Abstract: A combustion system supports a combustion reaction. The combustion system utilizes a combustion sensor and a plasma generator to stabilize the combustion reaction. A controller receives sensor signals from the combustion sensor and controls the plasma generator to stabilize the combustion reaction responsive to the sensor signals. The plasma generator stabilizes the combustion reaction by generating a plasma.

Abstract: A system for measuring a fuel-oxidant equivalence ratio includes at least one wall defining a gas volume including fuel and air. A gas ionization source is configured to cause a formation of ions in the gas. A power supply is configured to output a time-varying voltage. A first electrode is disposed in the gas volume, operatively coupled to the power supply, and configured to carry the time-varying voltage. A second electrode is arranged to operatively couple to a signal output by the first electrode after the signal passes through the gas volume. Characteristics of the received signal indicate the fuel-oxidant equivalence ratio.

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 flame holder system includes a support structure configured to support a plurality of burner tiles within a furnace volume. The support structure includes a frame supporting a support lattice. A number of burner tiles are arranged in an array on the lattice. The support structure is configured to be assemblable without tools inside the furnace volume, using components that are sized to fit through an access port in a wall of the furnace.

Abstract: A combustion system includes a perforated flame holder and a preheating flame holder. During a preheating state, a preheating fuel nozzle outputs a preheating fuel stream onto the preheating flame holder and the preheating flame holder holds a preheating flame supported by the preheating fuel. The preheating flame heats the perforated flame holder to a threshold temperature. After the perforated flame holder has reached the threshold temperature, a fuel nozzle outputs a plurality of fuel streams including a fuel toward the perforated flame holder with a trajectory selected to entrain an oxidant with the fuel streams. The perforated flame holder supports a combustion reaction of the fuel and the oxidant.

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.
