Abstract

Acoustics can primarily be defined as the discipline that deals with the creation, reception, transmission, control, and properties of sound, where mechanical waves propagate in an elastic medium such as solids, gases, and liquids. Such mechanical waves transfer energy from one point to another without inducing permanent displacement on the medium. As such, waves do not transfer mass but energy, therefore, mass is only moved perpendicular in the direction of propagation. Based on the scientific principles of acoustics technology, many industrial plants have adopted this form of technology for internal substructure cleaning methodologies of plant equipment. This form of cleaning methodology is known as either acoustic cleaning or sonic cleaning. An acoustic cleaning device is utilized to inhibit particulate material accumulation on various plant equipment such as boiler units, ducts, hoppers, and electrostatic precipitators. Surface cleanliness is maintained without intrusion into the internal substructure of plant equipment.  This paper reports on the state or arts in the development of the acoustics cleaning technology.
