Valmet is supplying a complete steam boiler plant to Norske Skog’s paper mill in Bruck an der Mur, Austria.

Valmet’s €40 million turnkey delivery includes a BFB boiler plant that utilizes bubbling fluidized bed technology. It consists 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.

The delivery also includes the construction of new buildings for the equipment, an upgrade of an existing Valmet DNA Automation System and Valmet Industrial Internet solutions.

With a fuel power 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.

The investment will improve the mill’s cost competitiveness, reduce its carbon footprint and create new business beyond publication paper by generating revenue from the combustion of RDF.

The boiler plant will be handed over to the customer in 2022.
