Industrial furnaces are used for heating large areas. They can be purchased new and used. Several hits as to where to purchase are Used Furnaces, Grieve Corp and Furnace Brokers.

Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie
