ABSTRACT:
A combustion barrel used in a rotary combustor is constructed of cooling pipes joined by perforated webs to form a generally cylindrical side wall. Water-cooled baffle pipes are attached to the interior of the generally cylindrical side wall at widely spaced intervals. The baffle pipes and cooling pipes are coupled at an exit end of the combustion barrel to a ring header which in turn is coupled to heat exchanging equipment. The ring header supplies low-energy coolant from the heat exchanger to the cooling and baffle pipes and discharges high-energy coolant from the cooling and baffle pipes to the heat exchanging equipment. At an input end of the combustion barrel, the cooling and baffle pipes are coupled to U-tubes or a return header for returning the coolant to the ring header. Solid material is supplied at the input end of the combustion barrel for incineration. The combustion barrel is slowly rotated as the solid material is transported to the exit end of the barrel. The water-cooled baffle pipes agitate the solid material enabling more complete incineration of the solid material.
