摘　　要：超临界锅炉机组启动系统设置炉水循环泵,提高了水冷壁的质量流速,热量和介质得到回收,提高了启动速度和效率,而对于超临界锅炉机组在炉水循环泵故障时机组如何操作没有可借鉴的经验。某电厂600MW超临界机组进行无炉水循环泵运行开机时,提出了锅炉的运行方式、注意事项和具体操作过程、要点。Supereritical boiler starting-up system adds boiler water eireulating pumps to improve the mass velocity of medium in water wall. Meanwhile, heat and medium were recycled and starting-up speed as well as efficiency was improved. But it is no reference for supercritical unit startup when boiler water circulation pump was in trouble. The operation mote, specific operation process, and precautions were presented in this paper.
