    Abstract: A combustion system includes a perforated flame holder configured to hold a main combustion reaction substantially between input and output faces thereof. A main fuel nozzle is positioned to emit a main fuel stream toward the input face. An igniter assembly is configured to ignite a preheat flame supported by the main fuel stream between the main fuel nozzle and the perforated flame holder, and to selectably control a degree of ignition of the fuel stream by the preheat flame. During a start-up of the combustion system, the perforated flame holder is preheated by the preheat flame. When the flame holder reaches a start-up temperature, the preheat flame is shifted from fully igniting to partially igniting the fuel stream, allowing fuel and oxidant to reach the flame holder. A flame is ignited in the flame holder while the preheat flame burns. The preheat flame is then released.

    Abstract: A combustion system includes a perforated flame holder, an oxidant source, and an adjustable fuel nozzle. The oxidant source outputs oxidant. The adjustable fuel nozzle outputs fuel onto the perforated flame holder. The perforated flame holder supports a combustion reaction of the fuel and oxidant within the perforated flame holder. The position of the adjustable nozzle relative to the perforated flame holder can be adjusted to achieve selected characteristics of the combustion reaction within the perforated flame holder.

    Abstract: A combustion system includes a perforated flame holder, a preheating fuel distributor, a main fuel distributor, an oxidant source, an array of sensors, and a controller. The oxidant source outputs an oxidant. The preheating fuel distributor supports a preheating flame configured to preheat the perforated flame holder by outputting a preheating fuel when the combustion system is in a preheating state. The main fuel source outputs a main fuel in the standard operating state. The perforated flame holder is configured to support a combustion reaction of the main fuel and the oxidant in the standard operating state. The sensors are configured to sense parameters of the preheating flame and the perforated flame holder and to output sensor signals to the controller. The controller executes software instructions that include adjusting the flow of the main fuel, the preheating fuel, and the oxidant responsive to the sensor signals.
