摘要: 阳城6×350 MW机组“W”型火焰锅炉因煤质原因导致炉内结焦、掉焦现象严重,多次引起炉膛压力保护动作触发主燃料跳闸,严重影响了机组的安全稳定运行。通过对炉膛压力保护动作曲线以及对炉膛压力取样系统、保护系统和调节系统存在的问题进行分析研究,介绍了结合现场实际条件制定的优化措施以及措施实施后取得的效果,对同类型锅炉解决相似问题有一定的借鉴作用。

Abstract: The problems of furnace coking and coke falling are serious in the“W”-flame boilers of the six 350-MW units of Yangcheng Power Plant due to the coal quality and have caused the tripping of main fuel by furnace pressure protection repeatedly, which seriously affects the safe and stable operation of the units. The analysis on the operation curves of the furnace pressure protection and the problems in the furnace pressure sampling system, protection system and control system is conducted and solutions are proposed based on the actual field conditions. The effectiveness of the solutions is proven and can be used as the reference to similar problems.

Key words: “W”-flame boiler, coking, furnace pressure protection, optimization strategy
