Numerical Simulation of Waste Heat Utilization in Coal Gangue Brick Tunnel Kiln

The numerical simulation model of coal gangue brick tunnel kiln system in one coal mine was established to study the waste heat recovery. The gas flow and heat transfer in the coal gangue brick tunnel kiln was studied. The temperature distribution in the coal cangue tunnel kiln was analyzed. 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.
