摘要/Abstract

摘要： 对国内乙烯装置裂解炉对流段的泄漏原因进行分析探讨，认为热应力影响、管内介质的腐蚀、高温氧化腐蚀、烟气露点腐蚀等综合因素，是导致对流段盘管穿孔、开裂的主要原因，并就如何减缓盘管腐蚀提出了预防措施。

关键词: 裂解炉对流段泄漏原因预防措施

Abstract:

This study analyzes the causes of leakage in the convection section coils of cracking furnaces in domestic ethylene plants. It is concluded that combined factors including thermal stress, internal medium effects, high-temperature oxidation corrosion, and flue gas dew point corrosion are the primary causes of the perforation leakage and cracking in convection section coils. Preventive measures to mitigate coil corrosion are also proposed.
