Fault detection of Boiler Tube Using Vibration Signature

Onset of Nucleate Boiling Detection in a Boiler Tube by …

7/5/2018 · In this paper, a nonstationary vibration analysis method based on Morlet wavelet transform is presented for detection of onset of nucleate boiling (ONB) in a boiler tube. Comparison of the results by wavelet transform and visual observation of the ONB shows the capability and accuracy (less than 3% difference) of the proposed technique for detection of ONB in a boiler tube.
