Auger combustor with fluidized bed

An incinerator for burning combustible materials, comprising:

• an elongated horizontally disposed stationary combustion chamber means, said chamber means having a first end with an inlet for receiving combustible materials into its interior and a second end with an outlet for discharging exhaust gases and combustion residue therefrom, the horizontal position of said elongated stationary combustion chamber means defining an upper and a lower side thereof, with a plurality of openings in the lower side thereof;
• and
• a screw conveyor means extending through said chamber means' interior from proximate said first end to proximate said second end for moving materials therethrough, said screw conveyor means being a rotatable auger including:
• an axial member having two ends;
• a plurality of support members rigidly connected to said axial member;
• and
• a plurality of adjacent spiral flights disposed about said axial member in such manner that they form a continuous helix around said axial member, each of said flights having a leading edge and a trailing edge, the trailing edge of each of said flights slidably overlapping the leading edge of the adjacent one of said flights, each of said spiral flights being rigidly connected to a single support member and slidably connected to additional support members, said support members connecting and supporting said spiral flights in spaced concentric helical relationship to said axial member and defining an open annular space around said axial member.
