  • Low emissions burner with premix flame stabilized by a diffusion flame
    Patent number: 7524186
    Abstract: A low emissions burner includes a diffusion burner surrounded by an annular array of premix burners. The diffusion burner operates at maximum swirl air flow and at a low constant fuel rate to reduce NOx emissions. The diffusion burner provides a stable swirling diffusion flame. An annular array of premix burners surrounds the diffusion burner and provides a non-swirling premix flame about the diffusion flame to advantageously provide a higher heat content about the periphery of the burner flame to facilitate industrial drying processes using the burner. The diffusion burner flame maintains the premixed flame stabilized. Water injection nozzles are provided each of the premix and diffusion burners.
    Type: Grant
