ABSTRACT: The unit of Power Plant start-stop operations without electrically driven feedwater pump is the development direction in the future. many power plants have achieved  that inland. realizing the subject  can reduce the quantity of power at start-stop operation,which accord with energy conservation and technological progress policy. For HanFeng  power plant which have two service units of 660 MW without this design. After much research and development, we have completed the project, and achieved the desired effect.
KEY WORD:  in service units; without electrically driven feed water pump start; turbine-driven feed water pump steam supply; Energy saving
摘要：无电泵启停机组的设计是火电机组今后发展方向，国内已有多家电厂实现，该课题实现后可以减少机组启停时外购电量，符合节能和技术进步政策。对于邯峰电厂两台660MW无此设计的在役机组，我们经过大量试验和必要的技术改造，顺利完成该课题，达到了预期效果。

1、设备系统情况：
邯峰电厂每台机组配备两台小汽轮机驱动的锅炉给水泵和一台电动给水泵。电泵电机功率7000KW，机组启停用电动给水泵上水，并可承担35%的负荷；正常运行中用两台50%出力的汽泵保证锅炉给水。
汽动给水泵的小汽机供汽方式是：正常运行中由A5抽汽供汽，抽汽压力不足时由冷再汽源补充，用辅助蒸汽进行暖小机与调试汽泵。
