| 摘 要： | 从国产N125-13．24／550／550型汽轮机改造为N137．5—13．24／535／535型冲动式和反动式的2种改造方案出发，针对各种损失的产生机理，从结构参数、热力参数、不均匀流场方面对125MW汽轮机改造后的冲动式、反动式2种方案的调节级进行了比较分析。改造结果表明：冲动式的整体热力性能低于反动式。文中还对优化设计提了建议。

| Abstract: | Beginning with the two retrofitting schemes of indige nous N125 - 13.24/550/550 type steam turbine to be retrofitted to N137.5 - 13.24/535/535 impulse and reaction type steam turbine,in light of various toss mechanism,the control stages of retrofitted tur-bines(impulse tnrbine and reaction turbine) are compared and analyzed based on the structure parameters,thermal parameters and flow non - uniformiry.The retrofitting result shows that,the integral thermal performance of impulse turbine is inferior to that of reaction tur-bine.Furthermore,some suggestions on the design optimization are given. |
