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.
Claims20
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;
- and
- adjustable mixing fins arrayed about a circumferential outer surface of the air intake tube to further facilitate mixing ambient air and fuel, wherein the mixing fins are removable such that a number of the mixing fins can change after an initial assembly onto the air intake tube;
- wherein the combustion tube is fluidly connected to the syn-gas tube.

- adjustable mixing fins arrayed about a circumferential outer surface of the air intake tube to further facilitate mixing ambient air and fuel, wherein the mixing fins are removable such that a number of the mixing fins can change after an initial assembly onto the air intake tube;
- wherein an ambient air is sucked with negative pressure through the fuel.
A burner comprising:
- a burner tube;
- an air intake tube that is the only source of air, said burner receiving a producer gas by way of a syn-gas inlet;
- a combustion tube fluidly connected to the syn-gas inlet, the combustion tube serving as a location at which the fuel is pyrolyzed after the producer gas has been heated by the burner;
- and
- adjustable mixing fins arrayed about a circumferential outer surface of the air intake tube to further facilitate mixing ambient air and fuel, wherein the mixing fins are removable such that a number of the mixing fins can change after an initial assembly onto the air intake tube.
