Actuators help NOx reduction at UK power
station
Rotork Jordan electric linear actuators have been selected for the operation of specialised dampers for an environmental upgrade project at the EdF West Burton power station at Retford in Yorkshire
Rotork Jordan actuators facilitate environmental upgrade at UK power station Rotork Jordan electric linear actuators have been selected for the operation of specialised dampers at the centre of an environmental upgrade project at the EdF West Burton power station at Retford in Yorkshire West Burton is already equipped with a flue gas desulphurisation (FGD) plant that removes 90% of sulphur dioxide (SO2) emissions from boiler gases in accordance with forthcoming legislation, and is now reducing its oxides of nitrogen (NOx) emissions ahead of the EU Large Combustion Plant Directive (LCPD) that comes into force in 2008

Emission reduction programme uses Jordan actuators
Rotork Jordan electric modulating valve actuators have been introduced at the 4000MW Drax Power Station during the latest part of the station's environmental upgrade programme
This is achieved by installing Separated Over Fire Air (SOFA) systems, involving specially designed injectors, ducting and dampers on the generating plant.
The contract has been recently awarded to GEEER of Ohio, USA, and the work is now proceeding on the first of the station's four units.
Jordan LA2000 range electric linear actuators have been selected for the automation of the dampers on this particularly harsh duty.
The actuators are controlled by a 4-20 mA signal, fed to the Jordan digital amplifier, which can be remotely mounted to enable the actuator to operate in the plant ambient temperatures up to 108C (225F).
This capability, combined with a modulating duty rating of 600 starts/hour and precise positioning, makes the LA2000 an ideal, low maintenance solution for many power station applications.
Jordan actuators were recommended by Rotork subsidiary Exeeco, who worked closely with GEEER on the project.
Sales Director Ian Elliott enthuses: "This is a major move forward for West Burton as the existing hydraulic actuators have caused problems during operation and incurred large maintenance costs during plant outage shutdowns.
The introduction of Rotork Jordan actuators will remove this expensive and unpredictable maintenance cost as well as improving the operation of the Secondary Air Damper Control, which is critical for successful emissions reduction.".
