Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide. The blast furnace operates as a countercurrent exchange process whereas a bloomery does not.
Blast furnace 3, including the cast house, is one of the main components of the museum and features numerous information plates, exhibition pieces and documentary films on monitors. The blast furnace also serves as an observation platform. An elevator has been installed. A colorful light installation illuminates the blast furnace at night.
A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy ; processing metals with heat is even its own engineering specialty known as pyrometallurgy .
The Beckley Furnace Industrial Monument is a state-owned historic site preserving a 19th-century iron-making blast furnace on the north bank of the Blackberry River in the town of North Canaan, Connecticut. The site became a 12-acre (4.9 ha) state park in 1946; [2] it was added to the National Register of Historic Places in 1978. [3]
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 ...
The Ardis Furnace is an abandoned experimental blast furnace located at the northeast corner of Aragon and Antoine Streets (accessible from US-2) in Iron Mountain, Michigan, United States. The Ardis Furnace was designated a Michigan State Historic Site in 1971 and placed on the National Register of Historic Places in 1972.
