Abstract:
A burner system that employs a perforated flame holder and is configured to combust a powdered solid fuel includes a structure configured to protect the perforated flame holder from erosion caused by particles of the solid fuel.
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 burner system includes a perforated flame holder configured to hold a combustion reaction and a plurality of fuel nozzles aligned to deliver respective fuel streams to the perforated flame holder.
Abstract:
A down-fired flame burner includes a flame holder positioned below the burner. The flame holder includes a plurality of perforations that collectively confine a combustion reaction of the burner to the flame holder.
Abstract:
A combustion system includes a combustion reaction holder that defines plurality of combustion channels and a fluid volume separate from the plurality of combustion channels. The combustion channels are collectively configured to hold a combustion reaction. Heat from the combustion reaction is transferred to a fluid disposed in the fluid volume.
Abstract:
A combustion system includes a fuel and oxidant source, a perforated flame holder, and a support structure that supports the perforated flame holder at a selected distance from the fuel and oxidant source. The fuel and oxidant source outputs fuel and oxidant onto the perforated flame holder. The perforated flame holder receives the fuel and oxidant and sustains a combustion reaction of the fuel and oxidant within the perforated flame holder.
Abstract:
A combustion fluid flow barrier includes an aperture to control combustion fluid flow. The combustion fluid is charged by a charge generator. The combustion fluid flow barrier includes at least one flow control electrode operatively coupled to the aperture and configured to selectively allow, attract, or resist passage of the charged combustion fluid through the aperture, depending on voltage applied to the flow control electrode.
Abstract:
A flame holder system includes a support structure configured to support a plurality of burner tiles within a furnace volume. The support structure includes a frame supporting a support lattice. A number of burner tiles are arranged in an array on the support lattice. The support structure is configured to be assemblable without tools inside the furnace volume, using components that are sized to fit through an access port in a wall of the furnace.
