摘　　要：低压大气式燃烧器是一种普遍采用的民用燃烧器。引射器是此类燃烧器的重要组成部分,完成燃气和空气的预混。通过分析引射器的结构特点及工作原理,选取常见的1型引射器,建立流体力学模型。利用FLuent软件模拟引射器的工作过程,得到引射器内部的混合气体流场,为引射器的设计和改进提供参考。Low pressure atmospheric burner is a widely used civil burner.The ejector is an important part of this kind of burner,which completes the premixing of gas and air.Through the analysis of the structure and working principle of the ejector,type1 ejector is commonly selected,and a hydrodynamic model is established.The FLuent software is used to simulate the working process of the ejector,and the mixed gas flow field inside the ejector is obtained,which provides a reference for the design and improvement of the ejector.
