Coke Oven Gas Injection in a Blast Furnace – IspatGuru

Jul 19, 2014 · The injection of coke oven gas (COG) into the modern blast furnace is one of effective measures for steel industry to achieve low carbon ironmaking, energy saving and emission reduction. Coke is an essential input to the iron making process and is produced by heating coal in coke ovens. To make coke, coal is heated in the absence of oxygen to

Coke oven gas: Availability, properties, purification, and

Nov 01, 2013 · Coke is a very strong macro-porous carbonaceous material produced by the carbonization of a specific coal grade or of different coal blends at temperatures ⩾1400 K. Approximately 90% of coke produced from blends of coking coals is used to maintain the iron production process in a blast furnace …

Using Coke Oven Gas in a Blast Furnace Saves Over $6

Coke is an essential input to the steel-making process and is produced by heating coal in coke ovens. To make coke, coal is heated in the absence of oxygen to drive volatile matter from it. Coke oven gas, a low-BTU gas, is produced as a by-product of the process. Approximately 40% of the COG is used as a fuel in the coke oven.
