Technical Field

[0001] The utility model relates to the technical field of natural gas low-nitrogen burners, in particular to a natural gas low-nitrogen burner for a boiler. Background Art

[0002] A low-nitrogen burner is a burner specifically designed to reduce the emission of nitrogen oxides produced during the combustion process. Nitrogen oxides are pollutants that are harmful to the environment and human health, and their emission is of great significance to the control of air quality and air pollution.

[0003] When using natural gas low-nitrogen combustion in a boiler, it is generally necessary to filter the gas entering the burner. This is because natural gas may contain impurities, particulate matter or other impurities that may damage the burner or affect the combustion effect. Filtering can remove these impurities to ensure the normal operation and efficient combustion of the burner.

[0004] The filtering equipment in the existing low-nitrogen burner is usually fixed, so after the filtering equipment is used for a long time, the filtering will be poor and need to be replaced. At present, when replacing the filtering equipment, the entire equipment needs to be disassembled. This method is not only time-consuming and labor-intensive, but also frequent disassembly will cause damage to other parts. To address this problem, we have proposed a natural gas low-nitrogen burner for boilers. Summary of the invention
