Abstract The air channels of the burner is designed as constrictionzoom structure which can suction exhausted gas by pressure swing, as a result, lowoxygen combustion is achieved and structure of normal burner is optimized. By using Fluent, numerical simulation of this optimization is calculated. The results show that optimized burner can enlarge the volume of the flame. Mean temperature of furnace rises while the number of partial high temperature zones decreases. Nitrogen oxides fall sharply, which reduces pollutant emissions apparently.
