Abstract
Combustion of solid fuel supplies heat in an iron ore sintering bed and the quality and productivity of the processes are highly dependent on the variation of operational parameters. To set the optimized operation modes through the application of various ideas, a numerical model can be employed prior to the conceptual designing of the actual plant. In this study, the effects of oxygen enrichment, increment of bed height, waste gas recirculation, as well as supplementary gaseous fuel combustion are investigated by employing a previously developed unsteady one-dimensional model of an iron ore sintering bed. Through the simulation, temperature distribution can be observed and used as the key data for the evaluation of the combustion efficiency. Flame front speed and sintering time, which represent propagation speed of the combustion zone, are also employed for quantification of the simulation. Through the parametric studies with numerical analysis, preliminary information about the detailed situation in the bed can be obtained.
