| 摘 要： | 在冷态模型流场内，考虑气流对粉煤颗粒的气动阻力，建立其运动微分方程式。通过计算，得到九种粒径的颗粒在流场中的运动轨迹、停留时间、着膜位置和气－固相相对速度与该燃烧器几何参数和气动参数的关系，为燃烧器的深入研究提出了建议。

| Abstract: | A kinematic differential equation of pulverized coal is established in this paper,taking the aerodynamic resistence of the flow into accoount.By calculating nine different diameter pulverized coal,the relation of the kinematic locus,stay time,the relative velocity of gas-solid phase and the geometrical and aerodynamic parameters of the burner are gained.And a proposal for further study of the burner is put forward. |
