ABSTRACT OF THE DISCLOSURE Pieces of shredded tyres are fed into the top of a ver- tical pyrolysing furnace in a measured amount using a weighing hopper feed mechanism. Heated gas is introduced through inlet and pyrolysing the tyre pieces on a countercurrent flow principle to produce useful hydrocarbon volatiles and residues. The pyroly- sed residue including tyre reinforcing wires are efficiently re- moved from the furnace by a plurality of downwardly inclined screw conveyors disposed in throughs. Each screw conveyor extends into an inclined conduit and discharges into a vertical branch con- duit disposed at least partially within the cross-section of the furnace so that even discharge of the pyrolysed residue is ensured by the combined action of gravity and the screw conveyors.
