Abstract:
An charge element disposed proximate to a combustion reaction is caused to carry a voltage while also being prevented from arc-discharging or arc-charging to or from the combustion reaction, by a current limiting element in electrical continuity with the charge element.
Abstract:
A combustion system such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
Abstract:
A combustion system includes an electrodynamic combustion control system that provided for electrical control of a combustion reaction. Energy is received wirelessly, and electrical energy is generated from the wirelessly received energy. The electrical energy is applied to the combustion reaction in order to control or regulate operation of first and/or second electrodes configured to apply the energy to the combustion reaction.
Abstract:
A selective catalytic reduction system (SCR) or selective non-catalytic reduction (SNCR) system include a reagent charging apparatus configured to apply one or more electrical charges to a NOx reducing reagent. The electrical charges enhance mixing of the reagent with fluids carrying NOx and/or enhance reactivity of the reagent with NOx.
Abstract:
A combustion system includes a subsystem for electrically biasing or charging a flame and a virtual electrode launcher configured to launch a virtual electrode in proximity to the flame or combustion gas produced by the flame.
Abstract:
An apparatus for enhancing flame radiation includes a flame charging system and an electrically isolated electrode. A time-varying voltage is applied to the flame charging system and the flame charging system imparts a corresponding time-varying charge or time-varying voltage onto the flame. The flame responds to the time-varying charge or voltage by increasing its luminosity.
Abstract:
Technologies are presented for selecting an electrode gain value for applying electricity to control a combustion reaction. For example, a system can include one or more electrodes, an electrode gain selector configured to select an operative electrode gain value for the one or more electrodes, and a power supply operatively coupled to the one or more electrodes. The power supply can be configured to apply the electricity to the combustion reaction via the one or more electrodes at the operative electrode gain value.
Abstract:
A burner includes a flame positioning mechanism. The flame positioning mechanism includes a flame charger, a plurality of electrodes placed a respective distances along a fuel stream propagation path, and an electrode switch configured to place a subset of the plurality of electrodes into electrical continuity with a holding voltage. Current flow between the flame charge and the holding voltage anchors the flame to an electrode placed into electrical continuity with the holding voltage.
Abstract:
In an embodiment, a burner system is configured to control a geometry of a flame. The burner system includes electrodes configured to have a polarity selected to interact with a flame that has been charged with a charger to control at least one geometric characteristic of the flame.
