CFD Modeling of the Industrial-Scale Bottom-Fired Direct Reduced Iron Reforming Process

S Parvathaneni, MW Andrade - Industrial & Engineering Chemistry …, 2024 - ACS Publications
In the iron and steel-making process, direct reduced iron (DRI) is the very first step that uses
CO and H2 to reduce iron ore and therefore contributes to fewer CO2 emissions than the …
