... a burner axis. Theoretical predictions indicated that the thermoacoustic behavior of the burner/furnace system operated in an unstable range explaining the underlying cause of the vibration problem. For the elimination of the vibration problem, a two-step solution was envisioned: (1) The mode of fuel...

...Frantisek L. Eisinger; Robert E. Sullivan Seven burner/furnace systems, three of which vibrated and four of which did not vibrate in operation are evaluated for thermoacoustic oscillations. The evaluation is based on the Rijke and Sondhauss models representing the combined burner/furnace (cold/hot...

...Frantisek L. Eisinger, Mem. ASME; Robert E. Sullivan, Mem. ASME Thermoacoustic combustion oscillation and vibration experienced in a gas turbine at operation is reported. The oscillation manifested itself at two distinct frequencies representing the first and second mode frequencies of the combined...

...Frantisek L. Eisinger, Mem. ASME; Robert E. Sullivan, Mem. ASME Burner/furnace systems are generally sensitive to thermoacoustic vibration due to the presence of large temperature differentials between the cold burner air and the hot furnace gases. The systems are predicted to vibrate when...
