摘　　要：针对原 2 0 0MW汽轮机中压缸静叶叶型损失偏大 ,动静匹配不佳造成攻角过大的问题 ,采用后部加载叶型并选用新的造型方法对静叶进行了技术改造。实验结果表明 ,改型后的静叶叶型损失下降 ,和动叶的匹配得到改善 ,2 0To reduce profile loss and attack angle, rear-loaded profile and new stator blading method are applied to stators in 200MW steam turbine mid-pressure cylinder. Experiment results show that new stators with less profile losses have reduced attack angle and then improved matching between stators and rotors.
