摘要
本文研究了Ｗ型火焰煤粉锅炉炉内传热过程的数值模拟计算方法．用蒙特卡洛法计算辐射换热，用差分法计算对流换热及导热．利用这一方法计算了３００ＭＷＷ型火焰锅炉炉内的温度分布，取得了比较满意的结果．另外，本文还对有关蒙特卡洛法的几个问题进行了研究．
The mathematical simulation method is mentioned in this paper of calculating the heat transfer in a furnace of 300MW W-shape pulvenzed coal boiler. According to this method, the exchanged radiative thermal energy is calculated by Monte Carlo method, meanuhile, the calculation of convection and conduction in the furnace is performed by definite difference method. By using this method, the satisfied temperature distribution in the furnace is figured out. In the end, several problems about Monte Carlo method is alsodiscussed in this paper.
