Valmet to Build Flue Gas Condensing Plant for Helen in Helsinki
Espoo, Finland – September 03, 2026 -- Valmet will supply a flue gas condensing plant to Helen's Salmisaari K6 pellet heating plant in Helsinki, an order booked in Valmet's second-quarter 2026 order intake with commercial start-up scheduled for the second half of 2027.
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.
