Abstract
A rotary combustor for incinerating solid waste material, such as municipal trash, includes a combustion barrel supplied by air through windboxes underneath the barrel. Molten metal, such as aluminum, which is commonly present in the waste material, drops through perforations in the side wall of the combustion barrel and collects on a heated contact surface in each of the windboxes. The heated contact surface may have a funnel shape and be connected to a heated pipe for transferring the molten metal out of each windbox. Alternatively, the heated element may be attached to the interior surface of each windbox and separated therefrom by heat insulation. In this case, heated airlock doors at the lower end of the windboxes are used to discharge the molten metal from the windboxes.
