Valmet to supply a complete steam boiler plant to Norske Skog Bruck in Austria

Finland-headed energy and forest industry technology major Valmet Oyj has announced that it will supply a complete steam boiler plant to Norske Skog ASA’s paper mill in Bruck an der Mur, Austria. With a fuel input of 56 MW, the new boiler will run mainly on refuse-derived fuels (RDF), pulper rejects, and sludge with natural gas as a secondary fuel.

Valmet will supply a complete steam boiler plant to Norske Skog’s paper mill in Bruck an der Mur, Austria. With a fuel input of 56 MW, the new boiler will run mainly on refuse-derived fuels (RDF), pulper rejects, and sludge with natural gas as a secondary fuel. It will partly replace the steam production of existing natural-gas-fired boilers as well as supply heat to the paper mill and local district heating network in Bruck, resulting in lower fossil carbon dioxide (CO2) emissions.

Norway-headed forest products major Norske Skog ASA acquired the Bruck paper mill in January 1996. Located in Bruck an der Mur in Styria, Austria, Norske Skog Bruck GmbH produces both light-weight coated (LWC) magazine paper and newsprint – about 275 000 and 128 000 tonnes per annum respectively.

Valmet’s turnkey delivery, valued at approximately EUR 40 million, includes Valmet’s BFB boiler plant that utilizes bubbling fluidized bed technology. It features a robust and integrated concept consisting of a gas-fired superheater for final steam superheating, baghouse filter for primary pollution control, SCR system for NOx reduction, combustion air humidifier as well as a condensing scrubber for heat production and final emission reduction.

Additionally, the delivery includes the construction of new buildings for the equipment, an upgrade of an existing Valmet DNA Automation System, and Valmet Industrial Internet (VII) solutions with DNA Combustion Manager and DNA Boiler Sootblowing Manager solutions and VII cloud services.

RDF and mill waste

The new boiler will run mainly on refuse-derived fuels (RDF), pulper rejects, and sludge with natural gas as a secondary fuel. It will partly replace the steam production of existing natural-gas-fired boilers as well as supply heat to the paper mill and local district heating network in Bruck, resulting in lower fossil carbon dioxide (CO2) emissions.

Norske Skog Bruck has chosen Valmet’s proven technology solution based on several well-performing reference plants. This project is the next step in our green diversification initiatives within the Norske Skog group and a milestone for further development of the Bruck site, said Enzo Zadra, Managing Director, Norske Skog Bruck GmbH.

The boiler plant will be handed over to the customer in 2022 and the investment will improve the mill’s cost competitiveness, reduce its carbon footprint and create a new business beyond publication paper by generating revenue from the combustion of RDF.

Valmet will deliver a technically demanding boiler plant in which all pieces of advanced technology are seamlessly integrated together to serve the mill’s targets. Valmet Industrial Internet (VII) solutions will play an important role in improving boiler performance and profitability, said Kai Janhunen, Vice President, Pulp and Energy business line, Energy business unit, Valmet.
