Abstract: A combustion fluid flow barrier includes an aperture to control combustion fluid flow. The combustion fluid is charged by a charge generator. The combustion fluid flow barrier includes at least one flow control electrode operatively coupled to the aperture and configured to selectively allow, attract, or resist passage of the charged combustion fluid through the aperture, depending on voltage applied to the flow control electrode.

Abstract: A combustion system includes a perforated flame holder configured to hold a main combustion reaction substantially between input and output faces thereof. A main fuel nozzle is positioned to emit a main fuel stream toward the input face. An igniter assembly is configured to ignite a preheat flame supported by the main fuel stream between the main fuel nozzle and the perforated flame holder, and to selectably control a degree of ignition of the fuel stream by the preheat flame. During a start-up of the combustion system, the perforated flame holder is preheated by the preheat flame. When the perforated flame holder reaches a start-up temperature, the preheat flame is shifted from fully igniting to partially igniting the fuel stream, allowing fuel and oxidant to reach the perforated flame holder. A flame is ignited in the perforated flame holder while the preheat flame burns. The preheat flame is then released.

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 burner system and a retrofit flame control system for an existing burner system are disclosed. The burner system may include burner components, electrodynamic components, and a data interface. The data interface may receive a command for controlling the burner components and prepare a command for controlling the electrodynamic components at least partially based on the command for controlling the burner components.

Abstract: A burner system includes a fuel nozzle, an electrode configured to apply electrical energy to a combustion reaction supported by the fuel nozzle, a high-voltage converter configured to receive electrical energy from a low-voltage power supply and to provide high-voltage power to the electrode, a battery charger, and a switch module coupled to the battery charger, the converter, and first and second batteries. The switch module is selectively switchable between first and second conditions. In the first condition, the first battery is coupled to the battery charger and decoupled from the high-voltage converter, while the second battery is coupled to the high-voltage converter and decoupled from the battery charger. In the second condition, the first battery is coupled to the high-voltage converter and decoupled from the battery charger, while the second battery is coupled to the battery charger and decoupled from the converter.
