A furnace is a container or enclosed space in which a very hot fire is made, for example to melt metal, burn rubbish, or produce steam. arc furnace blast furnace electric furnace reverberatory furnace
is the part of the heating system in which the fuel is converted into heat by combustion It is made of cast iron, steel or stainless steel While cast iron furnaces consist of individual sections that can be assembled on site, steel and stainless steel furnaces are welded and delivered to their installation site completely assembled There are the following types of furnace
