Cottam
Location: Nottinghamshire
Operator: EDF Energy
Configuration: 4 X 500 MW
Fuel: bituminous coal, biomass
Operation: 1969-1970
Boiler supplier: John Thompson
T/G supplier: EE
Quick facts: Cottam is on a 620ac site on the west bank of the
River Trent, 8mi from the market town of Retford. At the end
of Dec 2000, Powergen closed on the sale of Cottam to London Electricity
for $593.5mn cash. In Dec 2002, RWE Industrie-Losungen GmbH from
Duisburg, Germany, signed the first of two contracts for the installation
of Thyssen wet limestone FGD systems at Cottam. Two of the
four systems came online during 2005, the third in 2006, and the final unit
in Oct 2007. The FGD project cost
£108mn. 25ha of short rotation coppice (SRC) willow has been
planted on Strawson’s Knightwood Trust Farms in fields directly adjacent
to the power station. In three years time, the willow will be harvested
into a carbon neutral wood chip and supplied as Koolfuel for co-firing
with coal.

West Burton
Location: Nottinghamshire
Operator: EDF Energy
Configuration: 4 X 500 MW
Fuel: bituminous coal
Operation: 1967-1968
Boiler supplier: ICL
T/G supplier: EE
Quick facts: In Jun 2000, work got underway on
a £100mn FGD retrofit project at West Burton. The turnkey contractor for
the installation of the MHI wet limestone systems was FLS Miljo. Contractors Arup Energy and Mowlem formed a
design-build partnership to undertake civil works and related
infrastructure. The total project was completed in the fall of 2003. SOFA
firing systems are being installed on all four units and will be completed
by 2008. In July 2004, GE Energy was awarded one of the first contracts in the EU to help meet the lowered
NOx emission limits set by the EU Large Combustion Plant Directive for
2008. The target limit for the new installations is 400 mg/m3 for a broad
range of coals, 100mg/m3 lower than the 2008 limit. GE is installing
separated over-fire air (SOFA) systems with triple-compartment over-fire
air nozzles installed on the furnace corners and side walls. The SOFA
systems were scheduled for service from 2005-2007.
