国产引进型 300MW 汽轮机的出力问题及在妈湾电厂 2 台机组上的改善

阐述了我国自８０年代初引进技术并在９０年代普及应用的国产引进型３００ＭＷ汽轮机的概况及所遇到的主要问题。结合妈湾电厂１号和２号汽轮机的大修改造，介绍了对国产引进型３００ＭＷ汽轮机出力改善的典型措施及主要试验结果。作者认为，今后改型工作应着重于提高汽轮机的效率。

?0 In this paper, the author presents the technology licensed by our country since 80s, its popularized and improved in 90s of domestic licensed 300MW steam turbine and its encountered principal questions. And with the overhaul and improvement on the steam turbines No.1 and No.2 of the Mawan Power Plant, the author presents also the typical measures and principal experimental results on the output improvement of the domestic licensed 300MW steam turbine. The author thinks that the type improvement working must be on key point of the steam turbine efficiency increasing. Fig1, tables 5 and refs 2.
