Abstract: Embodiments disclosed herein include flame holders that may provide recirculated fuel flow therethrough, combustion systems that include such flame holders, and related methods. A fuel and/or fuel-oxidant mixture may pass through one or more openings in the flame holder and, after combustion, the resulting flame may be held at or near a surface of the flame holder including in the one or more openings. Generally, the configuration of the flame holders disclosed herein (e.g., the one or more openings of the flame holders) may recirculate or regulate (e.g., decrease and/or increase) the flow of fuel and/or oxidant therethrough, at least limit flame flashback, improve fuel/oxidant mixing, increase flame stability, regulate where the flame is located in the flame holder, improve the operational stability window of the combustion system, or combinations of the foregoing.

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 low NOx burner includes a charging mechanism to charge a fuel stream or diluted fuel stream. A flame supported by the charged fuel stream can be held at a lifted location corresponding to high fuel dilution. If electrical power is lost or removed, the flame is shifted to a location corresponding to a lower fuel dilution.

Abstract: A high voltage electrical signal can be conveyed to an electrode in a combustion volume operatively coupled to a burner or a flame supported by the burner. A high voltage source in a region external to the combustion volume can convey the high voltage electrical signal to the electrode via a propagation path including an electrical bushing. The electrode and electrical bushing can be configured for field installation. Field installation can include a use of only simple tools.

Abstract: According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.
