Mathematical modeling of natural gas injection in iron ore sintering
Iron ore sinter, an iron-bearing material for BF iron-making, is utilised worldwide. A schematic of the NG injection technology is presented in Fig. 1.First, after being ignited by a burner, the coke/coal fines combust downwards and the sintering process between iron ores and flux occurs owing to the presence of a high-temperature zone.个人简历 胡杰，男，1992年生，湖南衡阳人。中国地质大学（武汉）自动化学院特任教授，中国地质大学（武汉）地大学者-青年拔尖人才（A类）计划入选者，中国自动化学会会员，湖北省科学技术厅科技专家库入库专家、学术桥评审专家库成员。2015年和2020年分别毕业于中国地质大学（武汉）自动化胡杰 中文主页 中国地质大学（武汉）教师个人主页系统 CUG

Numerical simulation of iron ore sintering process with coke
Oxygen enrichment is believed to improve productivity and reduce fuel consumption, while gas fuel injection is assumed to improve the product yield and quality in iron ore sintering process. It is important to understand the mutual effect of oxygen enrichment and gas fuel injection for combined usage of these two techniques. A mathematical model is Iwami Y, Iwase K, Hirosawa T, et al.

Recent progress in sustainable and energy-efficient technologies
The ultimate goal of the iron ore sintering process is to maximize the sinter productivity, strength, and reducibility (which are related to the energy consumption in the iron-making process), and to minimize the energy consumption and environmental impacts. Several methods may be considered to address these issues.Granulation and sintering are the two most important steps of the iron ore agglomeration process to produce sintered ore. Since granulation takes place at room temperature and is mainly characterized by physical and interfacial phenomena, while sintering is a thermal densification process involving extensive chemical reactions, the Sintering Characteristics of Iron Ore Blends Containing High

Volatile organic compounds (VOC) emissions control in iron ore
The iron ore sintering process commonly employs anthracite and coke as fuels, and the volatile matter is commonly<10%. Initially, we considered that the volatile matter of the fuel was closely related to the emissions of VOCs and investigated the effect of coal type on VOC emissions by sintering cup experiments [17].The present research focused on the charcoal combustion technique applied in iron ore sintering process. The comparisons of peak temperature, DTMT and MQI between coke combustion (Case 1) and charcoal combustion (Case 2) indicated that, the charcoal sintering performance was deteriorated due to the lacking heat release in Characteristics of charcoal combustion and its effects on iron-ore
