Abstract: 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.

Abstract: A method of operation of a burner system includes introducing a fuel stream into a perforated flame holder, combusting the fuel stream, with a majority of the combustion occurring between an input face and an output face of the flame holder, and producing a heat output from the combustion of at least 1.5 kBTU/H/in2.

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 flame holder assembly includes a flame holder element and a flame shield element. The flame holder element has a first plurality of apertures extending through the flame holder element. The flame shield element has a second plurality of apertures extending through the flame shield element. Each of the second plurality of apertures has a lateral dimension that is no greater than a flame quenching distance. The flame shield element is positioned facing the flame holder element, and the flame holder assembly is configured such that fuel is supplied to the flame holder element via the second plurality of apertures of the flame shield element.

Abstract: A cracking furnace includes a combustion volume defined in part by a burner wall having a refractory lining. A plurality of perforated flame holders is arranged in an array that is spaced away from the wall, with fuel input faces facing the wall. Each of a plurality of fuel nozzles is positioned and configured to emit a fuel stream toward the input face of a respective one of the plurality of perforated flame holders. Combustion reactions, supported by the fuel streams emitted by the fuel nozzles, and held by the flame holders, release heat, which is emitted by the flame holders as thermal (blackbody) radiation, a portion of which impinges upon, and heats the inner face of the refractory lining. Thermal radiation from the flame holders and the wall impinges upon a load positioned in the approximate center of the combustion volume, between burner walls.
