- Abstract
The 2-D numerical simulation of the particle motion and combustion behavior in the raceway has been done to analyze the gas-flow field, pressure field, temperature field, distribution of gas composition, as well as the effect of coke mass-flow rate, and blowing gas temperature on the maximum temperature in the raceway zone. The results show that the temperature in the cavity reaches the maximum in the upper part of the cavity region, and the maximum value is above 3000 K. During the combustion process, the concentration of O2 decreases, and the concentration of CO increases. The highest CO content in the gas leaving the raceway zone and entering the coke bed is about 0.95, while the lowest O2 content is 0.05.
