Valmet to convert lignite-fired boiler into biomass boiler in Poland

Valmet has received an order to convert a lignite-fired boiler into a biomass-fired boiler at a power plant in Konin, Poland.

The order, worth approximately €20 million, came from Zespół Elektrowni Pątnów-Adamów-Konin SA (ZE PAK). The converted boiler plant will be delivered to the customer in autumn 2021.

The reconstruction of the K-7 boiler is the main element of Valmet’s project from fossil-based energy to renewable energy production. Valmet will convert the existing lignite-fired boiler into a biomass-fired boiler using bubbling fluidised bed technology. The firm will also supply a selective non-catalytic reduction solution to lower nitrogen oxide emissions and modernise the plant’s instrumentation and electrification systems.

Zygmunt Artwik, vice-president at ZE PAK, said: “Converting the existing boiler from coal into biomass combustion is a very cost-effective way for us to carry out this energy transition. The investment will enable Konin to be the first Polish city that is heated with energy originating exclusively from renewable sources.”

“This project represents the current need for renewable energy solutions in the energy markets at times when coal-fired plants are forced to shut down,” said Jouko Kylänpää, director of boiler rebuilds and conversions at Valmet’s pulp and energy business line.

“Existing coal-fired boilers can be modified to combust biomass and other renewable fuels, providing a better alternative to shutting a plant down.

“Additionally, conversion projects have a shorter project duration than building totally new plants.”
