摘　　要：对国电北仑第三发电有限公司(北仑电厂)超超临界1000MW机组汽动给水前置泵的安装位置从距主厂房零米改为17m运转层,并将一体式除氧器抬高至40.5m,提高了机组运行的经济性,改善了厂用电配电条件,减少了设备投资。此改动可为同类型机组的汽动给水前置泵设计、选型提供参考。The installed location of the steam- driven feed- water booster pump for ultra- supercritical 1 000 MW unit in Beilun Power Plant has been changed from elevation 0 m in the main machine hall onto 17 m operating floor,and the integrated mode deaerator Being heigtened to 10.5 m,thereby,the economic efficiency in operation of unit being enhanced, the distribution condition of service power being improved,and the invested capital of equipments being reduced. This modification can provide reference for design and type ,selection of steam - driven feed - water booster pump used for similar type of unit.
