SU1462063A1 - Method and apparatus for burning up gaseous fuel - Google Patents

Abstract

The invention can be used in the combustion of natural gas in the furnaces of thermal furnaces and improves the efficiency of gas combustion and ensures the stability of the flare. The gas mixing pipes 5 are inserted into the gas burner plate 3 and are directed by their inlet sections towards the air flow. The pipes 5 have nozzle holes 8 on the side surfaces, and the individual pipes at the entrance have washers 9. A part of the fuel is mixed with the fuel and divided into separate jets. The stabilizing jets formed by pipes 5 with washers 9 are evenly distributed between the streams of the main plume formed by the pipes 5. The outflow of stabilizing downturns is less than the flow rate of the streams of the main torch, which ensures the reliability and economy of gas combustion. 2 Il. (and with

Description

The air-gas mixture exit speed from the exit sections 6 of the pipes 5 forming the jet stabilizes is smaller, the flow rate and the speed of the exit of the pipes 5 forming the jets of the main torch is reduced, which reduces the danger of the flame detachment, ensures the reliability of the flame stabilization

on separate streams, and stabilization. The lysis streams are evenly distributed between the streams of the main plume.

The ratio of the outflow rates of the stabilizing jets and the bruis of the main plume can be maintained at 0.13-0.95. For carrying out the method, a device for burning gaseous fuel can be used, comprising a cylindrical air intake housing 1 with an air-gas manifold 2 and a gas burner plate 3 with openings A. The housing 1 is provided with axially mounted

tazommesitelnymi pipes 5, wound-35 fuel mixed with air, separate their output sections 6 into the holes 4 of the gas burner plate 3 and directed their input sections 7 towards the air flow. The pipes 5 are passed through the air-gas manifold 2 and are provided with nozzles 1 and holes in the collector zone 2

8, made on the side surfaces of the pipes 5. The inlet sections 7 of the central gas mixing pipe 5 and part of the pipes 5 located in the peripheral zone are equipped with washers

9. The gas-air manifold 2 has an inlet section 10 for supplying primary air and forms a ring 11 in housing 1. A second channel 11 for supplying secondary air communicates with the space between the pipes 5 and the openings 4. The collector 2 is provided with a gas supply 40
