  • Publication number: 20240084206
    Abstract: A biomass gasifier for producing syngas. The biomass gasifier includes a first tube having an air distribution manifold that extend within the gasification chamber. The first tube is rotatably positioned within a second tube, where the second tube is connected to a mixer below the air distribution manifold. The first tube has an air passage that is fluidly connected to an air source to deliver air to the combustion chamber through a plurality of air outlets within the air distribution manifold for distribution. The first tube is independently rotated from the second tube to evenly distribute air within the combustion chamber and the second tube with the mixer are rotated to agitate the biomass within the combustion chamber once a desired operating temperature range within the combustion chamber has been achieved.

  • Patent number: 10047308
    Abstract: A gasifier system for reducing the particle size of non-gas byproducts of the gasification process. The gasifier system generally includes a grinder that permits uninterrupted syngas flow during gasification of biomass that contains high amounts of silica and/or salts. The described system and method incorporates a grinder that breaks apart the resultant non-gas byproducts into finer particles that may be flushed out of a gasifier using the syngas stream. The particles may then be easily separated from the gas stream in a separator and collected in a char or waste bin for removal/disposal.

  • Patent number: 9567539
    Abstract: Apparatuses, systems, mobile gasification systems, and methods for gasifying residual biomass are described. An example system may include a mobile gasification system configured to gasify feedstock generated from residual biomass to provide syngas. The mobile gasification system may be configured to generate electrical power using the syngas. The mobile gasification system may be configured to be installed in a transportable structure.

  • Publication number: 20160068770
    Abstract: Apparatuses, systems, staging hoppers, and methods for controlling continuous feed of feedstock into a gasifier are described. An example method staging feedstock in a staging hopper of a gasification system, and activating a stirrer to provide the feedstock to from the staging hopper to a gasifier of the gasification system. The gasifier is configured to gasify the feedstock to produce syngas.
