ATTENUATING COMBUSTION NOISE OF PREMIXED FLAMES

摘要

Disclosure is made of methods, systems, and apparatus for changing characteristics of noise of premixed flames supported on burners by heating burner passageways by an amount that attenuates combustion noises arising from premixed flames. Alternatively, attenuation occurs by controlling a temperature differential between a first point relative to a premixed flame and at least a second point in an uncombusted portion of a fuel/oxidizer mixture causing the flame.
