated cylinder of the annular cavity, from one of the ends of which an annular wall is installed, and inside there are two annular perforated partitions with the formation of a preliminary displacement chamber between them, between one of them and the end howl wall - a gas chamber communicated with a nozzle gas inlet, and between the second annular wall and the cylindrical surface forming the annular cavity of the working chamber.
