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.
Claims62
A combustion system, comprising:
- a fuel and oxidant source configured to output fuel and oxidant;
- a first flame holder positioned to receive a first portion of the fuel and oxidant and to support a first combustion reaction of the fuel and oxidant within the first flame holder;
- and
- a second flame holder positioned to receive a second portion of the fuel and oxidant and to support a second combustion reaction of the fuel and oxidant, the first and second flame holders being separated by a gap of non-zero width.

A method, comprising:
- supporting a first and a second flame holder in a furnace volume and separated by a gap;
- outputting fuel and oxidant from a fuel and oxidant source onto the first and second flame holders;
- sustaining a first combustion reaction of the fuel and oxidant within the first flame holder;
- and
- sustaining a second combustion reaction of the fuel and oxidant within the second flame holder.

A modular burner, comprising:
- a metal flange that is configurable for attachment to a furnace wall, the metal flange having an inner surface and an outer surface, and defining a flange aperture passing through the metal flange between the inner surface and the outer surface;
- a plurality of support legs, each operatively coupled to the metal flange and extending inwardly from the flange, each support leg being formed at least partially from a ceramic material;
- a flame holder operatively coupled to each of the plurality of support legs such that the support legs collectively support the flame holder at a distance from the metal flange;
- a combustion air register operatively coupled to the flange and disposed adjacent to the outer surface of the flange, the combustion air register being configured to control a flow of combustion air through the flange aperture to the flame holder;
- and
- a fuel delivery system including one or more fuel nozzles configured to deliver gaseous fuel toward the flame holder;
- wherein the flame holder is configured to hold a combustion reaction supported by a mixture of the gaseous fuel and the combustion air.
