摘　　要：介绍了炼化装置加热炉主要的控制和联锁方案。加热炉控制主要包括加热炉出口物料温度的控制、防止炉管结焦的控制、炉膛压力控制和烟气氧含量控制。加热炉联锁主要包括加热炉入口物料流量低低联锁、加热炉出口物料温度高高联锁、加热炉燃料气系统联锁、加热炉燃料油系统联锁、烟气温度高高联锁、引风机停机联锁、鼓风机停机联锁和紧急停炉。借助DCS和SIS系统,加热炉的运行实现了自动控制和联锁。The main control and interlock scheme of refine devices heating furnaces are introduced. The control of furnace operating condition mainly include the outlet temperature control of furnace stream, preventing eoking control of tubes, furnace pressure control and oxygen content control of flue gas. The furnace interlocks mainly include flow low-low interlock of inlet stream, temperature high-high interlock of outlet stream, fuel gas system interlock, fuel oil system interlock, temperature high-high interlock of flue gas, halt interlock of induced draft fan, halt interlock of blower and emergency shut-down. Using the DCS and SIS system, automatic control and interlock of furnace operation have come true.
