EDF Energys 1300MW Combined Cycle Gas Turbine (CCGT) power station at West Burton, Nottinghamshire features 40,000m2 of Tata Steel Acoustic Structural Liner Tray Built Up System, for high sound reduction and absorption levels in three giant turbine halls, as well as Colorcoat Prisma®.
CCGT power generation is the most energy efficient and clean method of fossil fuel generation. CCGT plant burn natural gas, which turns a gas turbine with the waste heat used to turn a steam turbine.
The roof and wall constructions feature the Tata Steel HL130/600 0.75mm gauge acoustic structural liner tray. This provided perforation over 27.3% of the exposed area of the tray to aid internal noise attenuation, enhancing the internal environment for workers.
Forming the base of a roof and wall construction incorporating two dense mineral fibre insulation layers, HL130/600s inherent properties greatly assisted sound reduction and absorption, simultaneously controlling noise breakout and reducing internal high and low frequency noise levels in the three halls.
A sound reduction figure of 36dB was achieved in each of the halls, significantly reducing their acoustic impact in the surrounding area.
The built up roofing and cladding system included a rigid mineral fibre slab in the pans of the HL130/600 structural liner tray.
A further semi-rigid mineral fibre slab was inserted above the tray flanges. This was separated from the rigid insulation layer by a flat 0.7mm galvanised steel sheet, helping to provide vital mass in the built-up system.
The external roofs feature the Tata Steel R32 profile. The external walls are clad in the C32 profile. Both products have a 0.7mm Colorcoat Prisma® Silver Metallic finish, plus a Denim finish on the lower levels of C32. Versatile, lightweight and strong, Colorcoat Prisma® is an ideal choice when it comes to exposed external environments like West Burton.
Offering outstanding UV resistance, Colorcoat Prisma® gives first-class colour and gloss retention, following comprehensive natural weathering testing in a variety of contrasting climates.
