摘　　要：工业燃烧过程控制是工业生产中的重要领域,其任务之一就是控制锅炉产生的蒸汽压力满足要求。针对这一过程,设计了包含蒸汽压力串级控制系统、燃料空气流量比值控制系统、炉膛负压前馈-反馈控制系统的工业燃烧过程控制系统,在完成对锅炉产生蒸汽压力控制的同时,兼顾对锅炉燃料量、送风量和炉膛负压的控制。实际以PLC作为控制器,通过硬件设计、PLC程序设计、建立MCGS实时监控界面、利用MATLAB仿真软件进行仿真控制四个步骤,完成了工业燃烧控制系统的控制任务。该系统达到了相应的技术指标要求,并能安全、稳定、低能耗运行。Industrial combustion process control is an important field in industrial production.One of its tasks is to regulate the steam pressure generated by the boiler to meet the requirements.For this process,an industrial combustion process control system including a steam pressure cascade control system,a fuel-air flow ratio control system,and a furnace negative pressure feedforward-feedback control system was designed to control the steam pressure generated by the boiler while taking into account the control of boiler fuel volume,air supply volume and furnace negative pressure.Practically,PLC is used to play the role of controller in the system through hardware design,PLC program design,establishment of MCGS real-time monitoring interface,and simulation control with MATLAB.The system meets the requirements of corresponding technical indicators,and can operate safely and stably with low energy consumption.
