摘　　要：利用CFD（计算流体力学）软件，以首钢焦化厂实际生产数据为依据，建立焦炉炭化室传热数学模型，分别对不同炉墙厚度、不同标准火道温度的炭化室进行模拟研究，探究炉墙减薄对结焦时间、加热温度以及传热量的影响。研究结果表明，相同标准火道温度下，炉墙减薄10mm，结焦时间缩短0．9h；相同结焦时间下，炉墙减薄10mm，标准火道温度降低25—27℃，从而降低能耗；炉墙减薄不会降低墙体的热稳定性。On the utilization of CFD （computational fluid dynamics） software and in terms of the industry data of the Beijing coking plant, the mathematical model of heat transfer in the coke oven chamber was established. And simulation goes on the different heating wall width and standard flue temperature, respectively, in order to investigate the effect of the thinner heating wall to coking time, heating temperature and heat flux. The results suggest that when 10 mm shortened of the heating wall the coking time reduces by 0.9 hour on the condition of the same standard flue temperature, while the standard flue temperature reduces by 25 - 27 ℃ of the same coking time. It is unable to thin the thermal stability of the thinner heating wall.
