Claim 0:
1. A combustion system, comprising:
a pilot fuel distributor configured to support a pilot flame by outputting a pilot fuel into a furnace volume at least during a preheating state;
a main fuel distributor configured to output a main fuel into the furnace volume during a standard operating state;
a distal flame holder positioned in the furnace volume to be preheated by the pilot flame during the preheating state and to support a combustion reaction of the main fuel and an oxidant at least adjacent to the distal flame holder during the standard operating state;
a pilot flame sensor configured to sense a condition of the pilot flame and to output a sensor signal indicative of the condition of the pilot flame;
a distal flame holder sensor configured to sense a condition of the distal flame holder and to generate a sensor signal indicative of the condition of the distal flame holder;
one or more actuators configured to adjust a flow of the main fuel from the main fuel distributor and to adjust a flow of the pilot fuel from the pilot fuel distributor; and
a controller communicatively coupled to the actuators, the pilot flame sensor, and the distal flame holder sensor, the controller being configured to receive the sensor signals from the pilot flame sensor and the distal flame holder sensor and to control the actuators to adjust the flow of the pilot fuel and the main fuel responsive to the sensor signals and in accordance with software instructions stored in a non-transitory computer readable medium coupled to the controller.
