摘要

基于焦炉炼焦的流动、燃烧和传热过程，以质量守恒、能量守恒和动量守恒定律为基础，建立了焦炉燃烧室-炭化室耦合的三维非稳态数理模型，开展了数值模拟，将焦饼中心温度计算值与测量值进行了对比，进一步比较了3种不同水分蒸发模型的计算结果，分析了装炉煤水分含量、初始温度以及堆密度等工艺参数和操作参数对结焦时间的影响。研究结果表明，所建立的燃烧室-炭化室耦合模型能够较好地模拟焦饼的加热过程，并反映焦饼加热的高向均匀性，同时采用煤预热技术、煤调湿技术、煤料密实工艺可以很好地提高生产效率，为焦炉生产实际提供理论指导依据。

Abstract

To describe fluid flow

combustion and heat transfer in coke oven

a three-dimensional transient mathematical model with coupled coking and combustion chambers was developed and solved numerically. The calculated central temperature of the coke was compared with measured data. Three different evaporation models were compared. Effects of operational factors such as temperature

moisture content and density of charging coal were investigated. It is shown that the proposed model is suitable for describing thermal processes in the coke oven. It reveals whether the temperature distribution is uniform along the height of the chambers with coking evolution. Some measures may be used to improve the production efficiency

such as preheat

adjustment of moisture content

and densification for charging coal. This work is theoretically valuable for the operation of coke oven.
