Abstract
A spiral, perforate ceramic baffle is placed into a heat exchanger in facing relationship with the burner and in an overhung relationship to the heat exchanger. A primary air/fuel mixture in the flame from the burner passes into the baffle drawing secondary air into the overhung portion of the baffle cooling the burner flame. Turbulence of the burner flame pattern in the baffle changes heat exchanger harmonic resonance and reduces burner noise.
