Working in conjunction with two UK universities, Primasonics has succeeded in designing a ‘green’ range of acoustic cleaners.

Sonic sootblowers are an alternative to traditional steam sootblowers, which can be expensive to purchase, install, operate and maintain.

Fabricated from 316-grade stainless steel and fitted with a new design of wave generator the Quattro Range ensures maximum cleaning performance over a wide range of plant applications.

The Quattro Range of sonic sootblowers eliminates particulate build-up problems throughout key plant sectors.

Aimed at the multi-horn installations associated with the power generation, ESPs, boilers (power generation, industrial and marine) and baghouse applications, sonic sootblowers prevent ash build-up; provide 360deg total tube cleaning; ensure no risk of tube erosion or corrosion, or damage to the integral structure of the boiler of other plant structures; significantly reduce the risk of soot fires; prevent internal damage to ESPs caused by mechanical rapping; significantly increase filter bag life and eliminate hopper blockage; and require minimal maintenance.

Sonic sootblowing encompasses the realm of sound transmission through particulate and solids.

It is best described as the creation of rapid pressure fluctuations that are transmitted into the particulate or ‘bonded’ dry material, causing the solid particles to resonate and dislodge from the surface they are deposited on or bonded to without causing any structural damage to the plant.

Once dislodged, the materials fall due to gravity or are carried away by the gas or air stream within the process.

The powerful sound waves are produced when the short bursts of standard plant compressed air enters the sonic sootblower’s wave generator and forces the only moving part, an aerospace-grade titanium diaphragm, to flex, creating the powerful ‘base’ sound wave.

This ‘base’ tone is then transmitted by a range of different horn sections into selected fundamental frequencies between 75 and 350Hz.

A periodic ‘sounding’ – typically 5 to 10sec every 2-30min – is all that is required.

Primasonics International is currently the worldwide leader in acoustic cleaning technologies. Since it was founded in 1998, the company has continually won awards for innovative technology and export success.

Primasonics founder, Donald Cameron, has a lifetime experience in specialist materials processing industries and is renowned for his ability to develop innovative process challenge solutions. The Audiosonic range of acoustic cleaners was initially marketed with a four-model range. Its immediate industrial success linked to continuous R&D investment has lead to the planned expansion to an unbeatable seven-model range together with the widest range of installation options.

Primasonics is unique — the only company to specialise in the design, manufacture and supply of both audible and inaudible acoustic cleaning systems for the dry process, power generation, storage and transportation industries as diverse as petrochemical plants, cement plants, carbon black plants and the power generation industry. Primasonics acoustic cleaning systems can be used in a variety of applications such as silos, hoppers, boilers, ID fans, filters and many more. Our Primasonics personnel are always pleased to make site visits to provide a presentation on acoustic cleaner theory and application. We will also be pleased to carry out a site survey and provide a detailed technical report and recommendations.
