Claim 34:
35. A system for controlling a combustion system, the system comprising:
at least one processor; and
at least one memory coupled to the at least one processor, the at least one memory having stored therein instructions which, when executed by any set of the one or more processors, perform a process including:
causing the combustion system to enter a preheating state by controlling one or more actuators to initiate a pilot flame supported by a flow of pilot fuel and an oxidant and configured to preheat a distal flame holder to an operating temperature;
receiving sensor signals from a pilot flame sensor indicating a condition of the pilot flame;
receiving sensor signals from a distal flame holder sensor indicating a condition of the distal flame holder;
controlling the one or more actuators to adjust the flow of the pilot fuel, to adjust a flow of the oxidant, or to activate an igniter if the sensor signals from the pilot flame sensor indicate a predetermined condition of the pilot flame;
causing the combustion system to transition 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, by controlling the one or more actuators to stop the flow of the pilot fuel and to initialize a flow of a main fuel, the distal flame holder being configured to support a combustion reaction of the main fuel and the oxidant during the standard operating state; and
controlling the one or more actuators to adjust the flow of main fuel or to adjust the flow of the oxidant if the sensor signals indicate a predetermined condition of the distal flame holder or the combustion reaction.
