The mechanism of coke size segregation in the radial direction of pre-chamber in coke dry quenching(CDQ)shaft was investigated by experiment and numerical analysis.The 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 radial dis- tribution of coke size in the radial direction of a pre-chamber.A mathematical model was used,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 a few fixed parameters.The calculated results agree well with the experimental data,which proves the reliability of both experimental study and numerical analysis.
