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 economic losses,and provides the solution to solve the problem,which power plant can use for reference.
