Abstract: A combustion system includes a perforated flame holder, an oxidant source, and an adjustable fuel nozzle. The oxidant source outputs oxidant. The adjustable fuel nozzle outputs fuel onto the perforated flame holder. The perforated flame holder supports a combustion reaction of the fuel and oxidant within the perforated flame holder. The position of the adjustable nozzle relative to the perforated flame holder can be adjusted to achieve selected characteristics of the combustion reaction within the perforated flame holder.

Abstract: A combustion system includes a fuel and oxidant source that outputs fuel and oxidant, a first perforated flame holder, and a second perforated flame holder separated from the first perforated flame holder by a gap. The first and second perforated flame holders sustain a combustion reaction of the fuel and oxidant within the first and second perforated flame holders.

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.

CPC classification number: F23C99/001
Abstract: A combustion system includes a burner assembly, an electrode positioned within a combustion volume and configured to apply electrical energy to a flame supported by the burner assembly, and a dielectric electrode support extending through a furnace wall into the combustion volume and configured to support the electrode and further configured to be cooled by a coolant fluid circulated therethrough. The electrode support has coolant ports in fluid communication with a coolant channel extending within electrode support. During operation of the combustion system, a fluid coolant flows through the electrode support, holding a temperature of the electrode to within a selected range.

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 perforated 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.
