This paper explores NOx emission during iron ore sintering on a pilot-scale pot. A novel technique of using a three-layered bed structure was adopted to study the role of coke level, properties and combustion behavior on NOx emission. In addition, the lime content of the mix was also altered to understand the effect of the melt formation process. Thirteen sinter pot tests were employed to ...
The mini-sintering method includes ore blending, briquetting, sintering, and cooling. Specifically, fine-grained iron ores within a size range of 5 mm were mixed with fluxes limestone, quicklime, and dolomite, and then ground to a size under 0.074 mm and compressed into a standard pyrometric cone 20 mm in height and a side length of 5 mm.
