| 摘 要： | 介绍了在线清焦技术在中国石油乌鲁木齐石化公司1.20Mt/a延迟焦化装置加热炉上应用后对加热炉产生的影响。在线清焦技术的应用有效延长了加热炉的运行时间,但是也对加热炉产生了不利影响,实践证明在线清焦操作会导致加热炉炉管表面热偶脱落、炉管表面氧化剥皮、炉管入口固定螺栓松动、炉管出口法兰螺栓疲劳等不良后果。同时针对在线清焦操作产生的不良影响,提出了一些建议。

| Abstract: | Urumqi petrochemical Co.,CNPC adopts the online decoking technology for its 1.2 Mt/a delayed coking device. This text introduces the situation of heating furnace. The online decoking technology prolongs the furnace running time, but has some adverse effect on the heating furnace, such as thermocouple falling off, tube surface oxidation peeling, tube entrance capebolt loosing，heating furnace outlet flange bolt fatigue. Some suggestions are proposed to solve these damages. |
