摘要：

中科（广东）炼化有限公司800 kt/a蒸汽裂解装置裂解炉建成投产3个月，在停炉烧焦后检查炉膛衬里时，发现返炉膛烧焦口上方部分衬里耐火砖表层出现龟裂和剥离，并呈紫红色。对剥落耐火砖进行采样及全组分分析，发现耐火砖掺进了异常组分，从工艺流程找到异常组分来源，并提出对策。

Abstract:

Three months after the cracking furnace of 800 kt/a steam cracking unit was built and put into operation, the furnace lining was inspected after the furnace was shut down for coke burning. It was found that the surface layer of some lining refractory bricks above the coke burning mouth of the furnace was cracked and peeled, which was purple red. Based on the analysis of the whole components of the peeled refractory brick, it is found that the abnormal components are added into the refractory brick. The source of the abnormal components is found from the process flow, and the countermeasures are put forward.
