Abstract
In a fuel and oxidant combustion system, a flame holder support structure includes a heating element that receives electrical energy from an electrical power source. The heating element is raised to an auto-ignition temperature of a fuel and oxidant mixture directed, along an axis proximate the flame holder support structure, to a flame holder for combustion thereof.
Claims43
A burner system, comprising:
- a fuel and oxidant source configured to output a fuel and oxidant mixture along an axis;
- a flame holder spaced away from the fuel and oxidant source, and positioned to receive the fuel and oxidant mixture;
- a flame holder support structure operatively coupled to the flame holder;
- and
- an electrical power supply operatively coupled to the flame holder support structure and configured to provide electrical energy to at least a portion of the flame holder or the flame holder support structure;
- wherein the flame holder support structure comprises a heater configured to employ the electrical energy to raise the temperature of the flame holder at least to a temperature corresponding to an auto-ignition temperature of the fuel and oxidant mixture.
3 more elements
A method of stabilizing a flame in a burner system, the method comprising:
- supplying electrical energy to a flame holder support structure configured to physically support a flame holder spaced a distance from a fuel and oxidant source, the flame holder support structure disposed between the flame holder and the fuel and oxidant source;
- raising the temperature of the flame holder support structure, using the electrical energy, at least to a temperature corresponding to an auto-ignition temperature of the fuel and oxidant mixture;
- directing a fuel and oxidant mixture along an axis, the fuel and oxidant mixture being supplied by the fuel and oxidant source;
- and
- receiving the fuel and oxidant mixture at the flame holder.
2 more elements
A method, comprising:
- supporting, with a flame holder support structure, a flame holder in a position to receive fuel and oxidant from a fuel and oxidant source;
- raising a temperature of the flame holder to an auto-ignition temperature of the fuel and oxidant with an electrical heating element adjacent to the flame holder;
- outputting the fuel and oxidant from the fuel and oxidant source after the flame holder has reached the auto-ignition temperature;
- and
- supporting a combustion reaction of the fuel and oxidant with the flame holder.
