Valmet to Build Flue Gas Condensing Plant for Helen in Helsinki

September 03, 2026 – Espoo, Finland -- Valmet will deliver a flue gas condensing plant to Helen's Salmisaari K6 pellet heating plant in Helsinki, enabling the energy company to recover additional heat from flue gases and boost district heating output without increasing biomass fuel consumption.

Order was booked in Valmet's second-quarter 2026 intake, with startup set for second half of 2027

The contract, whose value was not disclosed, was included in Valmet's orders received for Q2 2026. The flue gas condensing plant is scheduled to start operations during the second half of 2027, completing the Salmisaari K6 and K7 heating plant complex previously supplied by Valmet.

Helen targets more heat output from existing biomass fuel volumes

The system recovers heat previously lost in flue gases, converting water vapor from combustion into usable thermal energy that is fed back into Helsinki's district heating network. This raises district heat output without increasing pellet consumption, supporting Helen's goal of maximizing renewable energy yield and cutting emissions in its heat production. Helen aims for net-zero emissions by 2040.
