摘　　要：国内火电机组引进的660MW超超临界锅炉技术,锅炉整体运行效果良好。但近几年,部分660MW超超临界电厂反馈存在再热蒸汽欠温问题,再热蒸汽汽温达不到额定值,低负荷工况下该问题更为明显,造成锅炉及机组效率偏低,对电厂的经济效益造成极大影响。The domesticthermal Power plant applied imported 660MW ultra super-critical boilertechnologyoperates well.However in recent years,some 660MW ultra super-critical plant exists the insufficient reheater temperatureproblem,the reheater temperature couldn*t reach to rated value.It is more obvious under low load conditions.It results to the low boiler efficiency and great influence on the economic benefit.
