coal production of blast furnace equipment

Blast Furnace - an overview ScienceDirect Topics

Coke oven gas is the by-product of the pyrolysis of coal, which is the basic process for coke production for the blast furnace process. It typically contains about 5% carbon monoxide (CO), about 55% hydrogen (H 2 ), about 25% methane (CH 4 ) and about 3% higher hydrocarbons as combustible components.

Blast Furnace System Industrial Efficiency Technology ...

In a blast furnace (BF) the iron oxides are reduced and the resulting iron is melted. Approximately 70% of the global steel production involves the use of BFs. Sizes of BFs installed cover a very wide spectrum, ranging from less than 100 m3 to more than 5000 m3. Larger BFs have less heat losses and enable installation of heat recovery equipment more cost effectively (IEA, 2007.p. 116).
