摘　　要：根据干熄炉内焦炭换热的特点,用干熄炉模型对焦炭粒度和冷却气体流量等参数进行了试验。结果表明,平均体积换热系数随焦炭粒度变小而急剧增加。According to the feature of coke heat exchanging in CDQ chamber, the test on the parameters such as coke size and cooling gas flow was made with the CDQ model. The test results showed that the average volume heat exchanging coefficient was increased with the reduction of coke size.

关 键 词：干熄炉 平均换热系数 模型 焦炭粒度 冷却气体
