The improved preheater comprises a charge box having a bottom, and a chamber having a bed. The chamber is in communication with the charge box at one end, and, an exit at the other. A pusher is provided for pushing the contents of the charge box into the chamber and thus pushing the contents of the chamber towards the exit. The chamber is of uniform expanding dimensions from its one end in communication with the charge box towards the exit. The bed of the chamber carries openings therethrough from a gas chamber therebelow into which heated waste gas is passed for circulation through the openings in the bed through the contents of the chamber.
