摘要
利用FLUENT软件研究了过量空气系数对某电厂600 MW负荷的燃烧及排放过程的影响。数值模拟结果表明,过量空气系数增大,主燃区温度升高,炉膛出口烟温有所降低,煤粉燃尽率提高,NOx排放上升。
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.
