高炉热风炉燃烧输入输出数学模型的应用

 采用机理模型与辨识模型相结合的方法构成热风炉控制模型，研究热风炉燃烧过程中输入输出的瞬时变化规律。在新建立的模型中，首先建立机理模型，用来计算热风炉燃烧过程中的输入输出值，利用实际生产数据确定辩识模型，然后综合应用2种模型形成新的输入输出模型，仿真分析2种模型的输入输出规律。对比研究表明，2种模型综合应用能够更好地操控热风炉燃烧过程，阻尼外部扰动，保障合理的空燃比，这是热风炉高温长寿与节能环保的有效方法。

Application of mathematical model of combustion input and output of hot blast stove

In the current study,a stove control model was proposed based on the mechanism model and the identifica-tion model to study the variation of the instantaneous input and output in the stove combustion process. In the present model,the mechanism model was first established to calculate the input and output during the combustion operation of stove,then the identification model was developed and verified using plant data,finally both models were then compre-hensively applied to generate a new input and output model. Simulation analyses were performed to investigate the input-output relationships in these three models. Results show that the comprehensive application of the first two models can better control the stove combustion process,damp the disturbance slowly to achieve full combustion,realize the longev-ity under high air temperature,and thus make the hot blast stove more energy-efficient and environmentally friendly.
