Abstract
A thermal model was established for the study about influence of collapse phenomenon on unburned pulverized coal in COREX melter gasifier. In the model, the ore was simulated by wax, the coke and lump coal were simulated by maize, UPC is simulated by pulverized coal. The results showed that too high blast temperature could lead to collapse in the model, and under normal or collapsing furnace state, UPC is dispersed or aggregated distribution in packed bed. According to this experimental results and the previous research results, the suggestions about COREX were given at last. Keywords: COREX melter gasifier; pulverized coal injection; unburned pulverized coal; physical experiment
