摘要
阐述了对300MW汽轮机组中压缸典型级进行的优化及优化设计前后的环形叶栅对比吹风试验。试验结果证明,优化设计是成功的。优化设计弯曲叶片总损失比原设计直叶分流叶栅总损失下降幅度为32.3%。
The paper introduces improvement for the typical s tage of 300MW IP Turbine and the wind tunnel contradistinctive tests for annulus nozzle, the experiment result proves that the optimized design is successful. T he total loss in the compound leaned nozzle blade compared to the original desig ned straight diffluent blade is decreased by 32.3%?
