摘　　要：采用CFB锅炉的机组为减少机组非计划停运次数,或其他类型机组出于安全性考虑,其中一台给水泵汽轮机的汽源采用降低参数后的高排蒸汽,从而降低了机组经济性,但一直未受电厂重视。本文采用耗差理论分析这种运行方式给电厂造成的经济性损失大小,并提供解决问题的方案,以供电厂参考。Because of adoption of reducing the times of CFB boiler unit unplanned shutting down , or other types of units′security reasons , one of feedwater pump turbine steam source takes lower parameters from the high exhaust steam , reducing the unit economy efficiency , and it has not been overlooked by power plants .Based on the consumption difference theory analysis of the operation mode for power plant ′s eco-nomic losses , and provides the solution to solve the problem , which power plant can use for reference .
