Paul, F O

An entirely dry, solid waste disposal system is provided which incinerates waste in a manner to minimize pollution and to utilize the heat energy which is a by-product of the incineration. The waste material is shredded and then dried by mixing it with heated ambient air in an elongated dryer. A helix propels the waste through the dryer and into a combustion chamber together with the hot ambient air which was employed to dry the waste material. The hot gases resulting from incinerating the wastes are directed to a boiler wherein steam is generated. The steam thus produced is used to generate electricity and additionally may be utilized as a source of heat for heating or drying. The hot gases from the combustion chamber and the boiler are fed to the dryer for waste drying purposes. Exhaust gases from the dryer are fed to a scrubber to remove any remaining pollutants prior to being exhausted into the atmosphere.
