摘要

Ironmaking blast furnace is a counter-,co-,cross-current moving bed reactor,where solid particles are charged at the furnace top forming a downward moving bed while gas are introduced at the lower part of furnace and travels upward through the solid bed of varying porosity,reducing solid ore to liquid iron at the cohesive zone.These three phases interact intensely.In this paper,a CFD-based mathematical model is developed for describing the complex in-furnace phenomena in a commercial blast furnace including flow,heat transfer and chemical reactions.The results demonstrate and characterize the key multiphase flow patterns of solid-gas-liquid at different regions inside the blast furnace.The model is then validated against the data collected from the commercial blast furnace.This model offers a cost-effective tool to understand and optimize blast furnace operation for cheaper and cleaner ironmaking.
