Finland-headed forest industry and energy technology provider Valmet Oyj has announced that it has been selected to supply a major boiler rebuild to E.ON’s Steven’s Croft biomass power station in Lockerbie, Scotland to secure trouble-free operation of the boiler for years to come.
Originally delivered by Valmet, the Steven’s Croft bubbling fluidized bed (BFB) boiler was started up in 2008. With good day-to-day maintenance and regular refurbishments, the boiler’s performance has been kept at an outstanding level.
For 16 years, E.ON Steven’s Croft has been providing a low-carbon power and heat solution to the local area, and central to this is the Valmet BFB boiler. The work carried out during the 2024 rebuild project emphatically positions the station to continue to safely deliver its operational objectives, in the most efficient and commercially-optimised way possible; whilst at all times, maintaining compliance with strict emission limit values, said Scott Robinson, Site Manager at Steven’s Croft power station.
Now, the boiler’s primary superheater, economizers, primary air preheater, and screen tubes will be renewed, securing its reliable operation for the future.
Valmet was selected to carry out this major work not only because of their OEM (Original Equipment Manufacturer) status but also because of 16 years of proven excellence in maintaining and optimizing our boiler. Our close relationship with Valmet has also facilitated a collaborative approach to developing a successful boiler maintenance strategy, underpinned by a long-term service agreement. I look forward to another successful project delivery from the Valmet team, Scott Robinson said.
Valmet’s delivery will include renewing several key components of the power station’s bubbling fluidized bed (BFB) boiler such as the primary superheater, economizers, primary air preheater, and screen tubes.
Special corrosion-resistant material will be used where applicable to prolong the lifetime of the parts. The delivery, the value of which has not been disclosed, is scheduled to take place during the second quarter of 2024.
We are happy to continue our good, long-standing cooperation with E.ON and Steven’s Croft power station with this delivery. We have developed a relationship that enables data sharing and open discussion, leading to numerous successful joint projects over the years – this one inevitably being the next in line, said Nigel Earp, Service Manager, EMEA Area at Valmet.
