Abstract:
A combustion system includes a combustion reaction holder that defines plurality of combustion channels and a fluid volume separate from the plurality of combustion channels. The combustion channels are collectively configured to hold a combustion reaction. Heat from the combustion reaction is transferred to a fluid disposed in the fluid volume.
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 horizontally-fired flame burner includes a flame holder positioned laterally from the burner. The flame holder includes a plurality of perforations that collectively confine a combustion reaction of the burner to the flame holder.
Abstract:
A 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 furnace has a fuel and oxidant source to create a flow of combustible fuel/air mixture, a perforated flame holder on which the flow impinges, and a support structure to support the perforated flame holder in a position where it at least partially contains combustion of the fuel/air mixture. The support structure mechanically engages with the interior of the furnace to support the perforated flame holder, which may be movable within the furnace via a mechanism to optimize combustion or reduce NOx. The support may contain fluid coolant.
Abstract:
A down-fired flame burner includes a flame holder positioned below the burner. The flame holder includes a plurality of perforations that collectively confine a combustion reaction of the burner to the flame holder.
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:
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.
