摘要：

摘要：电动给水泵功率较大，降低其使用率可有效降低厂用电率。通过对机组增加一路辅助汽源，可扩大汽动给水泵的工作范围，在机组启动和停止阶段替代电动给水泵，从而减少厂用电；同时，在事故处理中可以减少机组非计划停运时间。某300MW火电机组实践证明，辅助汽源引入手段可有效减少电动给水泵电耗，提高机组运行可靠性。

Abstract:

Abstract:The power of the electric feed pump is larger, and to reduce the usage rate of the electric feed pump can reduce the station service power consumption rate. One auxiliary steam source was added for the turbofeed pump, and the working range of the turbofeed pump was enlarged. Then the turbofeed pump can instead of the electric feed pump during unit startup and shutdown processes, and the auxiliary power consumption was reduced. At the same time, in accident treatment, the unplanned outage time can be reduced. It was verified by the practice of a 300MW thermal power unit that to add the auxiliary steam source can reduce the power consumption of the electric feed pump effectively and can improve the unit operation reliability.

Key words: Keywords:electric feed pump, turbofeed pump, recirculation valve, 300MW thermal power unit
