<p>A pyrolysis system (10) has carriers (28, 32-44, 50) that convey scrap (70) along a track (20, 22, 24) from an intake chamber (12) through an evacuated pyrolysis chamber (14) to a discharge chamber (16). The intake chamber (12) has a port (26) for receiving a carrier (28) and another port (30) for transferring the received carrier (28) to the pyrolysis chamber (14). Multiple carrier (32-44) accumulate in the pyrolysis chamber (14) and move in succession toward the discharge chamber (16). Conduits (58, 60) extending through the pyrolysis chamber (14) are heated with combustible gas flows to produce radiant heat. Reflectors (66, 68) are located on opposing sides of the internal zone (76) containing the conduits (58, 60) and carriers (32-44) to focus radiant onto the scrap (70). The discharge chamber (16) has a port (46) for receiving a carrier (50) from the pyrolysis chamber (14) and another port (48) for removing the received carrier (50). The ports (26, 48) isolate the intake and discharge chambers (12, 16) from the ambient environment when a carrier is transferred to or from the pyrolysis chamber (14) and the chambers (12, 16) are evacuated before such transfers. The intake and discharge chambers (12, 16) are vented to the atmosphere before receiving or discharging a carrier.</p> |
