  • Patent number: 4601730
    Abstract: A fixed bed gasifier for wood or other solid fuel has an air supply grate or grid spanning its interior horizontally substantially above the floor of the gasifier reactor vessel. The air supply tubes forming the grid are widely spaced apart to offer minimal resistance to the downward movement of ash in the reactor vessel. The ends of the grid tubes are supported by stuffing boxes on the side wall of the reactor vessel. An ash removal auger communicates with an ash pit at the bottom of the gasifier reactor vessel and a separately powered rotating ash plow operates in the ash pit above the ash removal auger and below the level of the air supply grate or grid.
