Abstract
An apparatus is provided for charging combustible solids through a port in the wall of a rotating kiln into a heated zone of the kiln. The apparatus includes a port closure comprising inner and outer portions which cooperate to define a passage for closure-cooling air flow when the closure is in a port-closed position. A transfer assembly is mounted on the kiln wall in alignment with the port. During kiln rotation combustible solids are loaded from a staging assembly onto the transfer assembly for alignment with the port and delivery into the kiln.
