摘要
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-NOx system, it is necessary to control the sintering process to reduce NOx emissions. In this study, the influence of raw material and process condition parameters on NOx emissions was statistically analyzed with data from Baosteel's sintering production during 2013—2014. The results indicate that NOx 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.关键词
