Theoretical and Numerical Analysis of Waste Heat Utilization Device for Coal Gangue Brick Tunnel Kiln

摘要

This paper studies the waste heat utilization device for the coal gangue brick tunnel kiln. The heat transfer mode of the waste heat utilization device is different form the past. It recovers the physical sensible heat of the high-temperature brick. This paper builds a theoretical model to analyze the situations of the cooling section of the coal gangue brick tunnel kiln, and analyzes the temperature field numerically. The results show that the distance form the waste heat utilization device to the sintering section of the coal gangue brick tunnel kiln must be more than 2m.
