Coke combustion inside the iron ore sintering process is a major source of NOx in the steel industry.All the associated combustion reactions can be categorized as packed-bed combustion.In this study, the time-course profile of the conversion rate of fuel-N in coke to NOx was determined during packed-bed combustion. The conversion rate was calculated at each reaction time by analyzing the results of in-situ gas measurement inside the iron ore sintering reactor during the combustion.Both the emission of NO and the conversion rate were found to be higher in the lower-temperature region in the combustion layer, corresponding to the beginning of coke combustion.
