An apparatus for pyrolysis and gasification of organic substances and mixtures thereof is provided with a pyrolysis reactor ( 1 ), a fluidized-bed firing ( 3 ) for pyrolysis residue, a reaction zone ( 2 ) for the pyrolysis gases ( 13 ) and circulating fluidized-bed material ( 35 ). The pyrolysis reactor ( 1 ) has a sluice for introducing application material ( 10 ) thereinto. An inlet for the fluidized-bed material ( 35 ) is disposed next to the combustion fluidized bed ( 3 ). Transport apparatus ( 14 ) for mixture of solid pyrolysis residue and circulating fluidized bed material ( 35 ) is disposed at or near a bottom of the fluidized bed ( 3 ) and lower end of the pyrolysis reactor ( 1 ). An overflow is situated at or near the top of the fluidized bed ( 3 ) while a heat transfer member is positioned within the reaction zone ( 2 ).
