  • Patent number: 9541285
    Abstract: A system for thermally processing solid fuel to produce pyrolysis gases, syngas, tar, char, and/or torrefied products, which includes a bulk solids pump having a curved passage to move a feedstock therein and wherein the pump includes a spool supported for rotational movement. A sleeve shaped chamber or chambers surround all or a portion of at least an axial extent of said curved passage to permit containment of heated gases to heat solid fuel within the curved passage to thermally process the feedstock within the pump.
    Type: Grant

  • Patent number: 7784415
    Abstract: A method and apparatus for delivery of a solid particulate fuel to a heating system. The present invention provides a lock-up transport system to deliver particles of solid fuel in a downstream direction while maintaining the position of the particles relative to each other. The lock-up transport system provides a linear mass flow through the gasification stages of the fuel.
