Description

Technical Field

[0001] The utility model relates to the technical field of burner cleaning devices, in particular to a cleaning device for a coke oven gas low-nitrogen burner. Background Art

[0002] The coke oven gas low-nitrogen burner is a device specially used for the combustion of coke oven gas. Its main function is to reduce the emission of nitrogen oxides generated during the combustion process. Coke oven gas is a gas fuel produced in the coke oven production process. Its main components are carbon monoxide, hydrogen and methane. During the combustion of coke oven gas, due to high temperature and high pressure conditions, the nitrogen and oxygen in the gas will react to produce nitrogen oxides.
