摘要

To better understand the conversion of alternative reducing agents (ARAs) in the blast furnace, a test reactor, designed to resemble blast furnace conditions, was built. A corresponding CFD model of the reactor was developed to enhance the understanding of the flow field, heat transfer, and reactions inside the reactor during ARA conversion. The temperatures inside the reactor, the calculated residence time of the particles, and the calculated burnout suggest a good agreement of the simulation and the experiment. The presented approach allows testing ARAs for the applicability in the blast furnace.
