Abstract: An apparatus for separating components of batches of waste rubber by pyrolysis comprises at least one heating chamber interconnected with a condenser by a conduit. The heating oven is provided with a plurality of cooperating heating elements, an inlet for receiving waster rubber, and an outlet for egress of pyrolyzed gaseous components. The condenser condenses and separates cooled liquid components from the gaseous components. Separated gaseous components are exhausted from the condenser. Cooled liquid components are conveyed from the condenser to a re-circulation tank. The conduit is provided with a pair of opposed injectors adjacent the outlet of the heating oven. A re-circulation line interconnects the re-circulation tank with the injectors and is provided with a pressurizing device for injecting cooled liquid components through the injectors into the conduit in the form of intersecting liquid laminar sheets thereby applying a vacuum draw on the egressing pyrolyzed gaseous components.
