Biofuel boiler
10 Jun 2005
Aker Kvaerner has won a contract to supply a biofuel-fired boiler plant for paper and board plant in Sweden, and has also won several contracts for biofuel boiler modernisations in Sweden, Lithuania and Slovakia.
The contracts are worth a total of 65million Euros.
The boiler plant is to be installed at Kappa Kraftliner’s plant in Piteå, Northern Sweden, where it will be used to boost the plant’s electricity production. The boiler has a capacity of 132MWth, and is based around a bubbling fluidised bed fuelled by bark, sawdust, forest residue, peat and sludges, along with recycled fibre dust and wood waste.
The system also includes a flue gas cleaning system. The plant is scheduled for start-up in spring 2007.
Also in Sweden, AK is to rebuild a boiler for Ängelholm Energi’s plant in Åkerslund, Southwest Sweden. This will increase the plant’s thermal capacity by 50%, and will allow it to burn a greater range of fuels, including demolition wood, peat, forest residue and recovered wood.
In Lithuania, the company is to modernise an old power boiler to produce green electricity, installing bubbling fluidised bed technology; while in Slovakia, a similar project will allow Mondi Business Paper to use bark as fuel.
