A furnace is a mechanical device designed, constructed, and used to generate heat (i.e. a heater). Depending on what kind is being used, a furnace serves to either heat the interior of a structure to prevent unwanted cold from ensuing, or to burn materials for the purpose of molding or cremating. Different kinds of furnaces include household furnaces, metallurgical furnaces, industrial furnaces, and incinerators.
