Abstract

The mathematical model of combustion for a reactive gas suspension of coal dust in a propane-air mixture is developed. The parametric study of the problem is carried out. The observed burning velocity of the propane-air mixture with an admixture of coal particles is determined. Dependences of the observed burning velocity of the propane-air gas suspension on the equivalence ratio and on the radius of the particles are obtained. It is shown that, the observed burning velocity decreases with an increase in the radius of the particles. On the contrary, with an increase in the radius of the particle, the observed burning velocity increases for high-propane mixtures. Moreover, in the case of high-propane mixtures, the observed burning velocity of the gas suspension can be increased by reducing the mass of the particles. The observed burning velocity for a propane-air mixture with particles is significantly less than that for a mixture without particles.

丙烷气体燃煤燃烧特性

建立了煤尘反应气悬浮液在丙烷-空气混合气中燃烧的数学模型。对该问题进行了参数化研究。测定了掺有煤颗粒的丙烷-空气混合物的燃烧速度。得到了观测到的丙烷-空气气体悬浮液燃烧速度与当量比和颗粒半径的关系。结果表明，燃烧速度随颗粒半径的增大而减小。相反，随着颗粒半径的增加，观察到的高丙烷混合物燃烧速度增加。此外，在高丙烷混合物的情况下，观察到的气体悬浮的燃烧速度可以通过减少颗粒的质量来增加。有颗粒的丙烷-空气混合物的燃烧速度明显小于无颗粒的丙烷-空气混合物的燃烧速度。
