Apparatus for recovering energy and useful products from plantain wastes

Details

Inventors: Quame, Babington A.;
Assignee:
Primary Examiner: Garris; Bradley
Assistant Examiner:
Attorney, Agent or Firm: Steinberg & Raskin

Energy and useful products are recovered from plantain wastes in a self-contained waste treatment plant wherein the raw material waste is charged into a boiler where the same is combusted to produce flue gases containing several organic compounds and dry ash containing residue mineral salts. The flue gas heats water in a water reservoir to generate steam which drives a turbine generator to produce electricity, the flue gas then being collected and at least partially condensed to form a pyroligneous acid solution from which alcohols and the like can be recovered. The dry ash containing residue mineral salt is mixed with other minerals or reagents with the resulting mass being supplied into a continuously stirred fusion furnace situated within the boiler to which heat is supplied by the flue gas to produce commercially useful products, such as zeolites, dolomite or other related products.

DETAILED DESCRIPTION What is claimed is: 1.
Apparatus for recovering energy and useful products from waste raw material comprising: a housing having a burner provided at a lower firing region thereof and a gas discharge opening at an upper region thereof; a furnace disparate from but situated within said housing in the path of flue gas generated at said firing region, said furnace including an inlet region adapted to receive a mass of mixed material, an outlet region, and means for stirring the mass of mixed material as the same is transported from said inlet region to said outlet region thereof, said flue gas transferring heat to the mass of mixed material received within said furnace to form useful compounds; means for transferring solid residue from said firing region of said housing to said inlet region of said furnace as a component of said mixed material; means for generating steam situated within said housing, said steam generating means being located in the path of flue gas generated at said firing region, said steam generating means including a water reservoir, and said flue gas transferring heat to the water contained within said reservoir to generate steam useful for producing energy; and means for condensing the flue gas generated at said firing region and for recovering any remaining flue gas.
2.
The combination of claim 1 further including means situated within said firing region of said housing for stirring a burning mass of waste raw material to facilitate combustion thereof.
3.
The combination of claim 1 wherein an apertured plate is situated within said housing beneath said firing region onto which a solid residue of combustion is adapted to fall.
4.
The combination of claim 1 further including means situated beneath said firing region for conveying a solid residue of combustion to a discharge point.
5.
The combination of claim 1 wherein said furnace comprises a plurality of chambers situated one above the other in communication with each other, said chambers being in the path of flue gas generated at said firing region
