      Ferro-coke | Challenge Zero

      Ferro-coke is an innovative material for a blast furnace which improve reduction reaction of iron ore inside the blast furnace and resulting in significant reduction of CO 2 emission. Ferro-coke is a hybrid agglomeration of coke and metallic iron which are produced from coal and iron ore by crushing, mixing, formed and heated in a continuous carbonizing furnace.

      Influence of Coke Combustion on NOx Emission during Iron ...

      Increasing coke size may result in the decrease or increase of NOx emission. Placing coke particles on the outside of granules can lower NOx emission in the middle and bottom layers, by 4–15%. NOx emission in the iron ore sinter process is determined by the conversion of coke-N to NOx and nitrogen source in sinter mix.
