摘 要:传统模式为电泵启动上水至过临界湿态转干态启动一台汽动给水泵,过完干态后再启动第二台汽动给水泵。经过广东珠海金湾发电有限公司(以下简称"金湾电厂")创新优化后,机组启动给水改为2台汽动给水泵及其前置泵提供,电泵从始至终作为备用不参与运行。The traditional model of the startup water supply for the 600 MW supercritical generating unit is transporting the inflow to the boiler by starting the electric pump,then the first steam driven water feed pump is start up while the water become steam. And after water transit into steam state the second steam driven water feed pump is then start up. By the improvement made by Guangdong Zhuhai Jinwan Power Co. Ltd,the water supply for the generating unit startup is provided by the two steam driven feed pumps and the booster while the electric pump is put in backup state.
