Numerical Simulation of Thermal Process in Rotary Hearth Furnace for Pellet Direct Reduction
A mathematical model of complex thermal processes with combustion, radiation and flow in rotary hearth furnace (RHF) for pellet direct reduction is established with CFD commercial software Fluent. Temperature distribution, pressure field and flow field in RHF are simultaneously analyzed by numerical method. It has been found that the temperature distribution in the furnace can meet the need of thermal institution for pellet direct reduction, and great pressure field and flow field can be formed on the basis of reasonable arrangement of burner, nozzle and partition. The simulation results would be helpful for engineering design and parameter optimization of RHF.
