600MW机组无辅助汽源热态启动方案的探索与实践

Research and Practice for 600MW Unit Hot Start Program without Auxiliary Steam Source

单机600MW超临界机组,在没有辅助汽源的情况下,积极探索了一套有针对性的启动方案。通过分析实践过程中存在的问题,提出防范措施,能够达到机组热态的快速启动,既节约了生产成本,又缩短了启动时间,取得了良好的经济效益和社会效益,在国内同类型机组中具有较好的借鉴意义。

Single 600MW supercritical unit,in the absence of auxiliary steam source cases,we actively explored a targeted launch program.By analyzing the problem in practice,with preventive measures,the program achieved the rapid unit hot start,both saved production cost and shortened the startup time,and achieved good economic and social benefits.It has good reference value for the same type unit in our country.
