摘　　要：针对华润鲤鱼江有限公司1号机组锅炉爆管停机起动后,汽轮机带负荷能力下降问题,对汽轮机的相关热力参数进行详细的分析,计算调节级组的相对内效率,判断汽轮机带负荷能力下降的原因是通流部分存在故障。Aiming at the reduction of steam turbine load capability of Unit 1 in China Resources Power Hunan Liyujiang Co.. Ltd.. which took place after the restarting of the unit as a result of a boiler tube-bursting failure, this paper analyzes in detail the correlative thermal parameters of the steam turbine, compares the stage group internal efficiency, and concludes that the fault in the flow section is the cause of the problem.

关 键 词：汽轮机 通流部分 相对内效率 故障诊断
