PAT and coal based DRI: Sponge Iron industry comes under Iron Steel sector with sectoral energy reduction target of mMTOE(million metric tones of oil equivalent). For a coal based DRI plant with waste heat recovery boiler, power plant and having arrangement for selling surplus electricity, the gate in energy would be coal
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...
Sponge iron or directreduced iron is a transitional material used in the production of steel. Either coal or natural gas is used in sponge iron production. In India, noncoking coal is easily available. Thus, the sector depends mostly on coalbased sponge iron and nearly 80% of the total coalbased sponge iron plants are located in
