Abstract
An ionizer provides charged particles to charge a combustion reaction. A conductive flame holder cooperates with the charged combustion reaction to hold the combustion reaction away from a fuel nozzle. Dilution and/or premixing of the fuel in the region between the fuel nozzle and the conductive flame holder results in a reduced flame temperature. The reduced flame temperature results in a reduced output of oxides of nitrogen (NOx).
Claims20
An electrodynamic burner, comprising:
- a fuel nozzle configured to provide fuel to support a combustion reaction;
- an ionizer configured to generate charged particles, the ionizer being positioned away from the fuel nozzle and separated from contact with the combustion reaction by a charged particle transport path;
- and
- a first electrode configured as a conductive flame holder positioned to receive fuel from the fuel nozzle;
- wherein the ionizer is configured to cause charged particles to flow along the transport path to electrically charge the combustion reaction;
- and
- wherein the electrical charge carried by the combustion reaction is configured to cooperate with the conductive flame holder to hold the combustion reaction proximate the conductive flame holder.
