Discussion on Related Problems for Pollutant Control of gas Combustion in Industrial Furnace

控制大气污染的重要手段之一是对燃烧过程加以优化控制。文中,在分析产生污染原因的基础上,指出恰当的空气燃气比是保证充分燃烧的关键,并以轧钢加热炉燃烧过程控制为例,简要讨论了复杂燃烧过程的对象特性、可供选择的控制策略和优化的控制算法。成功的工程实践表明,只要对燃烧过程进行优化控制,废气污染是可以消除的。

One of important means in atmospheric pollution control is optimization control for combustion pro- cess. Based on the analysis of produced pollution,it shows that the key of ensuring sufficient combustion is proper ratio between air and gas. In the paper,taking example in which combustion process is controlled in heating fur- nace of rolling. It discusses such as object properties of complicated combustion process,control strategy of ac- ceptable choice and optimal control algorithm. The successful engineering practice shows that if the combustion process is controlled optimizatically then the atmospheric pollution must be reduced.
