CFD modeling of multiphase transport phenomena and reactions in an iron-making blast furnace
A CFD model based on multiphase transport theories is developed to describe the behaviors of the fluid flow,heat transfer,mass transport and thermo-chemical reactions between various phases,such as gas-solid ( ore/coke),gas-liquid ( hot metal/molten slag),gas-powders( PCI) and solid-liquid.The validity of the modeling is verified by comparing the predicted and measured technical indicators for a production BF.The internal state of BF,including pressure distribution,temperature and composition profiles of gas and solid phases,shape and position of cohesive zone,reduction degree of iron oxide,is successfully reproduced by using the model for a typical production BF.The model is also used to reveal the inadequate utilization of reducing gas and analyze the excessive potential distribution of the reducing gas.This may provide a clue for further improving blast furnace design and operation for maximum utilization of both physical and chemical energies of the fuel and reductant.
