Problems solved by technology

[0015] However, Patent Document 3 does not disclose at all the structure and position of sensors that can confirm whether the ignition is on or not.
[0016] On the other hand, none of the patent documents consider at all the technology that can operate stably without the flame disappearing under unstable combustion conditions (compressed air instead of pure oxygen, etc.)

Abstract

The invention relates to a burner for waste gas incineration, which is used in a chamber for burning waste gas, comprising: a burner body (120), arranged separately from the waste gas inflow part; a fuel gas supply pipe (130), communicated with the burner body And supply fuel gas and first oxidant to the inside of the burner main body; oxidant supply pipe (131), additionally supply the second oxidant; more than one nozzle mechanism, the nozzle mechanism is used to control the flow of the fuel gas and oxidant And it includes two or more types of nozzles, and the nozzle mechanism is located inside the burner body and arranged at the rear end of the fuel gas supply pipe.

Description

technical field [0001] The invention of the present application relates to a burner for waste gas incineration used in a chamber for incinerating waste gas, and specifically relates to a burner for waste gas incineration with improved fuel for reducing the generation of nitrogen oxides, combined with the improved fuel, and improved combustion protection internal combustion structure. Background technique [0002] Exhaust gas emitted in semiconductor or display manufacturing processes, etc., especially SiH 4 ,DCS,NH 3 , F 2 ,NF 3 The toxicity, explosiveness and corrosiveness of the pollutants are strong, which is not only harmful to the human body, but if it is not purified and directly discharged into the atmosphere, it will cause serious environmental pollution. [0003] For the above-mentioned exhaust gas, the content of harmful components is legally regulated not to exceed the permitted concentration, and it needs to be discharged into the atmosphere after a harmless t...
