    Abstract: A combustion system includes a fuel distributor configured to output a fuel, an oxidant source configured to output an oxidant, and a mixing tube defining a mixing volume aligned to receive the fuel and oxidant. The mixing tube is shaped to convey the fuel and the oxidant through the mixing volume at a bulk velocity higher than a flame propagation speed. The combustion system includes a flame holder aligned to receive the mixed fuel and oxidant and to support a combustion reaction of the fuel and the oxidant.

    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 system for electrically controlling a combustion flame may include a burner configured to generate the combustionflame. The combustion flame includes a resistance and a capacitance. The system may include an ionizer positioned proximate to the burner to supply ions of a first polarity to the combustion flame to charge the capacitance of the combustion flame to one or more voltage levels. The system may include a power supply coupled to the ionizer and configured to provide an output voltage signal of the first polarity to the ionizer to excite the ionizer to supply the ions of the first polarity to the combustion flame. The power supply may include a transformer and an output dampener operatively coupled in parallel to the transformer. The output dampener can suppress a second polarity of the output voltage signal to limit delivery of ions of the second polarity to the combustion flame by the ionizer.
