to burn coke that will burn the raw material
to let air out
Its because air is forced into the furnace to increase temperature. Steve.
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.
Hot air under pressure
how does the blast furnace maintain the heat ?what is the function of CaCO3 ?how the slag protect the molten iron ?why does iron flow down to the bottom /how does the slag and molten iron get seperated ?what is use of waste gas /what is main impurity of iron in blast furnace ?
the blast furnace got its name , because its bottom which is called a furnace blows hot air to go up.
Hot air is blasted into the blast furnace to burn the coke (a cheap form of carbon) added to form carbon dioxide.
Blast furnace = Hochofen
Iron ore is used in a blast furnace as a raw material for producing iron. It is the primary source of iron, which is essential for the production of steel. The iron ore undergoes a series of chemical reactions in the blast furnace, resulting in the extraction of molten iron.
A blast furnace is used to extract iron from its ore.
Septum Valves are installed after the dust collector venturi scrubber , to decrease the pressure of Top gas from the blast furnace to supply it to other processes at low pressure.
Govăjdia Blast Furnace was created in 1810.
