Title:
扁球型ガス化装置
Document Type and Number:
Japanese Patent JP4008034
Kind Code:
B2
Abstract:
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.
