Abstract: A downdraft gasifier and method of gasification with high yield biochar that utilizes a plurality of high throughput, vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. A rotating and vertically adjustable rotating grate is located beneath the reduction zone of the gasifier. In addition, a drying zone is located above the pyrolysis zone so the heat of the gasifier can be used to dry feedstock before it enters the gasifier. By optimizing the grate height and rpm, feedstock retention time in the drying zone, the drying zone temperature and feedstock moisture content, the result is gasification of biomass with a high yield and continuous biochar production.

Abstract: A downdraft gasifier that utilizes a plurality of vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. The shape of the tubes eliminates the need for a restriction (hearth), which limits the maximum achievable throughput. A rotating and vertically adjustable grate is located beneath, but not attached to, the reduction zone of the gasifier.

Abstract: A method and device for combustion of liquid fuels is presented which uses a plurality of rotating hydrogen flames to blast atomize and ignite a mechanically dispersed stream of the liquid fuel. This combustion method and device are particularly suited for heavy oil fuels, such as vegetable oils, which are not well burned using conventional burner technologies. This combustion method involves establishing a zone of combusting hydrogen and projecting a mechanically atomized dispersion of the liquid fuel into and through this zone of combusting hydrogen. The combusting hydrogen partially vaporizes and ignites the liquid fuel while the intense turbulence of the hydrogen combustion zone further disperses any remaining liquid fuel droplets. Once ignited and dispersed, the fuel oil continues to burn as it moves away from the hydrogen combustion zone.
