主反应器进料加热炉是苯加氢系统的重要组成部分,莱钢苯加氢主反应器进料加热炉自控系统采用西门子PLC系统独立自动控制,在对加热炉各工艺参数进行采集的基础上,实现炉膛负压、出口温度调节和点火控制,并且能够在达到联锁条件或出现重大事故情况下紧急停车实现对设备的保护功能。整个系统投资小,性能高,很值得大力推广。 Main reactor feed heating furnace is an important part of benzene hydrogenation system, Laiwu Steel benzene hydrogenation main reactor feed furnace automatic control system using Siemens PLC system independently and automatically control the heating furnace in the acquisition of the various process parameters based On the furnace to achieve negative pressure, outlet temperature adjustment and ignition control, and can achieve the interlock conditions or emergency accident under the circumstances to achieve the protection of equipment. The entire system investment is small, high performance, it is worth vigorously promote.
