The burner consists of a central column cyclone, observation hole, fire detection and control system, pilot lamp, simplified tube, gas gun (composed of inner and outer guns), air regulating mechanism, flue gas circulation system, etc. The burner adopts advanced technologies such as air classification, fuel classification, rich lean combustion, and flue gas recirculation at home and abroad, which can form a vortex flame in the furnace, reduce the flame length and flame center temperature, and greatly suppress the generation of NOx through segmented combustion, thereby reducing the NOx emissions in the flue gas.
