摘要
火力发电厂给水系统发生异常,将导致锅炉水冷壁缺水、锅炉干烧等重大事故。对几个给水系统异常造成主燃料跳闸(mainfueltrip,MFT)的典型事故进行分析,并最终通过现场查验资料及排查控制回路等措施,确定了事故原因,为电厂排除了安全运行隐患。
When feedwater system in a coal-fired plant works abnormally, such major accidents as＂water shortage for water-cooled wall＂and＂dry-burning of boiler＂may occur. This paper makes an analysis of the typical main fuel trip faults （MFT） caused by abnormal feedwater system in some power plants, and find out the causes of the accidents through site data check and control loop inspection, and help the power plant to eliminate the hidden troubles in time.
