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
In some larger furnace designs, molten metal and molten slag were tapped at the opposite narrow ends of the rectangular base. Water jacket furnaces typically had a higher number of smaller tuyeres than a conventional blast furnace. Typically, the feedstock was fed into a water jacket furnace through a sliding door arrangement in the side of the ...
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 ...

While still using 100 ovens, Leetonia Coal & Iron would process 250 tons of coal into coke per day. However, in 1873, the company was bought out and renamed "The Cherry Valley Iron and Coal Company", who expanded operations and eventually had over 200 coke ovens and 4 blast furnaces; processing much more coal than ever before.
Blast furnaces operate at temperatures above the melting point of iron and make molten pig iron, with molten slag as the waste product. In the 19th century, furnaces used either hot-blast technology—like modern blast furnaces, in which the blast air is preheated to a high temperature—or the older cold-blast technology.

Blast furnaces used in the ISP have a more intense operation than standard lead blast furnaces, with higher air blast rates per m 2 of hearth area and a higher coke consumption. [ 79 ] Zinc production with the ISP is more expensive than with electrolytic zinc plants, so several smelters operating this technology have closed in recent years. [ 80 ]
