NOx Formation in Rotary Kilns for Iron Ore Pelletization


Sep 25, 2017· The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this is produced by combusting a pulverized fuel in a rotary kiln, forming a suspension flame. Due to the need to oxidize the pellets ...
