Abstract:
A solid fuel combustion system includes a solid fuel burner configured to sustain a combustion reaction of a solid fuel and an oxidant. The solid fuel combustion system includes a first and a second electrode positioned to adjust a shape of a combustion reaction of solid fuel and an oxidant by generating an electric field.
Abstract:
A combustion system includes a perforated flame holder that includes a plurality of perforations and substantially contains a combustion reaction within the perforations. The system further includes one or more electrodes coupled to the perforated flame holder and configured to electrically influence the combustion reaction within the perforations.
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/in 2 .

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:
An electrically enhanced combustor includes bilayer insulation. A thermal insulator protects an electrical insulator from high temperatures that could cause the electrical insulator to become at least somewhat electrically conductive.
Abstract:
A high voltage can be applied to a combustion reaction to enhance or otherwise control the combustion reaction. The high voltage is switched on or off by a grid electrode interposed between a high voltage electrode assembly and the combustion reaction.
Abstract:
A corona electrode may be used to apply an electric field to a combustion reaction to cause a response in the combustion reaction. The corona electrode may include an ion-ejecting feature having a small radius.
Abstract:
A down-fired flame burner including a flame charger and one or more field electrodes configured to control flame shape and/or heat transfer to a chemical reactor is presented. Also described is a method for providing process heat includes projecting a down-fired flame in a heating volume, electrically charging the flame to carry a majority charge, and applying an electric field proximate the down-fired flame to control flame shape, heat transfer from the flame, or flame shape and heat transfer from the flame, and applying heat from the flame to a chemical reactor.
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.
Abstract:
Technologies are presented for applying electrical energy to a combustion reaction to produce agglomerated combustion particulates. For example, a system may include: one or more electrodes configured to apply electrical energy to a combustion reaction; a combustion zone configured to support the combustion reaction of a fuel at a fuel source; and an electrical power source operatively coupled to the one or more electrodes and configured to apply electrical energy to the combustion reaction. The combustion reaction is controlled to produce a distribution of agglomerated combustion particulates characterized by an increase in at least one of an average particulate diameter or an average particulate mass.
