摘　　要：某厂#1锅炉为哈锅600 MW超临界直流锅炉,燃烧器采用三井巴布科克公司的低NOx轴向旋流煤粉燃烧器。运行中部分等离子层煤火检设备发生同类型损坏故障,易引发该层磨煤机跳闸,严重时将影响机组负荷。对该类型故障进行分析并处理,可有效提高磨煤机系统及机组稳定运行。The No.1 boiler of a factory is a 600 MW super-critical boiler made by Harbin Boiler Co., Ltd. with a low NO_x axial swirl pulverized coal burner from Mitsui Babcock. Part of the coal flame probe in operation occurred the same type of damage fault will cause the coal mill trip easily, and cut down the unit load when the situation gets worse.To analyse and treat this type of fault can effectively improve the coal mill system and unit stable running.
