Description

one

The invention relates to gas-burning devices and JMO / KCT to be used in heating and thermal furnaces.

A device for burning fuel is known, comprising a casing and an annular channel plugged from the ends, a air inlet in the side wall, as well as counter-arranged radial fuel pipes and branch pipes for exhaust gases, which are connected to the annular channel and an annular channel connected to the source and; ku air pipe P.

However, in this design, the combustion chamber is rigidly connected to the housing, and the connections for the discharge of combustion products are made uncooled, which leads to the occurrence of destructive deformations during operation.

The purpose of the invention is to increase the reliability of the operation of the device. This is achieved by the fact that the gas outlet nozzles are installed with the formation of an annular gap in the air supply holes, and their inlet ends are introduced into the cavity of the chamber.

In addition, the inlet of the annular channel is made in the form of a box located along the length of the body coaxially with the fuel nozzles, and has a confusion-diffioreal profile) J sechepp, coinciding with

diametrically cross-section of the combustion chamber, R nozzles for exhaust gases are installed in the air supply holes with eccentricity, the value of which increases from the middle of the chamber to its ends.

FIG. 1 - burner, longitudinal section; in fig. 2 - the same, transverse section.

The burner includes a housing 1, a combustion chamber 2, installed: 1 in the housing 1 with the formation of an annular channel 3. On one side wall of the chamber 1 there are 4 openings for air supply, and on the other - counter spaced radial fuel eople 5, and 6 inlets The exhaust gases are fixed with the formation of an annular gap in the air inlet 4, the inlet 7 of the annular channel 3 is made in the form of a box and has a co-fusorioid, diffusor profile in section 1, which has a diameter of combustion chamber 2.

The burner works as follows.

Air enters through the pipe 7 into the annular channel 3 and then through the feed ports 4; Air into the combustion chamber 2. Gas from the manifold 8 through the radial fuel fuel Eople 5 also enters the combustion chamber 2. The mixture of gas with air, which is ignited and the combustion is gas-air) exists within the confines of chamber 2. B.

Claims (3)

Claim 1. A device for burning fuel, comprising a housing and a combustion chamber muffled at the ends with an annular channel installed in it and provided with openings for supplying air in the side steak, as well as opposed radial fuel nozzles and gas outlets, the annular channel being connected to air source 5 pipe, characterized in that, in order to improve reliability, the pipes for exhaust gases are installed with the formation of an annular gap in the holes for air supply, and their input zayu vedeny ends in the chamber cavity. 2. The device according to π. 1, the fact that the inlet pipe of the annular channel is made in the form of a box located along the length of the housing coaxially with the fuel 15 nozzles, and has a confuser-diffuser profile in cross section coinciding with the diametrical section of the combustion chamber. 3. The device according to π. 1, due to the fact that the nozzles for exhaust gases are 20 are installed in the air supply openings with an eccentricity, the value of which increases from the middle of the chamber to its ends.
