介绍了华能东方电厂二期工程3号机组配置1台100%锅炉最大连续蒸发量(boiler maximum continue rate，BMCR)容量汽动给水泵且无电动给水泵的启动特点，计算了机组启动过程全程使用汽动给水泵的节能效果，给出了纯汽动给水泵机组启停的实际情况，可为纯汽动给水泵启动机组设计提供参考。

This paper introduces the start-up characteristics in Dongfang Power Plant Phase II No.3 unit, which is only equipped with steam feed pump for 100% boiler maximum continue rate (BMCR), but with no electric feed pump. The energy-saving effect by using steam pump in the whole process of units’ start-up is calculated, and the practical application of steam pump start-up is presented, which could provide references for the design of units started up only by steam feed pump.
