The process of iron ore sintering is a non-equilibrium process that takes place within a very short time, and to clarify its process mechanisms, an analytical approach combining a phase diagram of a multi-component system and in-situ observation of high-tempera-ture reactions is effective. However, in-situ observation of high-tem-

Q. sintering of iron ore 1. INTRODUCTION - 40 to 50% iron ore becomes under size which may create pollution in the plant of the mine site. For the utilization of the variable ore, it is necessary to agglomerate the fines into the required size for charging in the blast furnace. Agglomeration is the size incensement process of the fines ore.

On Dioxin Formation in Iron Ore Sintering Environmental

Iron ore sintering is an important source of "dioxins", polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). This paper reports on attempts to identify materials, conditions, and mechanisms responsible for PCDD/F formation (i) by investigating salient properties of ores (viz., with respect to oxidation, condensation, and chlorination of model organics) and (ii) by mimicking the

Abstract. It is of great significance for cleaner production to substitute bio-energy for fossil fuels in iron ore sintering. However, with the replacement ratio increasing, the consistency of heat front and flame front is broken, and the thermal utilizing efficiency of fuel is reduced, which results in the decrease of yield and tumble index of sinter.

Influence of Coke Combustion on NOx Emission during Iron

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.
