摘　　要：根据某电厂S109FA燃气-蒸汽联合循环机组D10型汽轮机的结构特点,对比分析各个试验期的性能数据,发现该机组经过10多年运行性能下降明显。结合机组检修发现的问题,诊断D10型汽轮机热力性能下降的主要原因是高压缸动、静叶部分受损和通流部分结垢导致通流面积减小,提出了相应的预防措施及相关建议,该性能分析结果可为国内同类机组的优化运行提供参考。Based on the structure feature of a power plant 's S109 FA gas-steam combined cycle unit D10 steam turbine,the performance data of different test period was compared. It was indicated that the unit performance lost in the past 10 years.Combined with the problems found during maintenance,the causes of performance loss were indicated as high pressure cylinder vane damage and flow part scaling. Prevention measurements and suggestion was indicated. This performance analysis could be referred for performance improvement projects of similar units.
