Rotork electric valve actuators are being used in a refurbishmentproject that will see a coal-fired power station re-open withincreased capacity, improved efficiency and the latest cleanenvironmental technology.
Uskmouth B power station, at Newport inSouth Wales, was built in 1959 and closed in 1995.
In 1998 thestation was purchased by the global power company AES, who haveappointed a consortium led by General Electric International Incand including ABB Combustion Services Ltd and ABB EnvironmentalSystems to perform a complete refurbishment and re- commissioningproject.
When the station reopens later this year - renamed asAES Fifoots Point - its generating capacity will increase from360 to 393 megawatts whilst a new flue gas desulphurisation plantand low-nox burners together with low profile fan assistedcooling towers will ensure an efficient environmentalperformance.
Most of the Rotork actuators are being supplied fornew low-nox burners and dampers that are being installed,together with refurbished boilers and new economiser elements, byABB Combustion Services Ltd.
A total of 144 Rotork IQ, AQ and Qrange actuators have been fitted and commissioned for multi-turnand quarter turn valve and damper operation.
Peter Woolley, ABBCombustion Services Ltd Project Manager for the Fifoots Project,explained; "The main reason for selecting Rotork to supplythese actuators was their ability to meet the full range ofapplications from a single source, together with provencapabilities on other projects." All the Rotork actuatorswill be controlled by a new ABB Automation distributed controlsystem (DCS) which will supervise the operation of there-commissioned station.
The actuators are designed to provide adirect interface with the DCS and communicate vital valvereal-time positional and status information to the station'sthree control rooms, confirming that the plant is operatingefficiently.
