Valmet to supply flue gas plant to Helsinki bioenergy facility
Finnish firm Valmet Oyj will supply a flue gas condensing plant to Helen Ltd’s Vuosaari C bioenergy heating plant in Helsinki.
The new bioenergy heating plant will be very energy efficient, according to Valmet, as the heat from the flue gases will be recovered to increase district heat production by 69MW, using its advanced technology.
“Our company’s target is to be carbon neutral by 2035,” said Antti Saikkonen, project director at Helen. “As the flue gases after combustion are led to the condensing plant, it is possible to utilise the fuel to its fullest. The heat recovery at the Vuosaari plant will increase plant efficiency to about 122% based on the fuel’s effective heating value.”
Risto Hämäläinen, director of Environmental Systems, Pulp and Energy at Valmet, said: “The exceptionally high heat recovery is achieved by using absorption heat pumps to cool down the scrubber water and by cooling the flue gas going into the stack to below 12oC. The absorption heat pumps use low-pressure steam as the driving media instead of electricity.”
The flue gas plant will be provided to Helen in December 2022.
