Abstract：The coke descent in the cold model of CDQ cooling chamber was studied by means of tracing method with digital camera. For three different blastcups, the law of coke descent was studied under five conditions of coke charging. The results showed that,elliptical blastcup cross is better than low or high located circular blastcups;coke charge pattern with flat top surface is preferable to that with peakvalley surface, and doublepeak pattern is superior to onepeak one for uniform distribution of coke. Trajectory and average velocity distribution of descending coke are almost independent of whether coke is discharged continuously or not. The blastcups have local effects on the coke descent and have little effects on whether the cokes flow smoothly or not in case that coke bed has enough height.
