摘　　要：以军粮城发电厂200 MW机组配套2台液力耦合器驱动的全容量电动给水泵为例,论证如从汽机本体四抽抽出部分蒸汽驱动小汽轮机,以小汽轮机驱动给水泵来代替电机驱动,可节约厂用耗电。并根据耗汽量的增加,其发电煤耗率也增加的实际情况,对电泵改汽泵后对煤耗的影响进行了细致的计算分析。Taking economy estimation of military electric power 200 MW unit all capacity motor-driven pump changed to steam feed pump as an example to analyse methods of energy saving. According to the increase of steam consumption and coal consumption rate, particular caculation analysis after motor-driven pump reconstruction is proposed.
