Valmet to supply a boiler upgrade and a flue gas cleaning system to Stora Enso’s Anjala-Ingerois sites in Finland

Valmet will supply a boiler upgrade and a flue gas cleaning system to Stora Enso’s Anjala-Ingerois sites in Finland. The goal of the investment is to reduce the emissions and to ensure flexible use of different fuel mixtures in heat production, as well as to achieve better boiler performance and higher boiler efficiency.

The order is included in Valmet’s orders received of the second quarter 2021. The value of this kind of boiler rebuild is typically around EUR 15-20 million. The boiler outage is scheduled for the third quarter of 2022, but the installation work of the new baghouse filter will be done mainly before the shutdown. The project’s focus has been in finding ways to minimize the boiler shutdown time.

“We are looking for a new wider operation range with better operational performance, high reliability and compliance with future emission limits. We believe in Valmet´s capability to deliver the boiler upgrade which will meet our requirements,” says Ari Pöntinen, Manager, Investments and Operations Development, Anjala Mill, Stora Enso.

“The upgrade will significantly extend the boiler’s lifetime. Many of the modifications include new waste-to-energy features to make the existing boiler more suitable for using solid recovered fuel. At the same time, modifications and replacements will improve availability, secure safe operation and reduce maintenance costs,” says Jouni Koskinen, Senior Manager, Sales and Technology, Rebuilds and Conversions, Valmet.
