Abstract: A method and apparatus for the consumption of relatively mass amounts of refuse in which a plurality of refuse burning grates are spaced one above the other. The refuse is supplied to and deposited selectively on selected ones or all of the grates while the grates are rotating so as to substantially evenly distribute the refuse thereon. The refuse is ignited to cause the same to burn and be consumed thereby becoming reduced in size such that the smaller sized refuse is enabled to fall through the grates producing a continual cleaning of the grates.

Abstract: An apparatus and method for utilizing the heat of waste gases by exhausting the same at the head of a flue from a source into a heat extractor where the hot gases are caused to move and turbulate about heat exchanger walls to release their heat to such walls before being exhausted downward to the atmosphere so that fluids moved through the heat exchanger may be heated to perform useful work.

Abstract: A method and incinerator apparatus for cleaning and utilizing the waste gases thereof to perform work after the residue and particles that pollute and contaminate the same are removed therefrom. After the waste gases are subjected to and scrubbed at high temperatures to burn and consume the particles and residue, remaining particles and residue are further separated in a heat accumulator from which the higher temperature waste gases are used as an aid in the scrubbing and cleaning the lower temperature waste gases and from which the heat of the waste gases is extracted for the performance of work.
