ABSTRACT:
A burner system is provided which creates standing waves in the gas/air flow within the burner so as to vary the pressure distribution along the length of the burner and thus the heights of the flames produced along the length of the burner. By changing the standing waves, the pressure distributions within the burner are changed, thereby causing the burner to produce changing flame patterns that simulate realistic wood burning flame patterns. In another embodiment, two orthogonal or sinusoidal gas/air flows offset by a phase angle are generated within the burner creating a beat frequency. By varying the phase angle offset, the rate of occurrence of the beats defining the beat frequency are varied resulting in the variation of the pressure distribution within the burner. Consequently, the flame patterns generated by the burner are varied simulating the appearance of realistic wood burning flame patterns.
