The curve of relationship between flame speeds and the primaryairratio is got, and when primaryairratio is about 0.
得出了二甲醚火焰传播速度与一次空气系数的关系曲线,并且在一次空气系数约为0。

Selection of the primary and secondary airflow rate, the guide Angle of the blade, the primaryairratio 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。
