摘要

The aim of this study was to relate the combustion rate of solid fuel for iron ore sintering process to its physical and chemical properties. In this study, we used 23 carbon materials including cokes, anthracites, charcoals, and so on. The physical and chemical properties of the carbon materials such as proximate and ultimate analysis, specific surface area, particle density, and porosity were evaluated. The combustion rates of the carbon materials were measured using thermobalance and fixed-bed combustion reactor. In the low temperature region, the combustion rates depended on the types of the carbon materials. This would be because the carbon structure and the volatile matter content affected the combustion rates significantly. In the high temperature region, on the other hand, the combustion rates were almost the same regardless of the types of the carbon materials.
