Abstract :
Numerical simulation method has been used to study a 1000 MW double-tangential circular ultra-supercritical boiler combustion characteristic and component distribution by using CFD software in this paper. The component distribution curves are obtained and the analytical results of different working conditions by changing auxiliary air flow rate are given. In general, the change of the auxiliary air ratio has little effect on the NOx distribution in the boiler furnace.
