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 gas turbine is configured to operate with a high temperature combustion gas stream. The gas turbine may include a combustor that provides a combustion gas stream including charged particles and at least one turbine stage including at least one high temperature surface that may be driven with a voltage selected to repel the charged particles. The at least one high temperature surface may output a film-cooling layer including cool air, the film-cooling layer being stabilized by Coulombic forces between the voltage and the charged particles.

Abstract: Combustion control electrode assemblies, combustion control systems using such assemblies, and methods of manufacturing and using such assemblies are disclosed. The electrode assemblies may include one or more electrodes including a sintered refractory metal material for heat and/or wear resistance. In an embodiment, an electrode assembly for a combustion control system may include at least one substrate and at least one electrode formed on the at least one substrate. The at least one electrode may include a sintered refractory metal material. The at least one electrode may be configured to be mounted proximate to or contacting a flame. The electrode assembly may further include at least one voltage source operatively coupled to the at least one electrode. The at least one electrode and the at least one voltage source may be collectively configured to apply an electric field to one or more regions at least proximate to the flame.
