摘要
以富氧燃烧技术的可行性、运行的安全性、装备的可用性以及系统的可靠性等方面为基点,探讨并提出了富氧燃烧电站锅炉风烟燃烧过程控制方案的若干设计原则.结果表明:富氧燃烧系统与空气燃烧系统运行控制的差异主要表现在锅炉侧风烟子系统和燃烧子系统的控制,并涉及到几个主要过程:模式切换过程、供氧配风过程、燃烧调控过程、风烟循环过程和排烟压缩过程;所提出的控制原则和策略能够切实满足系统涉及的各个工艺过程的运行控制需要.
Based on technical feasibility,operational safety,equipment usability and system reliability of the oxy-fuel combustion technology,several design criteria were discussed and set up for control programs of the air/gas circulation and combustion subsystem in an oxy-fuel boiler.Results show that the main difference between oxy-fuel and traditional air combustion system lies in the control of boiler side air/gas circulation subsystem and burning subsystem,including following major processes:mode switching,oxygen supply and air distribution,combustion control,air/gas circulation as well as gas discharge and com-pression,etc.The control principles and strategies proposed can satisfy the control requirements of every process in relevant systems.
