Abstract: A combustion system includes a fuel and oxidant source, a first perforated flame holder, a second perforated flame holder, and a thermal load. The fuel and oxidant source outputs fuel and oxidant. The first and second perforated flame holders simultaneously or alternately hold combustion reactions of the fuel and oxidant and/or of combustion products. The thermal load receives thermal energy from the first and second combustion reactions.

CPC classification number: F23C5/06
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 combustion system includes a perforated flame holder, a preheating fuel distributor, a main fuel distributor, an oxidant source, an array of sensors, and a controller. The oxidant source outputs an oxidant. The preheating fuel distributor supports a preheating flame configured to preheat the perforated flame holder by outputting a preheating fuel when the combustion system is in a preheating state. The main fuel source outputs a main fuel in the standard operating state. The perforated flame holder is configured to support a combustion reaction of the main fuel and the oxidant in the standard operating state. The sensors are configured to sense parameters of the preheating flame and the perforated flame holder and to output sensor signals to the controller. The controller executes software instructions that include adjusting the flow of the main fuel, the preheating fuel, and the oxidant responsive to the sensor signals.

Abstract: A combustion system includes a perforated flame holder and a plurality of bluff body members positioned between the perforated flame holder and a fuel source. The fuel source outputs a fuel stream through gaps between the bluff body members toward the perforated flame holder. The perforated flame holder and the bluff body members collectively hold a combustion reaction supported by the fuel stream.
