ABSTRACT:
A solid waste disposal unit having a lower, pyrolyzing chamber and an upper, oxidizing chamber separated by a movable plate. Waste is deposited in the lower chamber. The chambers are rotated to move the plate to a first position which seals the lower chamber from the entrance of air. While the chambers continue to rotate, a pair of heaters separately heats the chambers. The waste in the lower chamber is pyrolyzed in the absence of air and gives off a combustible vapor that in turn is oxidized in the upper chamber. A plurality of venturi jets, mounted in the movable plate, mix the vapor with air as the vapor passes into the upper chamber. Additional air is introduced into the upper chamber through a rotating regenerative heat exchanger recovering heat from the exhaust gases. After the waste is thoroughly pyrolyzed into a char, the rotation of the unit is reversed causing the movable plate to rotate into a new position wherein air is permitted to enter the lower chamber to cause oxidation of the char. This oxidation process continues until the char is entirely consumed and reduced to a sterile ash. Any gaseous products produced will continue to be oxidized in both chambers.
