Numerical Simulation of optimization of waste heat recovery equipment in coal gangue brick tunnel kiln
Abstract：The numerical simulation model of coal gangue brick tunnel kiln system in one coal mine was established to study the waste heat recovery.The heat transfer in the coal gangue brick tunnel kiln was studied.The effect of location of the waste heat recovery equipment on the temperature distribution in the tunnel kiln was studied by placing the equipment at combustion section,cooling section and joint of combustion section and cooling section respectively.The simulation results show that location of heat equipment in the tunnel has a certain degree influence on kiln temperature distribution,especially on the the combustion paragraph temperature.In order to ensure the calcined quality of coal gangue brick,consideration should be given access location of the hot combustion equipment brick temperature The effect of the waste heat recovery equipment on the temperature of the coal gangue brick should be considered.
