Summary
A Biomass Waste Combined Heat and Power(CHP) EFW facility located in Slough, Berkshire which supplies 80 MWe to the National Grid and heat to local sources and has an annual fuel tonnage requirement of over 150,000 tonnes per annum[1]. The facility is a 'multifuel' site using a variety of Municipal Solid Waste. Commercial and Industrial Waste and Wood Waste as its fuel sources[2].
In 2008 Scottish and Southern Energy (SSE) acquired Slough Heat and Power (SH&P) from SERGO for £49.25m[3].
The plant was converted to renewable fuel in c.2001 at a cost of approximately £30m[4] and this led to the development of an innovative, integrated supply chain for secure fuel supply in partnership with local suppliers such as Thames Valley Energy, a not-for-profit renewable energy agency[4].
The plant supplies all of the business located on the same trading estate as SH&P with heat, electricity and hot water. Over 2000 nearby homes are also supplied with their electricity from the plant via 100 km of underground cable as part of a private electricity network[4].
Plant
The six boilers and turbines at the SH&P energy centre can operate on a wide variety of fuels, ranging from renewable sources such as wood and fibre through to natural gas, coal and distillate. A small amount of natural gas and coal is used to control the boilers. As part of the plant, steam from two wood-fired fluidized bed boilers is directed to a 35 MW pass out steam turbine. A new multi-fuelled vibrating grate boiler dedicated to burning Fibre Fuel and wood chip, was commissioned based on a contract under the 4th Non-Fossil Fuel Obligation scheme[4].
The total electrical output of the combined system is 50 MWe of which 40 MWe comes from wood chips and 10 MWe from waste derived fuel (Fibre Fuel) in addition to 20 MWth[4].
Local Authority Users
In addition to any local authority users the companies and businesses located on the same trading estate as SH&P can direct their waste wood, non-recyclable paper, packaging and cardboard to the SH&P plant, thus reducing waste disposal costs and diverting a reusable resource from consuming landfill space. Fibre Fuel Limited, a subsidiary company of SH&P, coverts this non-recyclable fibre, such as waxed cardboard, laminates, photographic paper and mixed papers, into fuel cubes. To improve the calorific value of the fibre fuel, non-PVC plastics are added, up to a volume of 15%. The Fibre Fuel cubes are then used in the SH&P plant, a process which avoids 100,000 tonnes of material being disposed of in landfill[4].
