Acoustic horns and cleaning systems are designed to produce low frequency, high volume sound waves for the purpose of moving dust or soot particles. In practice one or more horns are inserted into a vessel and the dust or soot particles are subjected to sound blasts frequently enough to not allow heavy deposits to form.

For
successful acoustic cleaning several requirements must be
met:
|
- The build up
has to be dry and powdery.
- The interval
between sound blasts must be short enough to ensure that
a significant buildup of dust or soot has not occurred,
and that the duration of the sound blast is long enough
to fill the whole vessel and break the particles adherence.
Usually the starting point for most applications is 10 second
duration every 10 minutes.
- The horns require
between 40-80 SCFM of air at 70-90 PSI. The volume and pressure
must be at these levels or greater to ensure that the horns
emit sound efficiently.
- The vessel the
horns are being installed on, must be clean and free of
deposits. The goal of the horns is to have a short enough
interval to keep the vessel clean.
