Claim 32:
33. A computing system implemented method for operating a combustion system, the method comprising:
receiving, during a preheating state of a combustion system, sensor signals from a pilot flame sensor indicating a condition of a pilot flame in a furnace volume supported by a flow of pilot fuel and an oxidant;
receiving, during the preheating state, sensor signals from a distal flame holder sensor indicating a temperature of a distal flame holder positioned in the furnace volume to be preheated to an operating temperature by the pilot flame during the preheating state;
outputting control signals to control one or more actuators to adjust a flow of the pilot fuel, to adjust a flow of the oxidant, or to generate an electric arc to ignite the pilot flame responsive to the sensor signals from the pilot flame sensor and in accordance with software instructions stored on a non-transitory computer readable medium;
outputting control signals to control one or more actuators to transition the combustion system from the preheating state to a standard operating state if the sensor signals from the distal flame holder sensor indicate that the distal flame holder has reached the operating temperature, the standard operating state corresponding to supporting a combustion reaction of a main fuel and the oxidant in the distal flame holder and in accordance with the software instructions stored on the non-transitory computer readable medium;
receiving sensor signals from the distal flame holder sensor during the standard operating state indicating a condition of the distal flame holder; and
outputting control signals to control one or more actuators to adjust a flow of the main fuel or to adjust the flow of the oxidant responsive to the sensor signals from the distal flame holder sensor during the standard operating state and in accordance with the software instructions stored on the non-transitory computer readable medium.
