  • Patent number: 11221073
    Abstract: Systems and methods for sealing a static or rotary tube to a rotary tube that is part of a thermal unit performing an airless or oxygen starved high-temperature incineration process like pyrolysis. Embodiments comprise a seal comprising a bearing assembly suspended on gimbals, the bearing assembly comprising an outer housing supporting therebetween a plurality of support rollers in contact with a rolling seal disk disposed between the flanges of the tubes. Embodiments comprise features that aid in preventing the bad effects of high temperatures and axial thrust loads of the tubes, including coordinating beveled portions on the support rollers and rolling seal disk. Embodiments comprise features for modularity and ease of maintenance, including gland plates, bore holes for oil and/or grease.

  • Patent number: 10823404
    Abstract: Systems and methods for processing a waste stream for feeding into a thermal unit performing an airless or oxygen starved incineration process like pyrolysis. Embodiments comprise an inlet hopper for receiving a waste stream, an inlet hopper lid, a slide gate that when closed forms the base of the inlet hopper and when open allows the waste stream to pass into an intermediate hopper, a ram body that when closed forms the base of the intermediate hopper and when open allows the waste stream to pass into a ram cylinder, a crusher plate on the front face of the ram body, a ram for driving the ram body and its crusher plate forward into the waste within the cylinder, a compactor cone comprising teeth for splitting, and an outlet through which the crushed and split waste stream exits the system into a thermal unit.

  • Patent number: 10428952
    Abstract: Systems and methods for sealing a static or rotary tube to a rotary tube that is part of a thermal unit performing an airless or oxygen starved high-temperature incineration process like pyrolysis in such a way that the joining of the tubes does not interfere with the oxygen controlled processes within the rotating thermal unit tube. Embodiments comprise a seal comprising chambers for sealing material supported by rollers contacting flanges of rotating tube elements and suspended by gimbals to permit the seal to move in a transverse direction, to swing, and to rotate while maintaining the seal.
