Abstract

A combustion system includes a perforated flame holder and a plurality of bluff body members positioned between the perforated flame holder and a fuel source. The fuel source outputs a fuel stream through gaps between the bluff body members toward the perforated flame holder. The perforated flame holder and the bluff body members collectively hold a combustion reaction supported by the fuel stream.
