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.
Claims60
A combustion system, comprising:
- a fuel and oxidant source configured to output fuel and oxidant;
- a plurality of perforated flame holders, including at least:
- a first perforated 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 perforated flame holder;
- and
- a second perforated 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 within the second perforated flame holder;
- the first and second perforated flame holders being separated by a gap.
