Elenia Lämpö Oy’s Vanaja power plant in Hämeenlinna, Finland, will use a biomass-fired boiler to raise the share of renewable fuels used in the city’s district heat production to over 80 percent and increase the energy efficiency of its heat production. 

Valmet will deliver a 35 MWth biomass-fired boiler plant that utilizes bubbling fluidized bed (BFB) technology. The company will also supply an electrostatic precipitator and a flue gas condenser that increases heat capacity by 10 MW. Assembly work on the new boiler plant will start in the fall of 2019 with startup scheduled for 2020. 

The boiler plant will mainly run on wood-based fuels, such as forest residues and sawdust and bark originating from side streams of the woodworking industry.
