In a global carbon cycle, the net greenhouse gas (e.g., CO2) emissions can be significantly reduced if fossil fuels could be substituted with renewable and cleaner biomass-derived fuels. In the traditional iron ore sintering process, the complete replacement of coke, a coal-derived fuel, with charcoal is not possible because the two fuels have very different properties and combustion behaviors, resulting in an unacceptable deterioration in sintering performance. Consequently, only low substitution ratios can be tolerated. However, research has indicated that this ratio can be increased through altering the combustion behavior of charcoal. Most fuel particles in a sintering bed have an encapsulated layer of fine ore and flux particles. Through intentionally altering the properties of this adhering layer, combustion behavior can be altered, leading to improved sintering performance. This work uses a newly developed combustion model and a 2D sintering model to appropriately describe the combustion behavior i...
