Valmet plans boiler rebuild at E.ON’s Steven’s Croft power station

Valmet will deliver a major boiler rebuild to E.ON’s Steven’s Croft biomass power station in Lockerbie, Scotland, UK, to secure trouble-free operation of the boiler for years to come.

Steven’s Croft’s bubbling fluidized bed (BFB) boiler, originally delivered by Valmet, was started up in 2008. Now, the boiler’s primary superheater, economizers, primary air preheater and screen tubes will be renewed, securing its operation for the future.

Special corrosion resistant material will be used where applicable to prolong the lifetime of the parts.

Scott Robinson, site manager at Steven’s Croft power station commented, "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."

Robinson added, "Valmet were selected to carry out this major work not only because of their OEM (Original Equipment Manufacturer) status, but because of 16 years of proven excellence in maintaining and optimising 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."

Nigel Earp, service manager, EMEA Area at Valmet said, "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."

The value of the order has not been disclosed and the scheduled delivery period will be during the second quarter of 2024.
