Abstract

Beschrieben wird ein Verfahren zur Erzeugung eines stickstoffarmen, bzw. nahezu stickstofffreien Gases durch Vergasung heterogener, biogener Brennstoffe, Reststoffe und/oder Kunststoffe in einem Reaktor umfassend eine Vergasungs- und eine Verbrennungszone, wobei der Reaktor ein fluidisiertes Bettmaterial aufweist, welches kontinuierlich in erhitztem Zustand von der Verbrennungszone in die Vergasungszone und von der Vergasungszone im abgekühlten Zustand zusammen mit nicht vergasten Restbrennstoff zurück in die Verbrennungszone geführt wird, dadurch gekennzeichnet, dass der Brennstoff in die als zirkulierende Wirbelschicht ausgebildete Vergasungszone eingebracht wird, wobei ein Teil der Wirbelschicht als Wanderbett ausgelegt ist, der Brennstoff in der zirkulierenden Wirbelschicht der Vergasungszone bei Luftabschluss unter Bildung eines Produktgases zumindest teilweise ent- bzw. vergast wird und der verbliebene bzw. nicht umgesetzte Restbrennstoff zusammen mit dem abgekühlten Bettmaterial über das Wanderbett in die Verbrennungszone verbracht wird, wo das Bettmaterial unter Bildung eines schnellen Wirbelbettes fluidisiert, durch Verbrennung des Restbrennstoffes wieder erhitzt und in die zirkulierende Wirbelschicht der Vergasungszone rückgeführt wird. Weiters wird eine Vorrichtung zur Durchführung dieses Verfahrens beschrieben.

Disclosed is a method of producing a low nitrogen gas by gasification of heterogeneous biogenic fuels, residues and / or plastics in a reactor comprising a gasification zone and a combustion zone, the reactor having a fluidized bed material continuously in a heated state is passed from the combustion zone into the gasification zone and from the gasification zone in the cooled state together with non-gasified residual fuel back into the combustion zone, characterized in that the fuel is introduced into the formed as a circulating fluidized bed gasification zone, wherein a part of the fluidized bed is designed as a moving bed , the fuel in the circulating fluidized bed of the gasification zone at Luftabschluss to form a product gas is at least partially degassed or gasified and the remaining or unreacted residual fuel together with the cooled Bettmate Rial over the moving bed is brought into the combustion zone, where the bed material fluidized to form a fast fluidized bed, reheated by combustion of the residual fuel and recycled to the circulating fluidized bed of the gasification zone. Furthermore, an apparatus for carrying out this method will be described.
