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.
Claims38
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;
- 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;
- and
- a support structure supporting the first and second flame holders in a furnace volume, the support structure having a plurality of tube segments forming a single continuous tube, the first and second flame holders being positioned on the plurality of tube segments.

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;
- 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;
- and
- a modular burner, the 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, the first flame holder and the second flame holder being operatively coupled to each of the plurality of support legs such that the plurality of support legs collectively support the first flame holder and the second flame holder at respective distances 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 holders;
- wherein the fuel and oxidant source includes a fuel delivery system including one or more fuel nozzles configured to deliver gaseous fuel toward the flame holder;
- and
- wherein the first flame holder and the second flame holder are configured to hold a combustion reaction supported by a mixture of the gaseous fuel and the combustion air.
