Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a travelinggrate machine is used, and the burning of fine coke (known as coke breeze ) within the ore generates the necessary heat....
Biomass for iron ore sintering_
Most of the heat required in the production of molten iron is typically provided by the combustion of a solid fuel coke. For example, in an integrated steel works the heat required for making sinter is usually provided by combustion of coke breeze which is generally derived from the screening of coke for the blast furnace. In some works ......
