摘要： 华电新疆发电有限公司乌鲁木齐热电厂#1，#2汽轮机在开、停机时采用30% 额定容量的电动给水泵为锅炉上水。机组在100MW时，存在着机组停下来升负荷、冲给水泵汽轮机的问题，不但影响了机组加负荷，还增加了厂用电率。采用备用汽源将给水泵汽轮机冲动，用汽动给水泵代替电动给水泵上水的改进方案，解决了负荷受限问题且节约了厂用电，经济效益明显。

Abstract: For the startup and shutdown process of turbine No.1 and No.2 in Urumqi Thermal Power Plant of Huadian Xinjiang Power Generation Company Limited, the electrically driven feed pump was adopted for boiler water feeding, its feed ability is 30% rated capacity of the boiler. When the units load reached 100MW, the unit load up had to be stopped for rolling the turbofeed pump, this would not only delay the units load up, but also increase the house service consumption rate. Application of an improved scheme, in which the turbofeed pump rolled by a standby steam source is used to feed the boiler instead of the electrically driven feed pump, solved the problem of load up limitation and saved the house service consumption rate, favorable economical benefits have been obtained.

Key words: electrically driven feed pump, turbo-feed pump, auxiliary steam header, water feeding, improved scheme
