Evaluation of NOx-reduction measures for iron ore . The Grate-Kiln process is employed for sintering and oxidation of iron ore pellets. In this process, a fuel (typically coal) is combusted with a large amount of excess air in a rotary kiln and the high air-to-fuel ratio leads to significant NOx formation.
