NOx emission in waste heat boiler of the Southeast Electric Power Engineering Department of Xinjiang Zepu Petroleum Base Tower exceeded the standard demand.The numerical simulation method was applied to compare the temperature field
velocity field and final effect of two denitrification methods(SCR method and SNCR method).The results showed that
due to the uneven temperature distribution resulted from the structural limitation of the waste heat boiler
the applicable temperature for SNCR reaction was limited in part areas
so the overall NOx removal was less effective.While the temperature distribution was suitable for the SCR reaction after the boiler additional combustion
