NOx Reduction in the Iron Ore Sintering Process with Flue

Abstract. Flue gas recirculation (FGR) has been implemented for exhaust gas emissions reduction in iron ore sintering. However, the mechanism of NO x reduction through FGR is still unclear. In this paper, the laboratory potgrate sintering test showed a 30% reduction in gas flow and 15.51% reduction in NO x emissions achieved with a 30% FGR ratio, and the sinter indexes almost matched those of
