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: Embodiments of the invention are directed to a burner system including at least one Coanda surface and at least two electrodes that are biased in a manner to influences a location of fuel flow relative to the at least one Coanda surface and related methods. In an embodiment, a burner system includes at least one Coanda surface, at least one nozzle positioned and configured to emit a fuel flow at least proximate to the at least one Coanda surface, at least two electrodes, and a voltage source operably coupled to the at least two electrodes. The voltage source may be configured to bias the at least two electrodes to generate an electric field at least proximate to the at least one Coanda surface that influences a location of the fuel flow and/or a flame relative to the at least one Coanda surface.

Abstract: Technologies are provided for applying energy to a combustion reaction. For example, a method may include supporting a combustion reaction; applying energy to the combustion reaction via one or more control signals; detecting a change in one or more parameters associated with the combustion reaction; comparing the change in the one or more parameters to a database; determining whether the change in the one or more parameters corresponds to a change in the combustion reaction; selecting a change in the one or more control signals from the database; and applying the change in the one or more control signals to change the a value of the energy applied to the combustion reaction responsive to changes in the one or more parameters associated with in the combustion reaction.

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.
