摘要
针对上海电气电站集团生产的600 MW超临界机组,分析给水泵跳闸RB的几个关键控制点,包括稳定燃烧系统保证锅炉不灭火,控制煤水比例保证水冷壁和汽水分离器出口微过热蒸汽不超温,启动备用给水泵,缓解汽动给水泵的负荷压力等。
Aiming at the supercritical power generation units produced by Shanghai Electric Generation Group,several key points about feed pump trip are analyzed,including stabilizing the combustion system to guarantee the boiler combustion,controlling the fuel-to-water ratio to keep proper steam-gas temperature of outlet of the waterwall and steam-water separator,starting the spare feed pump and reducing the load pressure of steam-driver pump etc.
