PASSIVE ACOUSTICS PROCESS TO MONITOR FLUIDIZED BELL LEVEL |
摘要 |
A method is described for the non-intrusive determination of the bed level in two phase fluid bed reactor using wall vibrations of the reactor, which involves: measuring wall vibrations of the structure of the reactor at several vertically-separated positions along the wall thereof, and determining the power spectrum as a function of frequency. The area of the power spectrum under a resonance peak is determined for each position, and a change in the area of the power spectrum in the vertical sense is correlated with the bed level. |
