Abstract:
Based on the Eulerian multiphase flow model, the three-dimensional numerical model of gas-solid flow and roasting process coupling in pelletizing shaft furnace is established. The gas phases is modeled with the k-e turbulent model; the particle is modeled with the kinetic theory of the granular flow model; the chemical reaction is modeled with the oxidation kinetics model. The roasting processes for different operating conditions are simulated to discuss the effects of the operating parameters on the temperature of the furnace and the yield of Fe2O3. The results show that there are maximum requirement values for the flue gas temperature entering the shaft furnace, the amount of flue gas entering the shaft furnace and the amount of cold air entering the shaft furnace, and the values are 1400K,65.6t/h, 7.8×104m3/h, respectively. Before reaching the maximum values, the temperature of the furnace and the yield of Fe2O3 increases with the increase of the flue gas temperature, the amount of flue gas and the amount of cold air. In excess of the maximum values, the temperature of the furnace decreases with the increase of the flue gas temperature and the amount of cold air, and has little changes with the increase of the amount of flue gas. The yield of Fe2O3 decreases with the increase of the flue gas temperature and the amount of flue gas, and increases with the increase of the amount of cold air.
