  • COMBUSTION SYSTEM WITH A PERFORATED FLAME HOLDER AND AN EXTERNAL FLUE GAS RECIRCULATION APPARATUS
    Publication number: 20170051913
    Abstract: A combustion system includes a perforated flame holder positioned within a combustion volume, a nozzle configured to emit a fuel stream toward the perforated flame holder, an oxidant source configured to introduce an oxidizer fluid into the combustion volume, and a flue gas recirculation (FGR) channel having a first end in fluid communication with the combustion volume downstream of the perforated flame holder and a second end in fluid communication with the oxidant source. A controller is configured to hold a combustion parameter within a selected range of values by regulating a quantity of flue gas flowing in the FGR channel.

  • Burner with a series of fuel gas ejectors and a perforated flame holder
    Patent number: 9562682
    Abstract: A combustion system outputs fuel gas from a plurality of fuel ejectors toward a forward end of a burner wall and preheats a perforated flame holder by sustaining combustion reaction of the fuel gas at combustion zone between the burner wall and a perforated flame holder. The combustion system then outputs fuel gas from the fuel ejectors onto the perforated flame holder and sustains a combustion reaction of the fuel gas within the perforated flame holder.

  • ELECTRODYNAMIC BURNER WITH A FLAME IONIZER
    Publication number: 20160363317
    Abstract: An ionizer provides charged particles to charge a combustion reaction. A conductive flame holder cooperates with the charged combustion reaction to hold the combustion reaction away from a fuel nozzle. Dilution and/or premixing of the fuel in the region between the fuel nozzle and the conductive flame holder results in a reduced flame temperature. The reduced flame temperature results in a reduced output of oxides of nitrogen (NOx).
