The blast furnace is used in extracting iron and is a tall structure, usually about 30 meters high, which is made of iron or steel and lined with firebrick. It is narrow at the top, then increasing in diameter until it reaches the bottom, where it again narrows.
Aug 03, 2011· At the high temperature at the bottom of the furnace, carbon dioxide reacts with carbon to produce carbon monoxide. It is the carbon monoxide which is the main reducing agent in the furnace. In the hotter parts of the furnace, the carbon itself also acts as a reducing agent.
Describe the essential reactions in the extraction of iron in the blast furnace. An ore is a rock from which metals can be extracted. The main ore of iron is hematite, which contains large amounts of iron(III)oxide. It is reduced by carbon to for iron, but this takes place in a huge blast furnace.

Furnace Fume Extraction Systems. Induction arc furnaces are offered to control their resulting pollution control by exctraction thro' swilling/ water cooled hoods or third hole. The extracted hot fumes gases (often flame laden) are taken away to TECHFLOW air pollution treatment control systems.
Blast furnace. The iron oxides in the ore are chemically reduced to molten iron by carbon and carbon monoxide from the coke. The slag formed consists of the limestone flux, ash from the coke, and substances formed by the reaction of impurities in the ore with the flux; it floats in a molten state on the top of the molten iron.
Stages in the extraction of iron in a blast furnace are described below after iron ore, coke and limestone have been added at the top, but not in the correct order.
