Abstract
A combustion system includes an electrically actuated flame location control mechanism.
Claims24
A system, comprising:
- an igniter flame nozzle configured to support an igniter flame in a combustion ignition position;
- and
- an igniter flame actuator configured to deflect the igniter flame between a first igniter flame position and a second igniter flame position;
- wherein the igniter flame actuator comprises:
- an igniter flame charge mechanism configured to apply an electrical charge to the igniter flame;
- and
- an igniter flame charge reaction mechanism configured to support a deflector charge selected to interact with the charge applied to the igniter flame.
4 more elements
A system, comprising:
- an igniter flame nozzle configured to support an igniter flame in a combustion ignition position;
- an igniter flame actuator configured to deflect the igniter flame between a first igniter flame position and a second igniter flame position;
- and
- a distal flame holder,
- wherein the first igniter flame position is selected to ignite a preheat flame supported by the fuel stream between the fuel nozzle and the distal flame holder.
2 more elements
A method of operating a combustion system, comprising:
- emitting, from a fuel nozzle, a main fuel stream toward a distal flame holder;
- preheating the distal flame holder by supporting an igniter flame in a first position to fully ignite the main fuel stream and to hold a resulting preheat flame between the fuel nozzle and the distal flame holder;
- and
- igniting a distal combustion reaction at the distal flame holder once the distal flame holder has reached an operating temperature.
