Abstract:
A burner system includes a plurality of burners, each having a nozzle positioned to emit a stream of fuel into a combustion volume, and a perforated flame holder, including a plurality of apertures extending between first and second faces thereof, and positioned to receive a stream of fuel from the respective nozzle. In operation, the flame holders are configured to hold a flame substantially within the plurality of apertures.
Abstract:
A combustion system may include a plurality of heated volume portions. At least two of the plurality of heated volume portions may include corresponding respective electrodes. The electrodes may be driven to produce respective electric fields in their respective volumes. The electric fields may be configured to drive desired respective responses.
Abstract:
A combustion system such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
Abstract:
A premixed fuel and air combustion system includes an anti-flashback electrode configured to repel a charge concentration in a combustion fluid and reduce or prevent the flame from flashing back into a mixer.
Abstract:
A burner includes a porous flame holder configured to support a combustion reaction to achieve a very low output of oxides of nitrogen (NOx).
Abstract:
According to an embodiment, a combustion system is provided, which includes a nozzle configured to emit a diverging fuel flow, a flame holder positioned in the path of the fuel flow and that includes a plurality of apertures extending therethrough, and a preheat mechanism configured to heat the flame to a temperature exceeding a startup temperature threshold.
