一、设计内容

炼油装置加热炉（常减压加热炉为例）
二、设计要求：
设计方案说明
1、常减压装置分常压炉和减压炉，两个加热炉控制方案一样，下面以常减压装置加热炉为例介绍控制方案及连锁系统：
常压炉炉膛温度控制方案：以原料出加热炉温度TE-2005A/B（其中一支备用，由DCS软开关选择用那一路控制）为主回路PID为TIC-2005，然后取四点炉膛温度TI-2004A—D（四个温度）的平均值作为副回路，控制进加热炉燃料油流量阀或者燃料气流量阀（由DCS软开关选择，看工艺用哪种介质而定）。
2、常减压常压炉连锁说明
（1）鼓风机连锁：鼓风机停运输出连锁常压炉快开XV2001A/B/C/D/E/F/G/H  打开 和引风机停运。
引风机连锁 ：通往烟囱的挡板XV4001打开， 通往预热器的挡板XV4002关闭。
（2）设备选型说明并列仪表设备清单
DCS系统选用和利时MACSV 6系统SM系列。
