在浮悬式燃烧的煤粉锅炉中,燃料的着火和燃烧,火焰中心向水冷壁的传热,以及火焰在炉膛内充满系数等,在很大程度上与燃烧气流在炉内的分布和由此而引起的各个从生涡流区的分布有关。换句话说,炉内空气动力场的分布是否合理,对锅炉的燃烧情况有很大的影响。此外,考虑到在煤种变换时对燃 In floating-suspended pulverized coal boilers, the ignition and combustion of fuel, the heat transfer from the center of the flame to the water wall, and the filling of the flame in the furnace are largely dependent on the distribution of the combustion air in the furnace and This caused by the distribution of each dependent vortex district. In other words, the distribution of furnace aerodynamic field is reasonable, the boiler combustion has a great impact. In addition, taking into account the conversion of coal combustion
