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.
Claims58
A system configured for electrical control of a combustion reaction, comprising:
- a high voltage source in a region external to a combustion volume;
- a high voltage propagation path from the high voltage source to the combustion volume;
- and
- one or more electrodes disposed in the combustion volume, operatively coupled to the high voltage propagation path, and configured to (at least intermittently) apply an electrical signal to a flame supported by a burner in the combustion volume;
- wherein the high voltage propagation path includes an electrical bushing including a conductor, a dielectric insulator structure disposed peripheral to the conductor, and an electrical bushing coupling disposed peripheral to the dielectric insulator structure;
- and
- wherein the electrical bushing is configured for in-field installation or replacement.
A method for installing an electrode disposed relative to a flame in a combustion volume, comprising:
- inserting an electrode into a combustion volume through an aperture defined by a combustion volume coupling;
- coupling, to the combustion volume coupling, an electrical bushing including a conductor in electrical continuity with the electrode;
- and
- coupling an external terminal of the electrical bushing conductor to a high voltage source.
