Method and device for pyrolyzing and gasifying organic substances or substance mixtures

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).
