摘　　要：在化工生产中,间壁式传热设备加热炉出口温度的测量与控制起着十分重要的作用。结合化工自动控制系统的设计经验,并遵循当前相关设计的标准规范,介绍并比较了3种较为常见的加热炉自动调节方案,即单回路调节、串级调节、前馈控制系统调节。提出化工实际生产中,应根据加热炉出口温度是否要求十分严格,外来主要干扰及幅度和频率、炉膛容量、温度被扰等情况选择加热炉的自动调节方案,对加热炉的自动调节方案的研究,为选择最合适的加热炉自动调节方案提供了便利,具有重要的工程实践意义。In the production of chemical industry,it plays a very important role to measurement and control of the outlet-temperature of reheating furnace,which is one of the wall-separates heat-transfer equipment.Based on the design experience of the chemical automaticcontrol system engineering design and the standard specification,three common automaticregulate schemes for reheating furnace were introduced,namely the regulating-scheme of single-loop regulation,cascade-regulation and feedforward control system regulation.In the actual production of chemical industry,it should be based on the degree of strict requirements of the reheating furnace outlet temperature,the external main interference,the amplitude,the frequency,the furnace capacity and the situation of temperature being disturbed,to selecte the automatic adjustment scheme of the reheating furnace,and the automatic control scheme of the reheating furnace,should be studied to select the most suitable reheating furnace for the automatic control designer,which have important engineering practice significance.
