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.
Claims14
A system for heating and pyrolyzing a fuel comprising:
- a gasifier;
- a syn-gas tube;
- a burner comprising a burner tube and an air intake tube that is the only source of air, said burner receiving a producer gas from the gasifier by way of the syn-gas tube;
- a combustion tube that serves as a location at which the fuel is pyrolyzed after the producer gas has been heated by the burner;
- an adjustment rod concentrically positioned within the air intake tube, traversing the length of the burner tube from a first end to a second end, and having a mechanism to vary a distance in which the adjustment rod protrudes from the burner tube at the first end;
- adjustment rod supports attached to, and traversing a radial distance between, the air intake tube and the adjustment rod, wherein the adjustment rod supports comprise a support block having a curved bearing surface which matingly engages an outer surface of the adjustment rod;
- and
- a column that transfers a load along its axial axis from the adjustment rod to the air intake tube, said column extending from said support block;
- wherein the combustion tube is fluidly connected to the syn-gas tube;
- and
- wherein an ambient air is sucked with negative pressure through the fuel.
A system for heating and pyrolyzing a fuel comprising:
- a gasifier;
- a syn-gas tube;
- a burner comprising a burner tube and an air intake tube that is the only source of air, said burner receiving a producer gas from the gasifier by way of the syn-gas tube;
- a combustion tube that serves as a location at which the fuel is pyrolyzed after the producer gas has been heated by the burner;
- an adjustment rod concentrically positioned within the air intake tube, traversing the length of the burner tube from a first end to a second end, and having a mechanism to vary a distance in which the adjustment rod protrudes from the burner tube at the first end;
- and
- weld nuts that secure the adjustment rod into a stable position;
- wherein the combustion tube is fluidly connected to the syn-gas tube;
- and
- wherein an ambient air is sucked with negative pressure through the fuel.

- an adjustment rod concentrically positioned within the air intake tube, traversing the length of the burner tube from a first end to a second end, and having a mechanism to vary a distance in which the adjustment rod protrudes from the burner tube at the first end;
- and
- mixing fins arrayed about a circumferential outer surface of the air intake tube to further facilitate mixing ambient air and fuel;
- wherein the combustion tube is fluidly connected to the syn-gas tube;
- wherein an ambient air is sucked with negative pressure through the fuel;
- and
- wherein the mixing fins have an adjustable pitch.
