Method and apparatus for automated, modular, biomass power generation

An automated gasification reactor apparatus for converting a solid, carbonaceous material to a fuel gas, comprising:

• a heat source configured to ignite the solid, carbonaceous material to form a fuel gas;
• a plurality of injection tubes penetrating a gasification reactor wall at more than two levels, the injection tubes configured to deliver an oxidizing gas to an interior of a gasification reactor chamber at varying distances from the gasification reactor wall in a pattern that uniformly distributes the oxidizing gas within a fuel bed;
• and
• a moveable grate located at a downstream outlet of the gasification reactor chamber, the grate configured to crush frangible char or ash to a particle that is sized to pass through a mesh screen;
• wherein the plurality of injection tubes comprise a plurality of nozzles configured to deliver the oxidizing gas in a direction generally non-perpendicular to a direction of flow of the fuel gas.
