Valmet supports Hamburger Containerboard Dunaújvaros in Hungary in long-term plant development with two deliveries
Valmet Oyj trade press release, May 28, 2025, at 1:00 p.m. EEST
Valmet will deliver an additive feeding system upgrade and a redundant steam reduction station system to Hamburger Containerboard Dunaújvaros in Hungary. Together, the deliveries will support the customer in their long-term plant development targets by improving the power boiler availability and environmental performance, as well as enabling participation in the growing electricity reserve market, respectively.
The order for the additive feeding system upgrade was included in Valmet's orders received of the first quarter 2025. The order for the steam reduction station system is included in Valmet’s orders received of the second quarter 2025. The value of the orders will not be disclosed. The installations are scheduled to take place during the mill’s annual shutdown in autumn 2025.
“We are happy that our cooperation with Valmet leads to great initiatives such as these two projects. Together, we will push our performance forward by enabling better boiler availability and production flexibility, as well as increasing our business opportunities in the growing electricity reserve market,” says Dániel Panyi, Project Manager at Hamburger Containerboard Dunaújvaros.
“We have successfully worked with the Dunaújvaros mill since the delivery and start-up of the Valmet CFB Boiler in 2015. Our long-term service agreement paves the road for joint development projects, and we are proud to continue the shared journey with the customer,” says Sampo Smolander, Sales Manager, Energy Services, EMEA, Valmet.
Delivery’s technical information
The delivery will include an additive feeding system upgrade with a new calcium hydroxide silo and a redundant steam reduction station system for turbine bypass.
The upgrade will improve the acid gas removal from the boiler’s flue gases. In the future, the two redundant lines will provide non-stop service and better environmental performance. In addition, a new 100 m3 silo will be delivered to increase the storage capacity for calcium hydroxide.
As for the other delivery, the customer wants to participate in the automatic Frequency Restoration Reserve (aFRR), a process for restoring the frequency and power balance in the power grid. To do so, they must be able to offer a down capacity to the electricity network while keeping the necessary boiler load for their cardboard production. Thus, they will need to install a high-pressure steam reduction station to handle the excessive steam flow.
Both deliveries include engineering and manufacturing new equipment with necessary piping and valves, project management and site supervision, plant automation system changes, installation work, and commissioning.
