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 gaslifier 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.
Claims20
A burner comprising:
- a cylindrical body having a first end, a second end, a circumferential outer surface, an inlet for receiving fuel on the circumferential outer surface, and an outlet for dispensing fuel near the second end;
- an air intake tube concentrically positioned within the cylindrical body, traversing a length of the cylindrical body from the first end to the second end, and having an inlet for receiving ambient air near the first end of the cylindrical body;
- an adjustment rod concentrically positioned within the air intake tube, traversing the length of the cylindrical body from the first end to the second end, and having a mechanism to vary a distance in which the adjustment rod protrudes from the cylindrical body at the first end;
- and
- a mixing plate attached to the adjustment rod near the second end, the mixing plate adapted to facilitate mixing ambient air and fuel;
- wherein:
- (i) the air intake tube is the only source of air;
- (ii) the ambient air is sucked with negative pressure through the fuel;
- (iii) the fuel is heated and pyrolyzed, forming gas for a gasification process.
A method of combustion comprising:
- receiving gaseous fuel at an inlet of a burner tube;
- receiving ambient air at an inlet of an air intake tube, said air intake tube concentrically positioned within the burner tube;
- adjusting a distance in which a rod protrudes from the burner tube at one end to adjust a position of a mixing plate operatively attached to the burner tube at the other end;
- mixing the fuel and the ambient air, at least in part, with the mixing plate to form a more efficient mixture of resulting gas and air;
- and
- igniting the resulting mixture of gas and air to burn more efficiently;
- wherein:
- (i) the air intake tube is the only source of air;
- and
- (ii) the ambient air is sucked with negative pressure through the fuel;
- (iii) the fuel is heated and pyrolyzed, forming gas for a gasification process.
