The numerical simulation of the injector of atmospheric gas burner is carried out using software FLUENT, and the relationship between nozzle position and primaryair coefficient is obtained.
采用FLUENT软件对大气式燃气燃烧器的引射器进行数值模拟,得出喷嘴位置与一次空气系数的关系。

Selection of the primary and secondary airflow rate, the guide Angle of the blade, the primaryair ratio as well as the material for manufacture of the burner nozzle are given.
然后介绍了一、二次风速,旋流叶片的导角,一次空气比例系数等参数的选择及制造烧嘴的材料。
