摘要

通过对沿海某电厂 30 0MW汽轮机叶片点蚀损伤机理的探讨

指出造成点蚀损伤的主要原因是氯离子腐蚀的结果

对此提出加强给水质量监督

提高蒸汽品质

严格控制蒸汽中氯离子含量等预防措施。

Abstract

Through approaching the mechnism of pitting attack damage for blades of a 300MW steam turbine in a coastal power plant

it is pointed out that the main cause leading to pitting attack damage is the result of chorine ions attack

and some preventive measures

induding strengthening feed - water quality supervision

enhancing the steam quality

and strictly controlling chlorine ions content in the steam etc.

have been given.
