what are blast and crucible furnaces
to heat the iron so that it separates from other elements in the ore
First: Roast the Galena in a blast furnace for 30 minuets. Second: Add Carbon to the blast furnace to remove impurities. Third: Tag off your lead from the bottom of the blast furnace.
Coke contains more carbon than coal and hence coke produces more heat
Co2 (g)+C(s)--->2CO(g)

the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.
In a furnace large amount of the heat supplied is wasted in the form of exhaust or flue gases.. that s called as heat loss in a furnace..
Blast furnace = Hochofen
A blast furnace is used to extract iron from its ore.
Its because air is forced into the furnace to increase temperature. Steve.
