Abstract: In iron ore sintering, the granulation process is the first and an important step. As the fine particles adhere to the coarse coke particles, the NOx emission generated from coke combustion may be expected to be influenced by that adhering layer. In this study, the granule size distributions and adhering ratios were evaluated by a granulation model. granulation experiments were also carried out to obtain the granule size distribution and adhering ratio. The influence of the adhering layer on NOx emissions from the combustion of S type granules was studied by tube furnace experiments. Conclusions include: (1) The adhering ratio predicted from the granulation model can be used as a qualitative index for the evaluation of NOx emission from coke combustion. (2) The influence of the adhering layer on NOx emissions was enhanced with increasing adhering layer thickness of S type granules, and the NOx reduction was enhanced at higher temperatures (around 1373 K), but weakened at lower temperatures (around 1173 K).
