CMS Acoustic Solutions reduces noise emissions at Cottam power station
CMS Acoustic Solutions has helped Vinci Services to soundproof its Flue Gas Desulphurisation (FGD) project at Cottam power station, by recommending Damping Sheet DS03 and Damping Compound Type DC to insulate critical noise areas.
FGD units were installed at Cottam to remove sulphur dioxide from flue gases before their release into the atmosphere. Vinci Services consulted CMS Acoustics to identify a solution that would prevent noise from these units affecting surrounding villages.
Damping Compound Type DC was applied to an aluzinc raw gas duct within the FGD unit. This water-based, polymeric emulsion inhibits the build up of resonant vibrations and efficiently reduces levels of radiated noise.
To soundproof the induced draft (ID) fan, Damping Sheet DS03 was installed. Manufactured from a mixture of bitumen, plasticizers and elastomers, Damping Sheet DS03 is a self-adhesive backed material. Designed to insulate sound in industrial areas, it adheres directly to formed steel and aluminium panels.
Commenting on the project, Joe Hendry, Vinci Services, said: "The ID fan is an integral part of the sulphur dioxide removal process but it is particularly loud, so an effective soundproofing solution was needed. Damping Sheet DS03 was easy to install, provided a cost-effective solution and exceeded our specification to use a sheet of at least 2mm in thickness.”
Paul Absolon, technical director at CMS Acoustic Solutions, commented: “CMS Acoustics has extensive experience in overcoming acoustic challenges for industrial applications. Our portfolio offers the full range of high performance and specialist acoustic products and we can always deliver the most appropriate solution at the best price.”
Damping Sheet DS03 is easy to cut and install. Provided in black, it is available in four standard weights and can be used with metal panels of varying thicknesses.
Applied at a 3mm thickness, the spray grade damping compound is ready for use and is directly put onto metal or plastic. This user-friendly emulsion dries quickly between applications and can be protected by most types of paint.
