Coke Size Distribution of BF A Particle size distribution of deadman coke at different positions was shown in Fig. 3. The percentage of feed coke particles larger than 40 mm is almost 85.68 while that of feed coke particles smaller than 25 mm is about 4.54 . However the coke particles smaller than 40 mm were the main component of hearth coke. To verify the effects of particle size distribution and swirl flow intensity on reaction of petroleum coke in combustion furnace a series of numerical simulations have been carried out in this study.
