Case Study: Didcot Power Station
Summary: Magnom™ Process Units installed onto the lubrication circuits of all coal pulverising mill open gear transmissions (32 off total – 8 per generator, 4 generators)
Customer: Innogy Plc
Didcot A Power Station
Oxon
Application(s): Transmissions [Large Scale] Lubrication Oils
Industry(s): Power Generation
Notes
The Magnom™ technology has been trialled and installed into Didcot A, the 2040 MW coal fired power station first commissioned in 1972, as a protection device for the open gear transmissions in the vertical axis coal mills.
The Magnom units have dramatically reduced the amount of contaminant in the ExxonMobil lubricant. The Magnom was the only device capable of achieving this without incurring a prohibitive pressure drop.
The Innogy engineers and ExxonMobil have a continual responsibility to review operating practice with a view to improving efficiency, extending asset life and, importantly, to achieve and where possible exceed increasingly stringent environmental targets. The Magnom™ installation has met all of these ends.
Customer comments
“Magnom is a no brainer in this type of application and can be rolled out into all vertical axis mills which are common to most coal fired power stations.”
