Acoustic Cleaner

Acoustic Cleaner / Sonic Horn / Acoustic Soot Blower

Basic Principle

The basic principle of SonicCleaning is to create a sound wave carrying an energy level exceeding the forces that tend to make particles suspended in a gas flow to adhere to each other and the surrounding surfaces, i.e. preventing a build up by breaking up the particles before they can form a hard layer.
This is achieved by activating one or more sound emitters that radiate powerful sound signals at pre-determined intervals.


The pressure variations of the sound, will "rock" the individual ash particles, making them break away from each other.

2Reduction of boundary layer

When the sound waves are filling the volume, then the boundary layer above a surface is decreasing. This means that the flue gases will pass much closer to the surface that is intended to be kept clean. By doing this the flue gases will "blow away" the ash particles.
