ABSTRACT:
A pyrolysis gasifier includes a first auger (26) which moves carbon from a carbon collection tank (24) through an air lock valve (30) to a carbon holding tank (28). The gasifier includes an inner cylindrical sleeve (80) which is configured such that there is a small air gap between it and an interior wall of the gasifier (16). The air lock valve (30) includes an inlet member (96) which connects the housing to a connecting tube from the first auger (26). A plate (100) within the housing is mounted such that in a closed position, the plate is sealingly positioned against a lower edge of the inlet member (96), while in an open position, the plate is away from the inlet member, permitting carbon to move into the carbon holding tank. A fuel spreader apparatus 53 is positioned at the top portion of the gasifier. It includes a stirring rod (44) and two opposed fuel paddle assemblies (67, 69) at the lower end thereof to spread the fuel over the cross-sectional area of the gasifier.
