Patent ID: 7214252

Claim:
An apparatus for the carrying out of a method for the pyrolysis and gasification of organic substances or mixtures of organic substances, comprising a pyrolysis reactor ( 1 ), a fluidized-bed firing ( 3 ) for the pyrolysis residue, a reaction zone ( 2 ) for the pyrolysis gases ( 13 ), a fluidized-bed material ( 35 ) circulation between the combustion fluidized-bed ( 3 ) and the pyrolysis reactor ( 1 ), said pyrolysis reactor ( 1 ) being a shaft or rotary reactor, comprising a sluice for introducing application material ( 10 ) thereinto, an inlet for the fluidized bed material ( 35 ) into said pyrolysis reactor ( 1 ) from the combustion fluidized bed ( 3 ), disposed next to the combustion fluidized bed ( 3 ); the pyrolysis reactor ( 1 ) having a transport apparatus ( 14 ) arranged for transporting a mixture of solid pyrolysis residue and the circulating fluidized bed material ( 35 ) into a bottom or location near the bottom of the combustion fluidized bed ( 3 ) and disposed towards the bottom of said fluidized bed ( 3 ), from a lower end of said pyrolysis reactor ( 1 ) and disposed underneath the lower end of said pyrolysis reactor ( 1 ); the combustion fluidized bed ( 3 ) having an overflow situated at or near a top of said fluidized bed ( 3 ) and said pyrolysis reactor ( 1 ) and arranged for transferring the circulating fluidized bed material ( 35 ) into the pyrolysis reactor ( 1 ) and to be constantly filled with the circulating fluidized bed material ( 35 ); said reaction zone ( 2 ) comprising a heat transfer member ( 2 ) connected to the pyrolysis reactor ( 1 ) for receiving the pyrolysis gases ( 13 ) from the pyrolysis reactor ( 1 ) and to which waste gases ( 37 ) from the combustion fluidized bed ( 3 ) are supplied for heat exchange with the pyrolysis gases ( 13 ); and said overflow positioned immediately underneath said heat transfer member ( 2 ) in said reaction zone ( 2 ) of said fluidized bed reactor ( 3 ) and downwardly sloping to said pyrolysis reactor ( 1 ).
