Abstract: A system and method uses a combustor and gasifier to burn a primary dirty fuel, such as waste materials or high-polluting fossil fuels, and a secondary low-polluting fuel, such as biomass fuels, for co-generation of electricity while reducing harmful emissions. The primary fuel is burned at least partially through the use of an improved burner tube. Dirty exhaust from a combustor is scrubbed by a gasifier by reforming the combustors exhaust gases into a clean-burning producer gas (syn-gas). The secondary fuel and oxygen are added to the dirty exhaust in the gasifier to create gas, char and ash. The gas powers an engine or turbine that turns a generator, or a boiler, Stirling engine, or Organic Rankine Cycle power plant, and releases a cleaner exhaust.

Abstract: A gasifier system that combines the use of dirty fuels with clean fuels such as biomass. The heat created produces steam for the co-generation of mechanical power and electricity. The dirty fuels are converted in a gasifier or a pyrolyzer into various useful products that include syngas, heat, and oils. Syngas that is produced by the dirty fuels normally emits pollutants when combusted that require scrubbing. However, when the syngas is combusted into a biomass gasifier the dirty fuel emissions are scrubbed by being reformed into a much cleaner syngas/producer gas. Heat transferred from the dirty fuels gasifier/pyrolyzer syngas increases the efficiency of the clean fuels gasifier that results in increased amounts of steam for electricity/power production. In lieu of producing steam, the syngas from the clean fuel gasifier can be used to fuel an engine for power production. Other outputs from the clean-fuels gasifier include biochar and ash.

Abstract: The present invention includes a gasifier for gasifying fuels having a container with a top, sidewalls and a bottom for facilitating the gasifying process. One or more open vertical shafts extend downward inside the container for allowing a downdraft or updraft of air and fuel for the gasifying process. A rotating bed is preferably included inside the container and below the one or more shafts for receiving the fuel. The bed rotates essentially perpendicular to the shaft to facilitate even heating and gasifying of the fuel. The bed is further movable relative to the vertical shaft in order to increase or decrease the volume of fuel flow to the fuel.

Abstract: A method and apparatus for providing a steam boiler/combuster and gasifier that uses a primary dirty fuel, such as waste materials, or high-polluting fossil fuels, and a secondary low-polluting fuel, such as biomass fuels for co-generation of electricity while reducing harmful emissions. The primary fuel is burned in the combuster to create steam in the steam boiler. The steam turns a steam turbine thereby powering a first generator. The dirty exhaust from the combuster is scrubbed by a gasifier. The secondary fuel and oxygen are added to the dirty exhaust in the gasifier creating gas and ash. The gas powers an engine that turns a second generator and releases a cleaner exhaust.
