Does the acoustic cleaning cause some risks to boiler structures?
– Nirafon acoustic cleaners use only acoustic frequencies (audible to human ear 16…16000Hz). The natural frequency of boiler structures is below this acoustic level. Frequencies below 20 Hz could cause the structures to resonate because of the sound and cause some risk to the structures, open bolts, cracks in welds etc. Acoustic frequencies which Nirafon uses, how ever, do not have any harmful effect to the structures. – Compared to steam soot blowing and water cleaning acoustic cleaning does not have the same harmful effects to the heat transfer surfaces as steam soot blowing; no erosion, which is caused by the ash particles in the steam wearing the surfaces or erosion caused by water. – Nirafon acoustic cleaners use only acoustic frequencies (audible to human ear 16…16000Hz).
