Mar 28, 2017· It uses non-coking coal in a powder or granular form to smelt iron ore fines into liquid iron (hot metal) and hence, there is no necessity of a coke ovens plant and a sintering plant. The ore fines are pre-reduced in a fluidized bed furnace and are charged in the smelting reduction furnace along with non-coking coal and fluxes.
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
However, the combustion reactivity improvement of ilmenite decreased with a higher concentration of H2S due to the formation of sulfur deposits (e.g., Fe1-xS) on the reduced iron particles.

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
during combustion because they are pure, uniform substances with well-characterized phase transitions and thermodynamic properties. This is in marked contrast to the complex structures and heterogeneous chemistry associated with the combustion of carbonaceous materials such as coal and grain dusts.
