Abstract
An apparatus is provided for charging containerized fuel, particularly combustible hazardous waste homogenates, through a wall of a rotating kiln with minimal perturbation of mineral processing conditions. During kiln rotation fuel modules are loaded into the apparatus and charged into the kiln through a port in the kiln cylinder wall and onto the contained mineral bed. In a preferred embodiment the apparatus includes a device for actuating a port closure and a drop tube extending from the port into the kiln cylinder and positioned so that in-process mineral material does not contact the port closure during rotation of the kiln cylinder.
