Blast furnace

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. 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 to elemental iron mixed with carbon. The blast furnace operates as a countercurrent exchangeprocess whereas a bl

Blast Furnace ScienceAid

In the blast furnace, there are several chemical reactions taking place; that eventually result in the desired product (iron) being extracted. The coke (carbon) burns with oxygen to produce carbon dioxide. This reaction is exothermic. The CO 2 then reacts with more coke to give carbon monoxide.

Blast furnace metallurgy Britannica

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from
