ABSTRACT:
Finely divided particulate material is discharged against the incandescent wall of a rotary furnace through a pipe extending into the open end of the furnace in a position where the material is out of the path of the flame projected into the furnace through the open end and out of the path of the outflowing gases. The material is retained against the interior wall of the furnace by centrifugal force and, as the material melts, it collects in a pool at the inner end of the furnace. The entrainment of fine particles and their subsequent removal with the exhaust furnace gases is thereby substantially reduced, if not entirely eliminated.
