摘要
对Ｗ型火焰煤粉锅炉炉内气－固两相三维流动，传热和气－固两相湍流燃烧进行了全面的数值模拟，计算了在满负荷及５０％负荷２种情况下，Ｗ型火焰煤粉锅炉炉内气－固两相流动、温度场分布和各气相组份浓度场分布，并进一步分析了污染物生成的规律，计算了ＮＯｘ在Ｗ型火焰煤粉锅炉中的分布情况。
Abstract The numerical simulations of gas solid flows,heat transfer and gas particle turbulent combustion have been conducted for a three dimensional,W shaped boiler furnace under different operation conditions for full and 50% load.The gas particle flow,distributions of temperature and concentrations of gaseous constituents,distributions of the rates of heat release,burnout rates of coal particles,and formations of volatiles have been predicted and the NO x formation mechanism is calculated in a post processor routine.
