Abstract: A combustion system includes an ionizer configured to eject charges (or accept charges) for uptake by a combustion reaction to cause a combustion reaction to carry a majority charge or voltage. The ionizer includes an inner electrode, a dielectric body surrounding the inner electrode, and one or more conductive or semi-conductive inner electrodes disposed on the surface of the dielectric body. The inner and outer electrodes are configured to be in a capacitive relationship.

Abstract: A burner system and a retrofit flame control system for an existing burner system are disclosed. The burner system may include burner components, electrodynamic components, and a data interface. The data interface may receive a command for controlling the burner components and prepare a command for controlling the electrodynamic components at least partially based on the command for controlling the burner components.

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 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.
