In the present paper the attention is focused on similarity between the phenomena of acoustic resonance which occurred in actual boiler plant and that of the two-dimensional model of boiler. We measured a gap velocity, sound pressure level, acoustic mode shape, spectrum and phase delay of velocity fluctuations in the tube banks. As a result it was made clear that the phenomenon of acoustic resonance in the model is similar with that of the actual plant. The relation between vortex shedding phenomena inside of in-line tube banks and acoustic resonance in the model was experimentally examined.
