摘　　要：分析循环流化床锅炉运行中出现的高温再热器、二级过热器爆管和给煤系统旋转给料阀经常堵煤等问题。对高温再热器、二级过热器采用减少受热面等方式,对给煤系统采取拆除旋转给料阀、增加密封风等技术措施后,提高了锅炉运行安全性。井提出循环流化床锅炉在系统设计、建设和运行时应注意的问题。The causes of SH and RH tube explosion and coal feed system jamming in the operating CFBB are analyzed. After technical measures to retrofit SH, RH and coal feed system had been taken. the operating safety of CFBB was improved ever since. And suggestions on design, construction and operation of CFBB systems are put forward in the paper.
