摘　　要：本文针对某钢铁厂锅炉燃烧中风煤配比不合理的情况,提出了基于热效在线计算通过对燃烧过程简介,从空气量、风速和含氧量三个方面进行配风优化的数学建模,以实现对煤粉锅炉燃烧的优化控制。仿真结果表明,炉膛温度稳定性能和动态性能都得到了很大的改善。因此本文提出的锅炉配风方案可以满足钢铁厂要求,为企业创造了一定的经济效益和社会效益。Aiming at the unreasonable coal ratio in the combustion of a boiler in a steel plant,this paper proposes a mathematical model for air distribution optimization from the three aspects of air volume,wind speed and oxygen content based on the introduction of the combustion process based on the online calculation of thermal efficiency.In order to achieve optimal control of pulverized coal boiler combustion.Simulation results show that the temperature stability and dynamic performance of the furnace have been greatly improved.Therefore,the boiler air distribution scheme proposed in this paper can meet the requirements of steel plants and create certain economic and social benefits for enterprises.
