Claim 34:
35. A combustion system, comprising:
a fuel distributor configured to output a fuel;
an oxidant source configured to output an oxidant;
a mixing tube defining a mixing volume and being aligned to receive the fuel and the oxidant through an input opening thereof, the mixing tube being shaped to convey the fuel and the oxidant to an output opening thereof located at an output end of the mixing tube; and
a flame holder including:
a central portion facing the output end of the mixing tube; and
a peripheral flame holding portion at least partially surrounding the mixing tube and being positioned, outside of the mixing tube, along a non-zero length of the output end of the mixing tube from the output opening of the mixing tube and spaced a non-zero lateral distance away from an outer wall of the mixing tube about the non-zero length, the central portion and the peripheral flame-holding portion each being aligned to receive respective portions of a mixture of the fuel and the oxidant and to support a combustion reaction of the mixture of the fuel and the oxidant within or adjacent to the flame holder.
