| Abstract: | Based on the software FLUENT,this paper studied the influence of the excess air coefficient on the combustion and emission process of a 600 MW coal-fired power plant. The numerical simulation results show that,with the increase of the excess air coefficient, temperature of the main combustion area increases, the exhaust temperature of the flue gas reduces,the coal burn-off ratio increases,and the NOx emission increases. |
