摘要
针对一台200 MW火力发电机组电动给水泵突然失电后引起直流锅炉灭火、机组停机事故,从给水泵及直流锅炉的水动力特性方面着手,分析了事故过程和事故原因,并提出了相应的安全技术防范措施,以确保机组安全稳定运行。
To find the causes leading to flameout of once-through boiler and subsequent unit shutdown after sudden power loss of the feed water pump of a 200 MW thermal power unit, an analysis was carried out to the failure process from the perspective of hydrodynamic characteristics of the feed water pump and once-through boiler, based on which corresponding countermeasures were proposed, so as to ensure safe operation of the unit.
