ANDRITZ to supply biomass boiler island to Karlstads Energi, Sweden
International technology Group ANDRITZ has received an order from the municipal energy company Karlstads Energi AB, Sweden, for the supply of a new biomass-fueled boiler for the Combined Heat and Power (CHP) plant at Hedenverket. Start-up is scheduled for the end of 2014.
The scope of delivery includes the complete boiler island (fuel bin to flue gas fan outlet), based on ANDRITZ’s well-proven Bubbling Fluidized Bed (BFB) design and combining high efficiency with excellent environmental performance. The boiler will burn wood-based fuels (logging waste, sawmill chips, and bark), which are widely available in the region, to generate steam at the rate of 127 t/h, equal to 88 MW of thermal power.
According to Karlstads Energi, construction of the new CHP facility will allow the municipality to phase out all energy production using fossil fuels and increase production of electricity from renewable resources. “The completion of this plant will enable us to secure a long-term electricity and district heating supply with sustainable and renewable fuels using highly efficient and environmentally friendly technology,” says Mats Preger, CEO of Karlstads Energi.
