District heating in Braås
The plant in Braås has been completely fossil fuel free since 2012, when we replaced the Eo1 oil with biodiesel (RME). This means that all of the fuel used at Braås is renewable.
About 150 customers get their heat from the plant, with the largest customers being Volvo Articulated Haulers and Vidingehem. The network encompasses 9,881 metres of piping with a total volume of 205 cubic metres.
The plant was commissioned in 1999 and was fitted with a JF Integral boiler with an output of 3.5 MW for wood fuel together with two VEÅ oil-fired boilers with outputs of 3 MW and 6 MW, respectively, for peak loads and backup purposes. In 2001, the plant was supplemented with a JF pellet-fired boiler with an output of 1.5 MW. Multi-cyclones are used to treat the flue gases from the biofuel-fired boilers.
The plant produces about 20 GWh/year, replacing about 2,200 cubic metres of heating oil with biofuel. The raw material for the 3.5 MW boiler is comprised of 100% renewable biofuel from the forest, such as branches, treetops and other residues from the forests of Småland. The 1.5 MW boiler is fired with wood pellets.
