Abstract: 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.
