ABSTRACT
In this study, hydrogen reduction of in-flight fine particles of magnetite ore concentrate at constant heat flux condition has been investigated, experimentally and numerically. A 3D turbulent mathematical model was developed to simulate the dynamic motion of these particles and also progress of the reaction. An experimental set-up was made up to evaluate the simulation. The fabricated set-up contains a vertical furnace, a ceramic tube and a handmade powder feeder. There was an excellent agreement between the prediction results and the experimental data. Our simulation and also the experimental data showed a large fraction of the inlet particles traps in the reactor. This is an important issue, should be solved in an industrial scale of the process.
