220 MW机组凝结水泵出力不足改造

Condensate Pump Output Insufficient Retrofit in 220 MW Unit

凝结水泵是电厂中的重要辅助设备,保证其正常出力,对机组的稳定运行十分重要。针对某电厂220MW机组凝结水泵在调试阶段几次启动时出力数据进行了讨论,确定1号机组凝结水泵出力不足,在所采集实时运行数据的基础上,结合原设计参数及现场情况,对该电厂凝结水泵出力不足问题进行了改造,消除了凝结水泵出力不足的设备缺陷,提高了凝结水泵运行的安全性和经济性。

Condensate pump is an important auxiliary equipment of power plant;it is important to the stable running of the units. The paper discussed the condensate pumps running date during the integral startup of 220 MW unit;the running date showed the condensate pumps unit output was insuffi-cient of NO. 1. Based on the real-time data collected from power plants, design data and situation of the site, we retrofit the system for the condensation water pumps output insufficient, eliminate the shortage of equipments and improve the security and economy in condensate pump operation.
