Abstract
One of the recent areas of progress for better energy utilisation in iron ore sintering process is the distribution pattern of the fuel inside a macroparticle, which is formed with fine particles of iron ore, coke and limestone. Operational parameters for large scale industrial facilities, such as iron ore sintering plant, are commonly selected through a series of elaborate tests. The results of field experience in process improvement are introduced, and a theoretical modelling study is proposed to supplement the experimental based approach with fundamental physics based arguments, which enables predictive computation beyond the limited region of tests and adjustment. A single fuel particle model and a one-dimensional bed combustion model of solid particles are utilised, and the thermal process of combustion and heat transfer is found to be a dominant consideration in the discussions of productivity in the sintering process.
