Steam combustion-supporting type torch burner

Abstract

A torch burner of steam combustion-assisting type consists of cylinder body, central jet pipe of steam, steam ring pipe, nozzle and jet pipe of steam-air. It is featured as setting nozzle jacketed on steam ring pipe far from top of cylinder body, aligning nozzle to entrance of jet pipe of steam-air and setting steam jet component far from high temperature region at top of burner.

Description

technical field [0001] The invention relates to a burner for treating combustible waste gas, in particular to a torch burner for treating combustible waste gas by using water vapor to eliminate smoke and assist combustion. Background technique [0002] The common torch burners are steam combustion-supporting type, blast combustion-supporting type and non-combustion-supporting type, and most enterprises use steam-supporting combustion-supporting torch burner. The basic principle of using water vapor to support combustion is: first, use water vapor to inject a large amount of air to support combustion, and then the water vapor reacts with carbon in the flame to prevent the generation of black smoke, reduce the temperature of the torch burner, and prolong the combustion of the torch device service life. [0003] The Chinese utility model patent No. 98236888.7, titled "Steam Fire Suppression Torch Burner for Empty Ignition", discloses a steam combustion-supporting torch burner....

AI Technical Summary

Problems solved by technology

[0004] 1. Because there is flue gas produced by combustion waste gas at the top of the burner, the flue gas contains a large amount of carbon dioxide, the product of combustion. When water vapor is involved in the air, carbon dioxide is also involved in the combustion area. Therefore, the device induces The ability to inject air is limited, the smoke elimination effect is not ideal, and the maximum smoke elimination capacity is not enough. Usually this kind of flare burner can only eliminate black smoke within 30% of the maximum load of the flare gas;

[0005] 2. The noise caused by water vapor injection is the main noise source of the water vapor combustion-supporting torch burner. It is much louder than the noise generated by the torch gas venting and turbulent combustion. The noise at the ground of the torch burner is generally 90 decibels Above, since the water vapor ring pipe and nozzle of the burner are arranged in the high-temperature area on the top, effective noise reduction measures cannot be taken to eliminate the huge noise generated by water vapor injection;

[0006] 3. The water vapor ring pipe and nozzles are arranged in the high-temperature area on the top of the flare burner, and its service life is not long enough. In addition, due to the injection of water vapor at the top, the high-pressure water vapor needs to continue to expand after passing through the nozzle. The flame suppresses and keeps the torch burner in a high temperature area for a long time, which will shorten the service life of the torch burner
