摘　　要：文章通过对热电厂给水泵"电动改汽动"进行节能效益分析,论述了某些200MW以下等级的发电机组,利用小汽轮机驱动给水泵节约了厂用电,降低发电净热耗率,增大主机的出力,降低综合成本煤耗率,使机组的运行经济性得到了明显提高。Analysis of energy-saving benefit of ＂electric to turbine-driven＂ on feed pump in thermal power plant. Carry out in some of the following levels of 200MW generating units, the use of small turbine-driven feed pumps saves the power plant, reduces heat generation net rate and the cost of integrated coal consumption rates, the economy of the unit running has been improved remarkably.

关 键 词：电动给水泵 汽动给水泵 节能 经济性 煤耗率
