摘要
介绍了中国石化齐鲁分公司炼油厂重油催化裂化装置中烟机在计划维修中发现存在的结垢和磨损问题。分析了烟机结垢和磨损的原因,指出催化剂细粉颗粒是结垢的根本原因,粉尘浓度高是磨损的直接原因。结合多年操作经验和检修中发现的问题,提出了预防烟机结垢和磨损的相关措施。
This article describes the scale buildup and abrasion problems identified in the flue gas turbine of the heavy oil FCC unit of the Refinery of SINOPEC Qilu Company during a scheduled overhaul.The article analyzes the causes of the scale buildup and abrasion and concludes that fine particles of catalyst are the root cause of the scale buildup and that high-concentration soot is the immediate cause of the abrasion. The authors propose some measures for preventing scale buildup and abrasion of flue gas turbines ,particularly specific to the problems detected during the overhaul ,based on their years of experience in operating the turbines.
