Abstract
A duct burner includes a perforated flame holder and a fuel header that is spaced away from the perforated flame holder and has a plurality of fuel nozzles. Each of the fuel nozzles is arranged to emit a fuel stream toward a respective portion of the perforated flame holder. A combustion reaction supported by the fuel streams is held within a plurality of apertures extending through the perforated flame holder.
Claims34
A system, comprising:
- a transport duct configured to carry a gaseous fluid;
- and
- a burner positioned inside the transport duct, the burner including:
- a perforated flame holder having a first face, a second face lying opposite the first face, and a plurality of apertures extending through the perforated flame holder between the first and second faces, and
- a fuel nozzle positioned and configured to emit a fuel stream toward the first face of the perforated flame holder.

A duct burner, comprising:
- a perforated flame holder having a first face, a second face lying opposite the first face, and a plurality of apertures extending through the perforated flame holder between the first and second faces, the first face having an aspect ratio of greater than 2:1;
- a fuel header spaced away from, and extending substantially parallel to a long dimension of the first face of the perforated flame holder;
- and
- a plurality of fuel nozzles distributed along the fuel header, each configured to emit a fuel stream toward a respective portion of the first face of the perforated flame holder.
1 more element
A method, comprising:
- supporting a combustion reaction substantially within a plurality of apertures extending through a perforated flame holder positioned within a fluid transport duct by introducing a fuel stream to a first face of the perforated flame holder;
- and
- transferring heat produced by the combustion reaction to a gaseous fluid flowing in the transport duct past the perforated flame holder.
