Abstract

The invention discloses an ultra-large-load water-cooling low-NOx gas burner. The ultra-large-load water-cooling low-NOx gas burner comprises a high-pressure cooling water circulating assembly, a swirl piece assembly, an incandescent light assembly, a burner barrel body assembly, a central fuel gas gun assembly and an annular fuel gas gun assembly, the central fuel gas gun assembly and the annularfuel gas gun assembly penetrate through the bottom of the burner barrel body assembly and extend into the burner barrel body assembly, the incandescent light assembly extends into the central fuel gas gun assembly from the bottom of the central fuel gas gun assembly and is fixed in the center of the central fuel gas gun assembly, and the swirl piece assembly is arranged in the burner barrel bodyassembly. The ultra-large-load water-cooling low-NOx type gas burner has the advantages that the temperature of an annular flue gas gun, the central fuel gas gun assembly, the burner barrel body assembly, a heating furnace barrel body, a flame center high-temperature region can be effectively reduced, and generation of the NOx can be inhibited.

Description

technical field [0001] The invention belongs to the technical field of burner heating furnaces, in particular to an ultra-large-load water-cooled low-NO x gas burner. Background technique [0002] At present, most of the large petrochemical heating furnaces, large industrial heating furnaces, and large heating furnace burners in power plants are old-fashioned oil-gas mixed combustion burners. Because the furnace temperature is too high, the service life of the burners and devices is short, and the smoke emissions are serious. Exceeding the standard, the "Petroleum Refining Industry Pollutant Discharge Standard" (GB 31570-2015) issued by the State Environmental Protection Administration stipulates that it will be implemented on 2015-07-01, which puts forward higher requirements for flue gas emissions, so the development of a new generation of Water-cooled low-NOx gas burners with super-large loads are imminent. Contents of the invention [0003] The technical problem to b...
