Valmet to supply wood pellet heating plant to Finnish power facility

Finnish technology firm Valmet will supply a wood pellet heating plant to electricity firm Helen Oy's Salmisaari power plant.

The wood pellet plant will enable Helen to increase the use of bio fuels in district heat production in Helsinki. The new plant helps the city of Helsinki to meet its aim of increasing its production of renewable energy.

The start-up of the heating plant is expected to take place at the beginning of 2018.

The order is included in Valmet's second-quarter orders received in 2016. The value of the order is more than €20 million.

"Utilisation of wood pellets as fuel increases the use of domestic renewable fuels in energy production and creates jobs in raw material sourcing and transport. The heating plant also supports Helen's goals of climate-neutral production," said Heikki Hapuli, director of Production and Distribution at Helen Oy.

"In designing the Salmisaari wood pellet plant we have been able to utilise the experiences gained in earlier, similar projects,” added  Kai Mäenpää, vice president, Energy Sales and Services Operations, Valmet.

He explained: “The plant fulfils the tightening environmental requirements by utilizing a low-NOx burner technique and efficient dust removal.

"Pellets made of barkless raw material as well as industrial pellets, which have been produced by also including bark and forest residue, can be utilized as fuel at the plant.”
