In Rotary Hearth Furnace, iron ore coal composite agglomerate moves over the rotating hearth through different temperature regimes and counter current to the hot gas flow to produce sponge iron. A mathematical model for RHF has been developed that incorporates two sub-models to predict the phase evolution in solid bed over the hearth as well as to simulate the flow, temperature, and concentration field distribution in the freeboard over the hearth. The first sub-model is used to simulate gas flow and combustion process in the chamber of RHF by using FLUENT. The second sub-model is established to describe the direct reduction process of composite agglomerate over the hearth of RHF. The composite agglomerate stacked in multi-layers over the hearth is considered as a single solid mass with an energy sink and source for CO/CO2 for the sub model 1. The results from the model will be discussed in the presentation.
