2950 t/h tangential-fired boiler is manufactured for the 1000MWe capacity super critical utility units, which employs the low NOx concentric firing system (LNCFS) and the deep air staged technology for reduce the NOx emission. In this work, the comparison of two schemes of separated over-fire-air employment was conducted using the numerical simulation method, the flow field, temperature distribution, oxygen concentration in the furnace and NOx emission were obtained. The numerical results showed that the combustion system employed in the 2950 t/h tangential-fired boiler had good performance on the NOx reduction, carbon burnout. The NOx emission can be reduced to less than 300 mg/Nm^3 when the Shenhua coal was burned.
