  • Patent number: 6953517
    Abstract: In order to make it possible for an inhomogeneous residue generated in a pyrolysis plant to be separated continuously and in as fully graded a way as possible, specially selected components are combined with one anther in an advantageous configuration. An essential element of the plant is the separation of a coarse residue in a coarse screen and the subsequent separation of the remaining residue in a zigzag separator into a light residue and a heavy residue. By use of the plant, in particular, the carbon-containing constituents are separated from the remaining residue. The individual components are mostly configured to be self-cleaning for fault-free operation.

  • Patent number: 6484882
    Abstract: In order to separate a carbon-containing fraction as completely as possible from a residue, for example a pyrolysis residue, a combustible constituent is first separated from a non-combustible constituent. A carbon-containing light fraction is subsequently separated from a small-fragment fraction of the non-combustible constituent. For this purpose, in a preferred embodiment, a combination of a facility for the separation of wire with a heavy-fragment separator following the latter is provided for a continuous separation operation. The carbon-containing fraction thus obtained is preferably supplied for further utilization to a combustion chamber of a pyrolysis plant.

  • Patent number: 5769007
    Abstract: A heating chamber or low-temperature carbonization drum has an interior receiving bulk material or trash and has a longitudinal axis about which the heating chamber or drum is rotatable. A number of heating tubes through which a heating gas can flow in a given direction, are disposed in the interior of the heating chamber or drum, are oriented approximately parallel to one another, and have an end region as seen in the given flow direction. Turbulators are disposed inside the heating tubes in the end region.
