Blast furnaces are currently rarely used in copper smelting, but modern lead smelting blast furnaces are much shorter than iron blast furnaces and are rectangular in shape. [76] Modern lead blast furnaces are constructed using water-cooled steel or copper jackets for the walls, and have no refractory linings in the side walls. [77]
Two blast furnaces have been preserved, including outer frames, furnaces and Cowper stoves. A protective paint coating minimizes the rusting effects on the blast furnaces. Blast furnace 6 is accessible to the public as part of guided tours. A colorful light installation illuminates the entire area at nighttime. [8] [9] Sulzbach-Rosenberg, Bavaria

The furnace was constructed circa 1847 by George W. Bryan, who named the furnace "fanny" for his wife. . Unlike earlier bloomery furnaces that produced wrought iron, the Valley Furnace was a blast furnace that produced pig iron using a bellows to induce a forced draft, using charcoal as a fuel. Ore was provided from surface mines that exploited ...

Blast furnace gas (BFG) [1] is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron. It has a very low heating value , about 3.5 MJ/m 3 (93 BTU /cu.ft), [ 2 ] because it consists of about 51 vol% nitrogen and 22 vol% carbon dioxide , which are not flammable.
Sloss Furnaces is a National Historic Landmark in Birmingham, Alabama in the United States.It operated as a pig iron-producing blast furnace from 1882 to 1971. After closing, it became one of the first industrial sites (and the only blast furnace) in the U.S. to be preserved and restored for public use.
For blast furnaces, direct reduction corresponds to the reduction of oxides by the carbon in the coke. However, in practice, direct reduction only plays a significant role in the final stage of iron reduction in a blast furnace, by helping to reduce wustite (FeO) to iron. In this case, the chemical reaction can be trivially described as follows ...
