Abstract
Apparatus for heating elements broken up in small pieces wherein the pieces are loaded into baskets with solid vertical walls and perforated or porous bases, and are pushed in a continuous line into a tunnel to there introduce a hot gas which passes vertically through each basket and its contents. A principal application is the preheating of products feeding a smelting or resmelting furnace, and in this case the hot gases used are fumes from the furnace.
