    摘要: Apparatus and method for gasification of feedstock materials are disclosed. The apparatus includes an oblate spheroid (egg-shaped) gasification chamber having inlets for feedstock material and gaseous oxidizer. A combustion gas outlet permits removal of combustion gases, and an ash collection region allows collection and removal of ash produced in the gasification chamber. A plurality of recirculating venturi tubes located within the gasification chamber recirculate combustion gases and particulates into and out of a gasification zone. Each venturi tube includes a plenum having a gaseous oxidizer inlet and a plurality of orifices capable of producing high velocity air flow towards the feedstock material bed in the gasification zone. Filtration action of the bed entrains combustion particulates. A plurality of air cannons coupled to one or more pulse valves provide pulsed air flow into the gasification zone to agitate the feedstock material bed. Gaseous oxidizer inlets in the ash collection region allow control of the ash carbon content. Advantageously, the gasification device does not have moving internal parts. The agitation and recirculation is controlled by the gaseous oxidizer pulses and input into the gasification chamber.

    摘要: Apparatus and method for gasification of waste are disclosed. Waste material is fed to the top of a first combustion chamber, and a burning, rotating annular column of waste is supported in the combustion chamber. Combustion air is introduced to the first combustion chamber at or below the support for the burning annular column of waste so that the combustion air moves upwardly through the burning column. Combustion gases are withdrawn from the top portion of the first combustion chamber. Particulates are removed and recirculated to the first combustion chamber. The combustion gases are then fed to the top portion of a second combustion chamber. Secondary combustion air and optional fuel are fed to the second combustion chamber to complete the gasification process. A relatively clean producer gas is withdrawn from the bottom portion of the secondary combustion chamber.
