Blast furnace - WikipediaThe downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and Carbon2Chem-CCU as a Step Toward a Circular Economy14 Jan 2020 In a coking plant the coal is processed to coke for the blast furnace.
2 · 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
The blast furnace stoves (3), fueled normally by blast furnace medium Btu top gas (Utility Gas), burned by air, are used to heat an oxygen-rich hot air blast which is directed through the primary tuyeres (4) into the lower portion of the bosh to burn in front of them the char formed from the carbonaceous charge.

2021-3-15 · 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
2012-12-17 · Prior to the new boiler, ArcelorMittal burned about 22% of the blast furnace gas from Indiana Harbor operations before releasing it to the atmosphere through an exhaust stack, a process called flaring. The company used the remaining 78% of the gas to power boilers. The new boiler project further reduces the amount of waste gas that is flared.
