Abstract:
A combustor may include a nonmetallic combustor body configured to hold a combustion reaction and one or more electrodes disposed outside the nonmetallic combustor body and configured to apply an electric field, an electric field effect, charged particles, or voltage to the combustion reaction.
Abstract:
An electrically stabilized burner is configured to support a combustion reaction such as a combustion reaction substantially at a selected fuel dilution and with a mixing rate selected to maximize the reaction rate without quenching the combustion reaction.
Abstract:
A perforated flame holder and burner including a perforated flame holder provides reduced oxides of nitrogen (NOx) during operation. The perforated flame holder includes a pattern of elongated apertures extending between a proximal and a distal surface of the flame holder relative to a fuel nozzle. The perforated flame holder can provide a significantly reduced flame height while maintaining heat output from the burner.
Abstract:
A combustion system such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
Abstract:
A gas turbine may include turbine blades configured to improve stream adhesion by selectively attracting or reducing repulsion of charged particles carried by a combustion gas stream. According to an embodiment, a gas turbine may include a combustor configured to output a combustion gas stream, the combustion gas stream being controlled or driven to at least intermittently or periodically include charged particles having a first sign. For example the first sign may be positive during at least an instant. The gas turbine also includes at least one turbine configured to receive the combustion gas stream (carrying the charged particles at least intermittently or periodically). The turbine includes at least one turbine stage having turbine blades. Each turbine blade includes a repelling surface configured to be at least intermittently or periodically held or driven to a repelling voltage having a polarity the same as the charged particles having the first sign.
