摘要

The gasification of organic materials by air, comprises incompletely gasifying the organic materials to a raw product gas (5) in a first gasification reactor (3), so that a flying coke is obtained with a carbon portion of 30-60%, which is still sufficient to bind the mineral matrix, so that a slagging is prevented, separating the coke from the product gas by a cyclone, feeding the coke to a further reactor, where the coke is further gasified or burned and the emerging ash is taken away, and supplying the emerging gases to the first reactor. The gasification of organic materials by air, comprises incompletely gasifying the organic materials to a raw product gas (5) in a first gasification reactor (3), so that a flying coke is obtained with a carbon portion of 30-60%, which is still sufficient to bind the mineral matrix, so that a slagging is prevented, separating the coke from the product gas by a cyclone, feeding the coke to a further reactor, where the coke is further gasified or burned and the emerging ash is taken away, supplying the emerging gases to the first reactor and continuously supplying a further mineral or inflammable solid material into the further reactor in a quantity of 50 mass.% on the total mass. The separation of the coke from the product gas contained in the gasification of the organic material takes place in a fixed bed. The organic materials have low ash melting point at 300[deg] C. The gasification is carried out at 700-800[deg] C. The gasification is carried out under a pressure of 105> to 106> Pa. The gasification reactor is a Torbed (RTM: High rate gas-solid reactor). The final gasification of the coke takes place by oxygen content sufficient for complete combustion and is carried out in a further reactor with moved fixed bed on rust or in a retort fed by lower push. The gasification of the coke is carried out with fluidization with a reactor and the ash of the coke is separated from the produced gas with a downstream separator. The product gas from the further reactor is fed into the first reactor in raw, hot condition at 500-600[deg] C. The product gas is fed into the process after cooling and cleaning. An independent claim is included for a device for the gasification of organic materials by air.
