Abstract [en]

In direct reduction of FeO with use of the process gas H2, diffusion takes place to remove the oxygen from FeO in form of H2O, where the reaction is a solid-gas reaction. The effect of pellet diameter and shape and inlet velocity of the H2 gas on the H2O concentration is studied by using COMSOL Multiphysics 4.2a. It was found that the H2O concentration is deeply dependent on pellet size and inlet velocity. The effect of the velocity is inversely proportional to the H2O concentration, which means the higher the velocity the less is the observed concentration. The simulation also shows that the concentration increases with increasing pellet size because of the larger surface area. It was also found that the orientation of the pellet has major effect on the H2O concentration and therefore on the reduction of the pellet.
