<p>A device for thermally treating scrap employs a charging facility for conveying scrap to a furnace chamber. The charging facility is fitted with a waste gas flue and a loading port and has a pre-loading space in which the scrap is pre-heated. The device is easily operated and can be run with relatively little loss of energy by having the pre-loading space of the charging facility releasably connected to the furnace chamber and/or waste gas flue such that the pre-loading space is fed with waste heat from the furnace chamber. Preferably the pre-loading space is part of a waste gas or waste heat circuit. The pre-loading space is also provided with an extendable unit which can be pushed into the mouth or loading port of the furnace for feeding the scrap to the furnace.</p> |
