摘　　要：火炬系统是石化企业重要的装置,火炬自动控制系统是火炬系统的核心。以丙烷脱氢装置(PDH)火炬系统为例,介绍了PDH火炬系统点火控制、液位控制、分级燃烧控制等方案,具体分析了封闭式地面火炬的控制方案,阐述和分析了火炬控制系统的功能,并介绍了火炬控制系统的硬件设计、控制逻辑程序设计、HMI设计。现场应用情况表明,该控制系统具有自动化程度高,安全可靠,可维护性强等优点。Flare system is an very important facility for petrochemical enterprises. The flare automatic control system is the core of flare system. Based on the flare system for propane dehydrogenation(PDH) plant, the ignition control, liquid level control and cascade burning control plans of PDH flare system are introduced. The control scheme of the closed ground flare is analyzed, the functions of flare control system is expounded and analyzed, and the hardware design, control logic program design and HMI design of flare control system are introduced. application shows that control system has the advantages of high automation, safety and reliability, and strong maintainability etc.
