A pyrolysis waste-to-energy conversion system has a muffle furnace housing a rotating retort drum within the furnace and having an inlet sleeve and an outlet sleeve extending through inlet and outlet ends of the muffle furnace. A rotating retort drum drive applies rotary drive to the inlet rotating retort drum sleeves and an in-feed auger is within a tube within the inlet sleeve. An out-feed auger is within a tube within the outlet sleeve and arranged to deliver char and pyrolysis syngas to a char processing system and a syngas processing system. The inlet sleeve and said outlet sleeve are arranged to provide a gas seal to prevent air ingress or syngas egress to and from the rotating retort drum. A gas cleaning system has a cracking tower arranged to retain inlet gas at an elevated temperature for a residence time, and a gas quench and scrubber system.

A pyrolysis waste-to-energy conversion system (1) has a muffle furnace (3) housing a rotating retort drum (4) within the furnace and having an inlet sleeve (65) and an outlet sleeve (66) extending through inlet and outlet ends of the muffle furnace. A rotating retort drum drive (100) applies rotary drive to the inlet rotating retort drum sleeves and an in-feed auger (93) is within a tube (91) within the inlet sleeve. An out-feed auger (131) is within a tube (130) within the outlet sleeve (66) and arranged to deliver char and pyrolysis syngas to a char processing system and a syngas processing system. The inlet sleeve (65) and said outlet sleeve (66) are arranged to provide a gas seal to prevent air ingress or syngas egress to and from the rotating retort drum. A gas cleaning system (20) has a cracking tower (50) arranged to retain inlet gas at an elevated temperature for a residence time, and a gas quench and scrubber system (52). The cracking tower (50) comprises a mixing chamber (71) linked with a residence chamber (82). The mixing chamber has a burner for heat generation and an oxidant port arranged to mix and partially consume a portion of the gas as it passes through the chamber.
