双通道隧道窑改造热工理论分析--不同厚度窑墙的隧道窑内综合传热研究

摘要

This paper researches one-meter firing zone with highest temperature of a reformed double-tunnel kiln from three aspects as follows: airflow condition in the firing zone, heat exchange in the kiln, heat transferring amount through the kiln wall with different thicknesses and constructs. The theory research and date analysis of the tunnel kiln reform are carried out according to the steady-state heat transfer principle of multilayer kiln lining and the transferring parameter calculated by Excel.%以某双通道隧道窑技术改造工程为背景，从该隧道窑烧成带所截取最高温度段1m长度窑体为研究对象，分别从：①烧成带窑内气流运动情况；②火焰在窑内综合传热过程；③对比不同厚度及不同结构窑墙传热量计算值三个理论角度为依据。并根据稳态下多层炉衬传热原理，采用Excel进行辅助计算并得出相应的传热参数，从而完成对隧道窑改造工程的理论研究与数据分析。
