Abstract:
A burner supporting primary and secondary combustion reactions may include a primary combustion reaction actuator configured to select a location of the secondary combustion reaction. A burner may include a perforated flame holder structure configured to support a secondary combustion reaction above a partial premixing region. The secondary flame support location may be selected as a function of a turndown parameter. Selection logic may be of arbitrary complexity.
Abstract:
A fire tube boiler includes a perforated flame holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
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).
Abstract:
A combustion system includes a perforated flame holder, a camera, and a control circuit. The perforated flame holder sustains a combustion reaction within the perforated flame holder. The image capture device takes a plurality of images of the combustion reaction. The control circuit produces from the images an averaged image and adjusts the combustion reaction based on the adjusted image.

Abstract:
An electrically enhanced combustor includes bilayer insulation. A thermal insulator protects an electrical insulator from high temperatures that could cause the electrical insulator to become at least somewhat electrically conductive.
Abstract:
In a combustion system, a charge source is configured to cooperate with a collection plate and a director conduit to cause at least one particle charge-to-mass classification to be reintroduced to a flame for further reaction.
Abstract:
A flare stack burner includes a fuel stack housing in which a fuel nozzle and a perforated flame holder are positioned. The fuel nozzle is configured to emit a fuel stream toward the flame holder.
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 combustor may include a nonmetallic combustor body configured to hold a combustion reaction and one or more electrodes disposed outside the nonmetallic combustor body and configured to apply electrical energy to the combustion reaction.
