Patent ID: 7814845

Claim:
An incinerator and gasifier for gasifying biomass waste in alternately loaded batches thereof, said gasifier and incinerator comprising: first and second primary chambers adapted to receive biomass waste therein for incineration and gasification thereof; first and second fume transfer vents disposed near the top of said first and second primary chambers, respectively, and in fluid communication therewith so as to permit the escape of fumes from said first and second primary chambers, respectively; first and second afterburner chambers in fluid communication with said first and second primary chambers, respectively; first and second secondary burner members in said incinerator and gasifier so as to produce an initial flame within a first vertically disposed portion of each of said first and second afterburner chambers, respectively, wherein each of said first and second secondary burner members has a respective fuel inlet and an air inlet to permit the supply of fuel and oxygen to the respective secondary burner members, and first and second control means to control the supply of fuel and oxygen to said respective first and second secondary burner members; first and second partitioning walls at the rear of said first and second primary chambers, wherein the tops of said partitioning walls define the bottom limits of said first and second transfer vents, respectively; first and second secondary heat transfer chambers in fluid communication with said first and second afterburner chambers, respectively, wherein heated gases flowing from the respective afterburner chambers cause heating of the respective secondary heat transfer chambers; wherein a heat conductive and refractive partitioning wall separates said first and second primary chambers one from the other; wherein a portion of each of said first and second primary chambers overlies the respective first and second secondary heat transfer chambers and are separated therefrom by a heat conductive and refractive horizontal partitioning member; and an exhaust duct disposed between said first and second secondary heat transfer chambers and in fluid communication with a vertically disposed exhaust stack for conducting exhaust gases away from said first and second secondary heat transfer chambers.
