| 摘 要： | 通过对本钢5^#高炉喷枪喷煤模拟，建立二维气-粉流动模型，对煤粉从煤枪喷射出流后的流动状态进行表征。研究了喷煤过程的流体力学行为，得到了煤粉喷吹时高妒炉内射流区域流场、温度场、浓度场，对不同煤粉浓度下的数据进行了对比分析，结果表明：随煤粉初始浓度增加，煤粉射流中心温度降低，二氧化碳生成量降低，燃烧产物中未燃煤粉量增加。通过计算机模拟，可以找出设备存在的不足和各种操作参数对高炉运行产生的影响，为喷枪的改造提供理论依据。

| Abstract: | A two-dimensional mathematic model was developed to study behaviors of the coal after injection into the blast furnace.The velocity distribution,mass fraction distribution and temperature distribution in injecting zone were obtained from the numerical model of No.5 Blast Furnace in Benxi Steel in this paper.From analyzing the parameters in different situation,following results were obtained: The temperature in the middle zone of the injection flow and the outcome of the CO2 become lower with increasing of t... |
