Abstract

An improved, essentially pollution-free incinerator for waste materials is provided which includes vertically stacked, separately fired primary and secondary combustion chambers and central, cooperating, apertured partition and baffle structure serving to assure complete burning of the waste materials and removal of particulate solids prior to discharge thereof to the atmosphere. In preferred forms, the central, chamber-defining partition includes a plurality of circumferentially spaced, peripheral apertures, while the baffle structure is in the form of an annular, peripheral shoulder formed on the inner wall surface of the secondary chamber above the partition apertures. The primary chamber also includes a waste material inlet and a burner system for igniting the waste materials, while the secondary chamber has tangentially disposed air and fuel inlets for creating a whirling flow pattern to assure essentially complete high temperature burning of the waste materials.

Dependent claims

An incinerator, comprising:

structure defining a primary combustion chamber for receiving waste materials to be burned, and an adjacent secondary combustion chamber positioned above said primary chamber;
generally horizontally disposed partition means situated between said primary and secondary combustion chambers and configured to present a plurality of relatively small combustion gas-conveying apertures therethrough which communicate said primary and secondary chambers, have upright axes, are located in spaced relationship about the periphery of the partition means, and cooperatively present a total open area in communication with the primary chamber which is substantially less than the total surface area of the face of said partition means adjacent the primary chamber;
and
peripheral baffle structure located within said secondary chamber adjacent to and directly above said apertures for removal of at least a portion of any solids entrained in the gases passing through said apertures by slowing and lateral deflection of said gases as the latter pass the baffle means, and for repassage of a part of said removed solids back through said certain apertures.
