Abstract

The invention improves the economy and can be used in gas burning devices. An air manifold 8 is located under the fuel collector 1. The collector 1 is equipped with nozzles 4 and plates 2, 3 inclined relative to the other, and the collector 8 is equipped with nozzles 9 and plates 10, 11 inclined one relative to the other. The plates 2, 3 are provided with openings 7 and form 10 8 with plates 10, 11, air distribution channels 129 13 with a variable flow cross section, decreasing with distance from the air collector 8. The edges of the plates 2, 10 and 3, 11 are fastened together to form slit holes 14, 15. The burner can be set on in the air stream. During the operation of the burner, gas is supplied through the collector 1 through the nozzles 4, and the air through the collector 8 through the nozzles 9. From the collector 8, air enters through the openings 7 of plates 2 and 3, and also comes out of the slit openings 14, 15. The velocity of the air leaving through the slotted holes 14, 15, exceeds the speed of the incoming air flow, and it collides with gas jets flowing out of the nozzles 4, which provides an increase in the intensity of turbulence, leading to a reduction in fuel consumption to maintain combustion and increase the efficiency of the burner. 2 Il. i About sd Js5 00 ky

Description

Fm.g

The invention relates to a power system, can be used in gas combustion devices, and is an improvement to the technical solution of auth. No. 877233.

The chain of the invention is improved economy

FIG. 1 shows a burner, a general view; fig 2 - the same cross section

The gas burner contains a cylindrical straight-line fuel manifold 1 with a stabilizer in the form of longitudinal inclined relative to each other plates 2 and 3 and nozzles 4 placed between the latter in two inclined relative to each other longitudinal radial planes 5

and 6.

The angle between the planes 5 and 6 of the axes, the nozzles 4 is 60 ... 90e, and the plates 2 and 3 are installed parallel to the planes 5 and 6 and are provided with transverse rows of holes 7 arranged with a pitch equal to the pitch between the nozzles 4, and with an offset from the last half of this step.

The burner further comprises an air manifold 8 with nozzles 9 and. inclined plates 10 and 11. The collector 8 is located under the collector 1 and the plates 10 and 11 form with the plates 2 and 3 air distribution channels 12 and 13 with a variable flow cross section, decreasing with distance from the air collector 8. In this case, the angle between the plates 10 and 11 may be 50 ... 70 °.

The edges of the plates 2, 10 and 3, 11 are fastened together with the formation of a gap

outlets 14 and 15. A burner can be installed in the air stream.

The burner works as follows.

Gas is supplied through the fuel manifold 1 and through the nozzles 4, and air through the collector 8 and through the nozzles 9. Air from the collector 8 enters the combustion zone through the openings 7 of plates 2 and 34 and also leaves the slot openings 14 and 15. Moreover, the air velocity coming out of the slit holes 14 and 15 exceeds the speed of the incoming air flow, and it collides with gas jets flowing out of the nozzles 4, which provides an increase in the intensity of turbulence of the gas-air mixture flow and an improvement in mass transfer processes leading to a reduction in flow fuel, to maintain combustion and to improve the efficiency of the burner.
