| 摘 要： | 采用实验方法研究了干熄炉内焦炭的冷却过程,得到了实验条件下不同位置焦炭的冷却曲线和气体温度、压力损失的变化趋势。根据多孔介质理论建立了非稳态传热和流体流动数学模型,对模型计算值和实验测量值进行了比较分析,结果表明模型具有较好的适用性,给出了二者存在偏差的原因。

| Abstract: | The coke cooling process in the coke dry quenching shaft furnace was investigated experimentally. The coke and gas temperatures and the pressure drop were measured. A mathematical model based on the non-Darician model for the transient process of fluid flow and heat transfer was established. The computational results were compared to the experimental data. It was found that the most numerical predictions were supported by the measured values. |
