DESC:PLS SEE THE ATTACHMENT ,CLAIMS:I/We claim-
1. A method(300) for performing a gas based direct reduction of iron using nut coke, the method (300) comprising:
feeding (302), a predetermined quantity of nut coke to a feeding system of a DRI plant via a transfer system (114), wherein the predetermined quantity of nut coke is received in a nut coke surge bin (104);
feeding (304), a predetermined quantity of iron ore pellet to the feeding system of a DRI plant via a transfer system (114), wherein the predetermined quantity of iron ore pellet is received in a pellet surge bin (108);
mixing(306), the predetermined quantity of nut coke with iron ore pellets at a Reduction Furnace (RF) (110), to produce a first mixture wherein the nut coke in the first mixture reacts with CO2 and H2O in the reduction furnace (110) at a predetermined temperature for a generation of one or more reducing gases, further wherein the reducing gases reduce Iron Oxide (Fe2O3) to metallic iron (Fe) forming iron carbides (Fe3C).
2. The method(300) as claimed in claim 1, further comprising:
adjusting a feed rate of the predetermined quantity of nut coke into the reduction furnace (110) relative to a production capacity for the reduction of iron oxide (Fe2O3).
3. The method(300) as claimed in claim 1, wherein the reduced Iron (DRI) comprises of higher metallic iron content and enhanced carbon percentage of 0.8% to 1.1%..
4. The method (300) as claimed in claim 1, wherein the predetermined temperature is at a range of 750- 7800C.
5. The method(300) as claimed in the claim 1, wherein the one or more reducing gases comprises carbon monoxide (CO) and hydrogen (H2).
6. The method(300) as claimed in the claim 1,wherein the metallic iron content of the direct reduced iron ranges from 80.5%- 81.5%.
7. The method(300) as claimed in the claim 1, wherein the incorporation of nut coke with iron ore pellets reduces external gas consumption per ton of the direct reduced iron by a range of 18 to 20 Nm3/hr .
