Abstract:
A combustion system includes a perforated flame holder, a fuel nozzle configured to output fuel toward the perforated flame holder, and a plasma ignition device configured to output a plasma during a preheating state of the combustion system and to cease outputting the plasma to transition from the preheating state to the standard operating state. In the preheating state the plasma ignition device causes a preheating flame of the fuel stream at a position between the fuel nozzle and the perforated flame holder. In the standard operating condition, the plasma is not present and the fuel stream impinges on the perforated flame holder. The perforated flame holder supports a combustion reaction of the fuel stream within the perforated flame holder when in the standard operating state.
