ResumoIn order to improve the size distribution of charged coke in the radial direction of CDQ shaft,the fixed bell type coke distributing equipment was employed.In this paper,the mechanism of coke size segregation in the radial direction of pre-chamber in CDQ shaft was investigated by experiment and numerical analysis.Experimental apparatus was a cold three-dimensional semicircle model for bell-type charging,which was used to study the influences of different kinds of bells and different stock line levels on the distribution of coke size in the pre-chamber.Furthermore,a mathematical model was developed,which is capable of estimating the radial average size distribution as well as the radial deposit distribution of each particle size for multiple size coke with only a few fixed parameters.The calculated results agree well with the experimental data,which proves the reliability of both experimental study and numerical analysis.
