摘　　要：针对国电长源沙市热电厂60MW汽轮机存在第6段抽汽温度高出设计值近5倍的问题,从理论上进行探讨,对介质流量进行复核计算,通过实际跟踪观察分析,最终达到第6段抽汽温度完全恢复正常,为今后国内同型号汽轮机技术改造、设计和运行维护提供了借鉴。The temperature at extraction 6 of 60MW steam turbine in Guodian Changyuansha Thermal Power Plant is 5 times higher than design value. To restore the temperature at Extraction 6 to normal value, theoretical researches were conducted, recheck calculation of media flow were performed, actual tracing and analysis were made. This provides good references for the technical retrofit, design, operation and maintenance of the steam turbine of same type in China.
