循环流化床锅炉风帽漏渣原因分析与治理

Slag Leakage Causing Analysis & Management on Funnel Cap of Circulating Fluidized Bed Boiler

对神华亿利电厂循环流化床锅炉风帽漏渣原因进行了分析,提出了漏渣主要原因是风帽结构不合理的结论,通过风帽结构改造及布置优化、一次等压风室入风管段改造、运行参数优化调整控制等治理措施,彻底解决了风帽漏渣问题,提高了机组安全经济运行性能。

Analyze the cause on cinder leakage to the funnel caps in CFB boiler of Shenhua Yili Energy CO,LTD,.,and put forward that the mian cause on cinder leakage is unreasonable of the funnel cap＇ s structure,so to change of strcuture and layout optimization of the funnel cap, the pipe of air primary chamber and optimal adjustment of operational parameter, Cinder leakage to the funnel caps have been solevde completely,develop the security and the reconstruction in CFB boiler.
