  • Selectable dilution low NOx burner
    Patent number: 9803855
    Abstract: A burner supporting primary and secondary combustion reactions may include a primary combustion reaction actuator configured to select a location of the secondary combustion reaction. A burner may include a lifted flame holder structure configured to support a secondary combustion reaction above a partial premixing region. The secondary flame support location may be selected as a function of a turndown parameter. Selection logic may be of arbitrary complexity.
    Type: Grant
    Filed: February 14, 2014
    Date of Patent: October 31, 2017
    Assignee: CLEARSIGN COMBUSTION CORPORATION

  • ELECTRODYNAMIC COMBUSTION SYSTEM WITH VARIABLE GAIN ELECTRODES
    Publication number: 20150219333
    Abstract: Technologies are presented for selecting an electrode gain value for applying electricity to control a combustion reaction. For example, a system can include one or more electrodes, an electrode gain selector configured to select an operative electrode gain value for the one or more electrodes, and a power supply operatively coupled to the one or more electrodes. The power supply can be configured to apply the electricity to the combustion reaction via the one or more electrodes at the operative electrode gain value.

  • HIGH VELOCITY COMBUSTOR
    Publication number: 20150121890
    Abstract: A combustor provides reaction anchoring by injecting a voltage or charge into an exothermic reaction such as aflame, and anchoring the exothermic reaction to a conductive surface positioned adjacent to a fuel jet nozzle.

  • GAS TURBINE AND GAS TURBINE AFTERBURNER
    Publication number: 20150107260
    Abstract: A gas turbine afterburner includes a gutter electrode that helps to hold an afterburner flame. A charge source applies a majority charge to be carried by a turbine exhaust gas. Electrical attraction between the majority charge and the gutter electrode helps to hold the afterburner flame.
