摘　　要：W型火焰锅炉具有火焰长、易于着火稳燃 ,特别适用于低挥发份 ,(Vdaf<10 % )的无烟煤的特点。本文着重介绍了W型炉冷态试验的模拟方法和试验结果 ,探讨了一、二次风 ,上下三次风乏气风的比例变化 ,改变制粉系统运行方式对主气流及炉膛充满度的影响等 。W-flame boiler long flame has a special advantage which is easy stable ignition. So it is suitable for low volatile content anthracite coal. This paper introduced a method of the cold model test and its test result, exploited the effect of changing pulverizing system operating mode on the main stream and the degree of admission in furnace, when the proportion of primary air? secondary air and tertiary air is changed. All the conclusion can be the reference for the design and operation of W-flame boiler.
