Hydrogen, as a carbon-free fuel and reducing agent, has the potential to mitigate carbon
dioxide emission in BF ironmaking and the shaft injection is one of the promising and …

This paper presents a numerical study of the influence of burden profile on gas-solid
distribution in a COREX shaft furnace through CFD-DEM model. The model takes into …

Central coke charging is an effective way to prevent coke collapse, which helps to improve
the ore-to-coke ratio and further the gas utilization and CO 2 emissions. Therefore, a three …

Coke collapse is very important in blast furnaces as it determines the ore-to-coke ratio and
further affects the gas utilization and CO 2 emissions. Therefore, a three-dimensional model …

This work investigates the effects of burden profile on particle segregation, void distribution
and gas flow in an ironmaking COREX shaft furnace using DEM-CFD model. The simulation …

A three-dimensional steady state mathematical model, considering the chemical reactions
and the transfers of momentum, heat and mass between the gas and solid phases, is …

In order to develop the central gas flow in COREX shaft furnace, a new installment of center
gas supply device (CGD) is designed. In this work, a coupled DEM–CFD model was …

In this paper, the fluid dynamics software Fluent is used to simulate the gas–liquid two-
phase flow characteristics of a bottom-blown furnace under four different scale-up criteria …

The paper shows the use of novel modelling techniques adapted from ironmaking in the
pyrometallurgical process of zinc production. Firstly, regarding the purpose to determine the …

The residence properties of gas-solid phases are important to the design and process
optimization of a COREX shaft furnace. In this study, we investigated the gas-solid residence …
