Novel low-pressure air combustion supporting torch combustor

Abstract

The invention relates to a novel low-pressure air combustion supporting torch combustor which is jacket structure form that a torch gas distributor is arranged in a barrel. Through design of the direction, the number, the distribution and the hole diameter of spraying holes in the torch gas distributor, torch gas is sprayed towards low-pressure air with a certain angle in space, and in other words, direct current cross mixing is conducted; and through the mixing manner, the torch gas and the low-pressure air can be sufficiently mixed, and the effect of smokeless combustion is achieved. To prevent flame blowoff, a fin plate structure is arranged at the proper position of the torch gas distributor, and fin plates are provided with a plurality of proper holes. Through design of the torch combustor structure, the torch gas and the low-pressure air are subjected to rotational flow mixing, and the purpose of removing black smoke is achieved. By utilization of reasonable control over the combustion area position, the purpose of reducing the combustor surface temperature is achieved, and combustor burning losses are prevented.

Description

technical field [0001] The invention belongs to a novel low-pressure air combustion-supporting torch burner, and in particular relates to the structure of the low-pressure air combustion-supporting torch burner. Background technique [0002] Industrial torches are widely used in petrochemical, coal chemical, refining, coking, fine chemical and other energy and chemical enterprises. They are used to release various flammable and explosive gases in the chemical industry when processing equipment is on / off, under normal working conditions and emergencies. Provide the last barrier of safety. At present, the emission of heavy hydrocarbons in the chemical industry requires that the total amount of combustion products and residues, as well as the emission rate and ground concentration are within the allowable range of the regulations; flammable and harmful substances should be burned and decomposed into harmless and non-combustible substances as fully as possible. Produces black s...

AI Technical Summary

Problems solved by technology

The structure proposed by the patent CN 206755166 U is an internal mixing structure, which has great safety risks such as explosion, and is easy to freeze to block the outlet of the torch in cold regions, and the technology of the steam-assisted combustion type torch burner in the prior art is very mature. For example, patents such as CN201120287259 and CN201520563616 all adopt the principle of steam combustion-assisted smoke suppression, and the smoke suppression effect is very obvious

However, due to the limited environment of the torch site, the steam-assisted combustion torch is not suitable for use in environments such as water shortages or cold weather.
