Abstract

The invention relates to gas burners and m. used for burning waste low-calorie combustible gases of chemical plants with natural gas. The invention reduces mechanical and chemical underburning. Gas collector (GK) for natural gas and GK for waste gas are made in the form of inner and outer tubes (t) 5,6 coaxially installed along the axis of the housing 1. T 5 is outside T-6. Radial nozzles 9 and 10 are equipped with stabilizing fins 11, and a pilot burner 16 is installed along T 5 axis. Through nozzle 14, the main stream of natural gas is supplied, which from T 5 is distributed through pipes 9 and through nozzles 7 enters the recess (A) 13, where it mixes with the primary air and ignites. From the burner 16. After the A 13 is heated, waste gas is supplied through the nozzle 15. The latter enters through the pipe 6 of the Civil Code, the pipe 10 and the gas-emitting pipes 8 in A 13. 2 Il. I (L 15 flCk / af

Description

The invention relates to gas burners and can be used in the chemical industry, for example, for burning waste low-calorie combustible gases of chemical plants with natural gas.

The aim of the invention is to reduce the mechanical and chemical rains.

Figure 1 shows the burner, a longitudinal section; in fig. 2 shows a section A-A in FIG.

The burner contains: body 1 with a snail swirler

at the entrance, mounting flange 3, about

a seagull 4, installed in the housing 1 with an annular gap and forming with the side wall a swirler 2, an end gap, gas collectors for natural and waste gas, made in the form of an inner 5 and an outer 6 pipe coaxially installed along the axis of the housing 1 and 6, respectively outside the outer 6, gas nozzles 7 and 8 for natural and waste gas, located in the annular gap between the housing 1 and the shell 4, radial tubes 9 and 10 for natural and waste gas, connecting the nozzles 7 and 8 with hectares ovymi manifolds 5 and 6. The groove 10 and the tube 9 are provided with stabilizing ribs 11. With the mounting

After the embrasure 13 is heated, the nozzle 15 is supplied with a waste-low-calorie combustible gas of chemical production (for example, formalin waste gas), which burns very unstablely or cannot burn at all independently, but it has a calorific value. The combustible gas flows through the manifold 6, the radial tubes 10 and the gas supply tubes 8 into the embrasure 13. The air flow through the snail swirler 2 increases.

Claims (1)

Invention Formula A burner device comprising a housing with a snail swirler at the inlet, a shell installed in the corbel flange 3 a burner device fastens-35 with an annular gap and forms ceramic with the side wall of the cochlea of the torx 13 inlet to the metal lining 13. Collectors 5 and 6, the joint gap, gas manifolds with gas, are supplied with inlet pipes 14 and 15. Along the axis of the inner pipe 5 are suction pipes located in the annular gap between the body A pilot burner 16 for catfish and a shell and connected to a torch stability holding unit. The burner device operates as follows. The snail swirler 2 enters the air, which is distributed evenly around the circumference and is divided into two streams: the primary, which passes between the housing 1 and the shell 4, and the secondary between the shell 4 and the collector 6 and enters the embrasure 13. pilot burner 16 is supplied with TI-ORD gas, which is supplied to the sub collector by means of radial tubes, characterized in that, in order to reduce mechanical and chemical underburning, the gas collectors are made in the form of coaxial tubes arranged along the axis of the body, and and derived outside the outer pipe, mounted on the radial tubes stabilizing rib 50 and the inner tube axis Collector additionally installed pilot bitchka. 3071572 It is burned with the help of a third person and is burned in the secondary air flow. A pipe 14 is used to feed the main stream of natural gas j which from the collector 5 is distributed through the radial tubes 9 and through the gas filling pipes 7 enters the embrasure 13, mixing with the primary air and igniting from the pilot burner 16. As you move deeper into the embrasure, the burning mixture of natural gas and primary air is mixed in. fO After the embrasure 13 is heated, the nozzle 15 is supplied with a waste-low-calorie combustible gas of chemical production (for example, formalin waste gas), which burns very unstablely or cannot burn at all independently, but it has a calorific value. The combustible gas flows through the manifold 6, the radial tubes 10 and the gas supply tubes 8 into the embrasure 13. The air flow through the snail swirler 2 increases. Invention Formula A burner device comprising a housing with a snail swirler at the inlet, a shell installed in the housing with an annular gap and forming a front end with the side wall of the cochlea gas calling pipes located in the annular gap between the building catfish and shell and connected to collectors by means of radial tubes, characterized in that, in order to reduce mechanical and chemical underburning, gas collectors are made in the form of coaxial tubes arranged along the axis of the housing, the inner tube being extended outside the outer tube, stabilizing fins are installed on the radial tubes, and along the axis inner tube Collector additionally installed pilot bitchka.
