The Biomass industry is just one of many that can benefit from our sound solution A sound solution to ash build up in biomass power plants By Donald F Cameron stablished in 1998, Primasonics® International Ltd is the worldwide leader in design, manufacture and supply of Acoustic Cleaning Systems and Technologies. Our products are used in a variety of industries such as Power Generation, Cement, Petro Chemical, Food, Gypsum, Carbon Black, Chemical, and many more. E Acoustic technology, a green, nonpolluting efficient means to prevent ash build up - and it is certainly proving to be the case! Claymark based in Rotorua, New Zealand are specialists in milling, manufacturing and distribution of high quality timber products. This non-intrusive, affordable technology can increase the efficiency of process plant, provide improved thermal conductivity, prevent material blockage and remove particulate build up wherever ash, dust, powders or granular materials are processed, generated, stored or transported. The Biomass industry is just one of many that can benefit from our sound solution, yet there is a unique synergy between the technologies that seems to make a perfect combination – Biomass a green, low carbon footprint alternative to burning coal in power generation plants and Primasonics 38 PECM ssue 15 the timber drying kilns. The company needed to find an innovative, effective and environmentally friendly solution and so made initial contact with Primasonics International. We recommended the installation of two Acoustic Cleaners with a 230 Hz frequency to be sounded together. In addition, to comply with local plant noise regulations, acoustic covers were designed and installed. After three months operation an inspection was made and no ash build up was found on the boiler tubes. The total project cost was easily fully recouped within the first year of operation and Claymark now have an efficient, green and environmentally friendly solution to their previous serious ash build up. The problem they faced was essentially fouling of the biomass/wood waste fired boiler which provided hot water to Email: [email protected] Tel: +44 (0)17684 80372 www.primasonics.com
