摘　　要：建立了干熄炉内焦炭层床循环气体的传热模型,并耦合燃烧反应计算,分析了干熄炉冷却室内的温度变化,计算结果与实测数据基本一致。本文还进一步分析了化学反应活化能、风料比和燃烧反应对干熄炉内传热的影响,以期为干熄炉的优化设计提供一定参考。To build a heat transfer model for the gas in the coke packed bed in CDQ, coupling combustion reaction calculation, the author analysed the change of tempeture distribution in furnace of CDQ. it has been proved that the results coincide with the experimental data. The author also analysed the the influence of chemical activation energy, ratio of the gas/coke, and combustion reaction for the heat transfer in CDQ chamber, it will provide good reference for the optimum design of CDQ.
