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.
Claims33
A combustion system, comprising:
- a perforated flame holder, including:
- an input face,
- an output face on a side opposite from, and substantially parallel to, the input face, and
- a plurality of apertures extending between the input face and the output face;
- an electrically conductive erosion guard adjacent to the input face and configured to protect the perforated flame holder from erosion;
- an electrically conductive counter electrode adjacent to the output face;
- and
- a voltage source configured to generate a plasma within the perforated flame holder by applying a voltage between the erosion guard and the counter electrode.
