Hydrocarbon specialist reduces carbon emissions with help from Buderus
Buderus stainless-steel condensing boilers have been installed to replace failing boilers in the 9-storey head office of M. W. Kellogg in Greenford. The existing boilers in the 16 500 m2 building were suffering from corrosion and showing signs of leaking. Scion recommended their replacement rather than remedial action. Kellogg is a full-service engineering, procurement and construction contractor primarily serving the hydrocarbon market.
Three Buderus SB 615 boilers with outputs of 650 kW were chosen to replace the existing system.
Malcolm Bavin of Scion says, ‘We were keen to specify high-quality boilers, with reliability and longevity being key factors.’
The new design incorporates an improved hydraulic layout using a low-loss header and individual shunt pumps for each boiler to replace the previous large common shunt pump. This arrangement simplifies control of the flow through the boilers, ensuring design conditions are met and achieving significant savings in electrical consumption.
Les Hill, building officer for Kellogg, says, ‘We wanted the latest in high efficiency to reduce carbon and NOx emissions compliant with the forthcoming Building Regulations upgrade due in 2010. We believe we have made all the right decisions to achieve this goal.’
The boilers installed are included in the Energy Technology List and so qualify for Enhanced Capital Allowances, which Kellogg has applied for.
