Energy Ltd (MEL) is a joint venture between SSE plc and Wheelabrator
Technologies Inc. Their £300 million power generation plant at Ferrybridge in
West Yorkshire has a capacity of around 68MW of low carbon electricity using a
range of fuel sources, including up to 675,000 tonnes per year of waste-derived
fuels from various sources of municipal solid waste, commercial and industrial
waste and waste wood. The main contractor was Hitachi Zosen Inova
(HZI), a leading global energy from waste engineering contractor. Construction
began in October 2012, and the plant became fully operational in July 2015.
The Client's Needs
waste is shredded and transferred to a bunker from which it is fed to the
combustion zone of a 5-pass high pressure boiler to raise steam to power a
turbine generator boiler. Make-up water for the boiler has to meet a very high
quality specification of conductivity <0.1µS/cm, silica <5µg/kg and
dissolved organic carbon (DOC) <0.1µg/kg.
