摘要
Abstract
In a gas turbine power plant,the high pressure evaporator of a heat recovery steam generator(HRSG)experienced multiple leakage failures.To identify the root cause,metallographic analysis was performed on the leaked tubes,and a comprehensive assessment was carried out in combination with the system design and operating conditions.The results indicate that the leakage of the high pressure evaporator was primarily caused by corrosion fa-tigue resulting from the combined effects of multiple factors.Based on this failure mecha-nism,a series of targeted improvement measures were implemented,which ultimately resolved the leakage problem.This case provides a useful reference for the fault diagnosis of similar equipment.关键词
