Dear Readers, In this presentation, I have tried to explain main raw material sources of iron making process. Also, with my experience, I have tried to give a concept about the plant engineering related to raw material. I hope that, this presentation will be helpful for young engineers. With this presentation they will get a broad idea about the raw material, based on which they can study more on the subject. Regards, Nirjhar.

33. Coal & Coke Section: Coke Oven Plant Coke inside oven ready for push out from oven

34. Coal & Coke Section: Coke Oven Plant Hot Coke pushed out from oven

36. Coal & Coke Section: Coke Oven Plant Hot coke being pushed from an oven into a quench car. Quenching Car Locomotive engine of quenching car Coke collected on quenching car Coke Oven

37. Coal & Coke Section: Coke Oven Plant The Quenching car travels and placed below the quench tower. The coke is treated to high-pressure water jets to cool the coke while still in the quench car. The coke is discharged from car and crushed into pieces and stacked. Quench Tower Quenching Car with coke
