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.
