Dynamic Pressure Measurements of a Hot Gas Filter as a Diagnostic Tool to Assess the Time Dependent Performance

U. Rhyner, O. Rueda, S.M.A. Biollaz, R. Mai & H. Leibold
Dynamic pressure measurements are introduced as a powerful tool to detected filter failures at early stage. Filter failures such as leakages and blockages can be detected during back pressure recleaning pulses. High frequency sensors enable the recording of the recleaning pressure pulse. Patchy cleaning and depth filtration can be detected much faster with dynamic pressure measurements than with differential pressure measurements. Parameters derived from dynamic pressure data can be observed over time and compared with...
