Abstract :
The mathematical model of gangue brick tunnel kiln in one coal mine, was established to simulate the heat transfer between brick, air and boiler and to study the waste heat recovery. The temperature distribution in the coal cangue tunnel kiln was studied. Simulation results show that the layout of bricks has certain impact on heat transfer and optimizing the layout of coal cangue brick in the tunnel kiln can improve the efficiency of waste heat utilization. The residence time of brick in tunnel kiln shows important effect on temperature distribution and on brick sintering quality.
