Fossil-Fuel Furnaces
The reverberatory furnace used to melt aluminum scrap has numerous designs and
sizes, and new designs appear on a regular basis. However, new furnaces are expen-
sive, and so many older designs are still widely used. The goal of furnace design is
consistent, however: to generate the highest melting capacity per unit volume, while
maximizing thermal efciency to reduce fuel costs. Other considerations include the
ability of the furnace to handle nely divided scrap without excessive melt loss, the
ability to process coated scrap if prior decoating is unavailable, minimizing mainte-
nance costs, and ease of charging and tapping. ...
