摘　　要：目前大多数锅炉仍使用蒸汽吹灰器,汽源大多引自主蒸汽系统。由于压力过高,阀门频繁泄漏,严重影响机组安全性、经济性。分析了将汽源改至再热汽系统的优越性,并成功应用于一台300 MW机组,为其他机组的改造提供了借鉴和参考。Many coal-fired boilers use steam soot blower at present, steam source mostly come from main steam system. The valve leaks frequently because the pressure is too high, seriously affect safety and economy of unit. The paper analyse the advantage of steam source changed to reheater steam system, and successfully apply on a 300 MW unit, draw lessons and reference to improvement of the same type unit.
