Abstract: A burner includes a distal flame holder, first and second fuel nozzles, a fuel and oxidant source, and a mixing tube disposed upstream from the distal flame holder. Fuel emitted from the first fuel nozzle mixes with oxidant from the oxidant source to form a fuel and oxidant mixture to support combustion in the distal flame holder. A non-reactive fluid source such as recirculated flue gas provides a non-reactive fluid for dilution of the fuel and oxidant mixture to prevent flashback.

Abstract: A combustion system includes a fuel and oxidant source, a first distal flame holder body, a second distal flame holder body, and a thermal load. The fuel and oxidant source outputs fuel and oxidant. The first and second distal flame holder bodies simultaneously or alternately hold combustion reaction portions of the fuel and oxidant and/or of combustion products. The thermal load receives thermal energy from the first and second combustion reaction portions.
