摘要

The performance of an iron-bath reactor has been studied using a comprehensive numerical model that combines a computational fluid dynamics approach for the gas pahse and a heat and mass balance model for the bath. The model calculates: ·coal, ore, flux and oxygen consumption; ·post-combustion ratio (PCR); ·heat-transfer efficiency (HTE); ·off-gas temperature and composition; ·heat transfer and chemical reactions between gas and iron and slag droplets; and ·heat transfer between gas and bath, refractories and lance. The model was validated with data reported by the Nippon Steel Corporation for a 100t pilot plant, and the calculated and measured data are in good agreement.
