Metso supplies plant to Finland district heating project

By Staff | October 07, 2013

Metso has announced it will supply a 10 MW biomass plant for hot water district heating to energy company Elenia Lämpö in Turenki, Finland. The facility will be fired using locally sourced biomass, such as forest residues and peat and utilize Metso’s advanced BioGrate combustion technology, which enables a wide selection of fuels. The plant is scheduled to be operational in early 2014.


BioGrate is a rotating grate with a conical primary combustion chamber. The fuel input can range from 4 MW to 20 MW and is fed from underneath the center of the grate. Fuel dries in the middle of the grate by the heat radiating from the refractory lining bricks and by the flames without disturbing the burning fuel bed in the combustion zone. According to Metso, after the near complete combustion of the residual carbon, the ash falls from the edge of the grate to the ash space filled with quenching water.


“Elenia Lämpö's investment in the heating plant is an excellent example of a project that increases the utilization of local Finnish fuels in an energy-efficient and environmentally friendly manner. The Turenki site highlights the need for a flexible and highly adjustable plant solution that is able to effectively respond to heating needs throughout the year. The advanced BioGrate combustion technology enables a wide selection of fuels, low internal consumption and highly flexible adjustability,” says Teemu Koskela, who is in charge of bioheat plant sales at Metso.
