Abstract

It is thought that numerical simulation model for estimation of temperature distribution in the iron ore sintering process is useful tool for stable operation of this process. The purpose of this study is to develop new numerical simulation model based on a combination of Hottel’s equation and coke combustion rate equation in quasi-particle derived from previous study. The following results were obtained. More practical temperature distribution could be calculated using coke combustion rate from previous work than in case of using only Hottel’s equation. Decrease of temperature distribution in the sintering layer was found with consideration of the liquid phase formation effect on coke combustion rate. This effect will increase with increasing of fine coke amount in the process.
