摘要
对加氢加热炉高温超负荷运行产生的炉管过热结焦进行了分析,并对炉管进行了检测,发现炉管硬度严重超标。为保证加热炉安全运行,提出了安装炉管管壁热电偶、强化炉管烧焦等对策。
Through the analysis of heater tube coked by overheat because of hydrogenation heater operating at high—temperature and over load and through detection on the heater tube, find that the rigidity of heater tube is serious be- yond standard—specification.To ensure the heater for safe operation,a thermocouple is pro- posed to install on the tube wall to protect the heater tube from coking.
