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).
