摘要
本文描述了双股共轴旋流煤粉燃烧器气体流场的数学模型。应用本模型可以进行燃烧器气体流场的轴向速度分量、切向速度分量及负压的数值计算,而且计算结果与实验值比较吻合。还论述了用本模型计算的一、二次风质量比m_2/m_1对流场的影响,并获得有应用价值的结果。
A mathematical model of flow field for swirtling pulverized coal burner with coaxial doublejets has been studied. The mathematical model can be used for numerical calculations of the axialvelocity, the tangential velocity and the axial pressure. The analytical results are shown to be ingood agreement with the data obtained on the experimental model. The influence of mass ratio m_2/m,on the flow field obtained in the calculations with this mathematical model is also examined.Some results for application have been obtained.
