ABSTRACT:
A fluidized-bed reactor for the pyrolytic treatment of wastes containing hydrocarbons and a high content of polymeric organic substances includes a circumferential wall having an inner surface and an interior with a conical lower section and an expanded cylindrical upper section. Fluidizing-gas feed pipes have ends with lower circumferential sections protruding directly from the inner surface of the circumferential wall into the conical lower section. Covering walls covering the ends of the fluidizing-gas feed pipes and extend obliquely downwardly and inwardly. Blow orifices are each disposed at a respective one of the lower circumferential sections and have an obliquely downward and inward blow direction for blowing fluidizing-gas into a fluidized-bed material in the interior. Heating pipes for heating with heating gas dip vertically from above through the expanded cylindrical upper section of the interior. The heating pipes have connections for heating gas, combustion air and exhaust gas.
