<p>An apparatus for pyrolyzing comminuted tire materials, the apparatus comprising an elongated pyrolysis chamber 12 having an inner surface and one or more inlets for introducing the comminuted tire materials; a conveyor 18 for continuously conveying the comminuted tire materials and pyrolysis products thereof through the pyrolysis chamber while substantially simultaneously removing build-up of the tire material and the pyrolysis products from the inner surface of the pyrolysis chamber; means for maintaining a temperature within the pyrolysis chamber at a level sufficiently high to pyrolyze at least some of the feed material to gaseous hydrocarbons; an outlet 38 from the pyrolysis chamber for discharging the gaseous hydrocarbons; wherein the conveyor 18 comprises a helical, center-less screw mounted for rotation at a first end within the pyrolysis chamber and having an unsupported second end, the helical center-less screw comprising a helical bar having a rectangular cross section providing a surface adapted to displace build-up of tire material and pyrolysis products from the inner surface of the pyrolysis chamber; characterized in that the apparatus further comprises a motor-driven agitator 52 positioned in a conduit 40 operatively connected to the outlet for discharging gaseous hydrocarbons separated from the non-volatile pyrolized material, the motor-driven agitator adapted to displace any condensate formed in the conduit.</p> |
