Evaluation of NOx-reduction measures for iron ore rotary

2020-3-2  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. The current paper is an assessment of NOx reduction measures that have been tested in pilot-scale and in full-scale by the Swedish iron ore

Rotary kilns TON Outotec

The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature. In a straight grate, the pellets at the top of the bed are “over cooked” and those at the bottom are “under cooked”. Higher quality means fewer fines, better reducibility and less variation in compression strength.

NOx formation in iron ore rotary kilns CORE

The work involves experiments in a pilot-scale kiln, as well as modeling work based on the same experiments. Data from a full-scale iron ore pelletization plant are also provided.From the experiments and the modeling work in this thesis, thermal NO is deemed to be of low importance in iron ore rotary kilns when solid fuels are combusted.
