| 1 | Effect of CO_2 and H_2O on gasification dissolution and deep reaction of coke显示文摘To more comprehensively analyze the effect of CO_2 and H_2O on the gasification dissolution reaction and deep reaction of coke, the reactions of coke with CO_2 and H_2O using high temperature gas–solid reaction apparatus over the range of 950–1250°C were studied, and the thermodynamic and kinetic analyses were also performed. The results show that the average reaction rate of coke with H_2O is about 1.3–6.5 times that with CO_2 in the experimental temperature range. At the same temperature, the endothermic effect of coke with H_2O is less than that with CO_2. As the pressure increases, the gasification dissolution reaction of coke shifts to the high-temperature zone. The use of hydrogen-rich fuels is conducive to decreasing the energy consumed inside the blast furnace, and a corresponding high-pressure operation will help to suppress the gasification dissolution reaction of coke and reduce its deterioration. The interfacial chemical reaction is the main rate-limiting step over the experimental temperature range. The activation energies of the reaction of coke with CO_2 and H_2O are 169.23 kJ ·mol-1 and 87.13 kJ·mol^(-1), respectively. Additionally, water vapor is more likely to diffuse into the coke interior at a lower temperature and thus aggravates the deterioration of coke in the middle upper part of blast furnace. | Zhi-yu Chang Ping Wang Jian-liang Zhang Ke-xin Jiao Yue-qiang Zhang Zheng-jian Liu | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，12： | 9 |
| 2 | 富氢高炉风口理论燃烧温度的数学模型开发显示文摘以传统的理论燃烧温度模型为基础,建立了高炉富氢燃料喷吹的新理论燃烧温度模型.基于某厂1号高炉的实际生产数据,验证了模型的准确性和可靠性.研究结果表明,富氢高炉理论燃烧温度新模型预测结果与高炉实测数据吻合良好.新模型以合理的理论燃烧温度范围为基准,分别获得了富氧率(f_(O))、煤比(M_(PCI))、天然气喷吹量(V_(NG))等参数与理论燃烧温度(t_(f))间的关系,同时还分析了3个操作参数间的合理匹配问题.新模型获得的参数匹配规律可以为不同企业的高炉在复合喷吹煤粉与天然气时实现稳定运行提供一定的参考依据. | 张晓辉 李海峰 徐万仁 邹宗树 | 2022 | 材料与冶金学报2022，21，1： | 1 |
