1. A combustion system, comprising:
a fuel and oxidant source configured to output a flow of fuel and oxidant along an axis;
a first distal flame holder body aligned to receive at least a portion of the flow of fuel and oxidant from the fuel and oxidant source;
a second distal flame holder body aligned to receive a fluid flow from the first distal flame holder body, the fluid flow including at least one of the flow of fuel and oxidant received by the first distal flame holder body, a flow of combustion products produced by combustion adjacent to the first distal flame holder body from the received flow of fuel and oxidant, and a flow including a mixture of fuel and oxidant and combustion products; and
a thermal load disposed peripherally to the axis and the first and second distal flame holder bodies.
