摘要
Abstract
Refinery sulfur recovery unit plays an important role in the entire production system, and the waste heat boiler superheater is the key component of the device. Because the condition is demanding and complex,the case of superheater elbow cracking was once reported. Through the comprehensive examina-tion and test on the macroscopic test about Elbow cracking parts, thickness measurement, spectrum anal-ysis , metallographic examination, hardness testing and chemical components analysis of stove ash fouling etc, the cause of cracking and the impact of the waste heat boiler superheater and its safe operation was analyzed, then the corresponding prevention and control measure is proposed.关键词
