Title: Furnace

Abstract

Pieces of shredded tires are fed into the top of a vertical pyrolyzing furnace in a measured amount using a weighing hopper feed mechanism. Heated gas is introduced through inlet and pyrolyzing the tire pieces on a countercurrent flow principle to produce useful hydrocarbon volatiles and residues. The pyrolyzed residue including tire reinforcing wires are efficiently removed from the furnace by a plurality of downwardly inclined screw conveyors disposed in troughs. Each screw conveyor extends into an inclined conduit and discharges into a vertical branch conduit disposed at least partially within the cross-section of the furnace so that even discharge of the pyrolyzed residue is ensured by the combined action of gravity and the screw conveyors.
