| Abstract: | A 3D numerical simulation study was performed to simulate the physical and chemical process in dual combustion and denitration (DD) process precalciner which is widely used in cement production. The coupling relation of mass and energy between coal combustion and calcium carbonate decomposition was studied and analyzed deeply. A calcium carbonate decomposition model applicable for industrial analysis was developed based on the previous work, and the process of mass and heat transfer was analyzed deeply. Results of numerical simulation provide theory information for industrial analysis of the coupling relation between coal combustion and calcium carbonate decomposition. |
