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 ...
Hashino iron mining and smelting site (橋野高炉跡, Hashino kōro ato) is the ruins of an iron smelting and primitive blast furnace built by the Tokugawa shogunate during the final years of the Edo period in the Hashino neighborhood of the city of Kamaishi, Iwate in the Tohoku region of northern Japan.
The hot blast pumps hot air into the blast furnace. The hot blast temperature ranges from 900 to 1,300 °C (1,650 to 2,370 °F) depending on the design and condition. Oil, tar , natural gas, powdered coal and oxygen can be injected to combine with the coke to release additional energy and increase the percentage of reducing gases present ...
the production of ferromanganese in the blast furnace requires a high manganese yield and therefore high basicities, up to i = 1.7 or 1.8 (bearing in mind that in this particular case, the index corresponds to = [] + [] + [] []!). Meltability is a secondary consideration in this case, as slag temperatures can reach 1,650°C (instead of 1,450°C ...
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.

The village of Leetonia developed the Cherry Valley Coke Ovens Park on the site. The area is heavily wooded area with hiking trails in and around the coke ovens and other sites of the former Cherry Valley Iron & Coal Co. The project was undertaken by the village of Leetonia to protect the site of a large part of the village's history. [4]
