Coal Gasification Plant and use of by-products, Angul . Direct-reduced iron (DRI), also called sponge iron is produced from direct reduction of iron (in the form of lump, pellets or fines) by a reducing gases produced from natural gas or coal. This reduction takes place in the temperature range 800- 1050 degrees C when reducing gases; mainly Hydrogen and Carbon-monoxide; react with the iron ...

When pre-reduced fine ore is to be used in an existing blast fur-nace, the tuyere of the furnace is enabled to inject the pre-reduced fine ore into the furnace. When the pre-reduced ore is in the form of a lump, it is fed into the furnace from the top. In either case, the pre-reduced iron ore undergoes final reduction using a coal-based en-

As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI). The reduced product having high degree of metallization shows a 'honeycomb structure', due to which it is often called sponge iron. Coal based DRI plants are flexible with respect to plant location ...

There are large industrial plants operating today that use natural gas to produce direct-reduced iron followed by an electric arc furnace to turn that iron into steel. In those plants, natural gas is cracked apart to make hydrogen, which makes up the bulk of the gas used to reduce iron and produce heat. Already these plants have about half the carbon emissions of coal-based steel plants.

More attention is paid to ironmaking as the most energy consuming segment of the process chain. For example, blast furnace ironmaking including sintering and coking plants consumes about 65-75% of the entire energy at an integrated steelworks (ca. 11–12 GJ/t hot metal) (Babich, 2009).Both direct and indirect coal use, e.g. in the form of coke, is presented.

The natural-gas-based DRI processes, however, limit plant locations to places where natural gas is available. On the other hand, coal-based DRI plants are flexible as to plant location, because coal is widely distributed in large deposits and is easy to transport. This has significantly increased the production of coal-based DRI.
