分析了C5 0 90 / 13型汽轮机低压缸叶片断裂事故的原因

提出了更换第 13级叶片、低压缸通流部分改进、整机通流部分改进几种解决对策

并从改造费用、经济性方面做了比较。为 5 0MW机组的改造提供了一定的依据和经验。

The causes of blade breakage in low-pressure cylinder of a C50-90/13 type steam turbine have been analysed

several resolving countermeasures

such as replacing blades of thirteenth grade

retrofitting flow passage of low-pressure cylinder

and retrofitting flow passage of the entire turbine etc. are put forward

and a comparison from aspects of retrofit expenses and economic issues being made

providing a certain basis and experience for retrofitting 50MW units in the future.
