Abstract: After effectively controlling the desulfurization of sintering flue gas, steel companies are now putting denitration on their agendas. In the absence of an economically viable and efficient end-of-pipe de-NO_x system, it is necessary to control the sintering process to reduce NO_x emissions. In this study, the influence of raw material and process condition parameters on NO_x emissions was statistically analyzed with data from Baosteel's sintering production during 2013-2014. The results indicate that NO_x emission levels associated with the sintering process can be lowered by decreasing the percentage of hematite, raising sintering fines and the return fines ratios, and enhancing the cold-air permeability, calcium ratio, and sintering bed depth.
