摘要
为完善引射式预混燃烧器中引射器的操作特性,对工况参数进行数值模拟分析,分别研究工作流体速度v、被引射压力P_(2)和出口压力P_(3)对引射器引射特性的影响。模拟结果显示,对预混燃烧器中引射器的运行优化,有助于提高燃烧效率。
In order to improve the operation characteristics of ejector in ejector premixed burner,the influence of working fluid velocity v,ejector pressure P_(2)and outlet pressure P_(3)on ejector characteristics were studied by numerical simulation analysis of operating parameters.The simulation results show that optimizing the operation of the ejector in the premixed burner helps to improve the combustion efficiency.
