Abstract

A rotary batch preheating kiln feeding batch materials to a batch liquefying vessel is separated from the liquefying vessel by a transition section including duct means to direct exhaust gas from the liquefying vessel to the interior of the rotary kiln at a location spaced from the discharge location of the kiln. The transition section also shields the rotary kiln from radiant heat from the liquefaction vessel.
