| 摘 要： | 本文借助CFD技术对低热值气体在旋流燃烧器内的燃烧过程进行数值模拟。通过改变旋流燃烧器的导流叶片安装角度、燃料-空气预热温度、过量空气系数等参数,对热值为4.2 MJ/m3的低热值气体的多个冷热态工况进行数值计算,研究燃烧器结构参数及着火条件对燃烧过程的影响。本文为低热值气体燃料的利用以及相关燃烧器具的开发提供了参考依据。

| Abstract: | This paper simulates the combustion process of low calorific value gas in the swirl burner with the help of CFD software.By changing the angle of guide vanes,preheating temperature,excess air ratio,this paper simulates the conditions of several cold and hot state of the low calorific value fuel with 4.2 MJ/m3 calorific value,studies the influences of structure parameters and ignition conditions on the combustion process.The research provides a reference for the use of low calorific value gas fuel and the development of the related burner. |
