增加吹灰蒸汽作为辅助蒸汽系统备用汽源的改造

Retrofitting by Adding Boiler Soot-blowing Steam as Reserved Steam Source for Auxiliary Steam System

介绍了华能岳阳电厂进口机组辅助蒸汽系统为提供紧急备用蒸汽的小容量发电机组退役后 ,原锅炉仍作为进口机组的启动锅炉使用 ,已不能满足生产安全和经济的需要 ,所采取的增加吹灰蒸汽作为辅助蒸汽系统备用汽源的改造 ,方案简单、改动方便、费用低 。

In HIPDC Yueyang Power Plant, a small capacity generating unit was used to provide the auxiliary steam for the imported unit as an emergency backup steam source. When this small unit is out of service, its boiler, used as a startup boiler for the imported unit, can not meet the economic and safe operation requirements. This issue can be properly resolved by a retrofitting that adds more boiler soot blowing steam as backup steam source for the auxiliary steam system. This scheme is simple, easy to implement, and not costly.
