Acoustic cleaning is based on high-energy sound waves generating pressure differences on dust and ash particles.
By constantly switching direction, the waves exert power on each individual particle, eventually shaking them loose from the surface. Depending on local conditions, the detached particles are then carried away with waste gas or by gravity.
At the core of the acoustic cleaner is a generator. A prestressed membrane between the lid of the acoustic cleaner and the body of the generator is made to vibrate using compressed air, which generates sound waves.
