The COB will be similar to the existing ones, 7 metre tall and 67 Ovens each and a By-product recovery – Top charge type battery.

The COB-5 will generate 14 MW of power through waste heat recovery project also.

RINL is presently having four Coke Oven Batteries producing 2.48 million Tons of BF grade Coke. The Coke requirement for the Blast Furnaces (net & dry) for 6.5 mtpa capacity has been estimated at 2.88 mtpa with 15 per cent ash content.
