摘要： According to an embodiment, a burner system includes a pilot burner disposed in a furnace at a distal position along a main fuel and combustion air flow axis, and one or more main fuel nozzles disposed at a proximal position along the main fuel and combustion air flow axis. The pilot burner is configured to support a pilot flame and the one or more main fuel nozzles are configured to support a main flame in contact with the pilot flame. The pilot burner is disposed to cause the main fuel and combustion air to be ignited by the pilot flame. The pilot burner may support a diffusion pilot flame or may include a premixing apparatus to support a pre-mixed flame.

摘要： A combustion system includes a perforated flame holder, a camera, and a control circuit. The perforated flame holder sustains a combustion reaction within the perforated flame holder. The image capture device takes a plurality of images of the combustion reaction. The control circuit produces from the images an averaged image and adjusts the combustion reaction based on the adjusted image.
