Abstract: A severe furnace vibration was developed in a gas-fired package boiler during an initial operation. The vibration occurred at higher loads and was characterized by an acoustic standing wave ...

Abstract: 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 ...

Abstract: Acoustic resonance or acoustic vibration, which develops in flow channels containing a tube bank, is caused by vortex shedding generated by crossflow over the tube bank. Transverse acoustic modes ...

Abstract: 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 ...

Abstract: Strong acoustic resonance with acoustic pressures reaching up to 165dB developed in the boiler bank of a package boiler at full load. At first, the resonance developed at a lower frequency ...

Abstract: Fatigue cracks from high cycle vibratory loading have developed in a centrifugal fan impeller after a relatively short period of operation. Based on vibration tests of the impeller and acoustic ...

Abstract: 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 ...

Abstract: Based on recent laboratory experimental data by (2004, “ The Effects of Duct Width and Baffles on Acoustic Resonance in a Staggered Tube Array,” in Proceedings of the Eighth International ...
