Metso Power, a part of Metso Paper business area, will supply Stora Enso with a power boiler to company's new combined heat and power plant at Langerbrugge Mill in Gent, ca 60 kilometers from Brussels in Belgium. Start-up for the plant is scheduled for the third quarter of 2010. The value of these types of boilers ranges from EUR 50 to EUR 90 million, depending on the scope of the delivery. The power boiler with 125 MW steam capacity will be a multi-fuel boiler using circulating fluidized bed technology. The boiler technology will enable the customer to generate power with a competitive fuel mix since the boiler will burn an exceptionally wide range of different fuels including refuse derived fuel (RDF) and packaging derived fuel (PDF), recycled wood and de-inking sludge, as well as coal as back-up fuel. The delivery will also include a flue gas cleaning system. The new combined heat and power plant will increase paper mill's self-sufficiency in electricity and totally cover the need of process steam. Fuel costs will be significantly reduced while increasing the use of recovered fuels and biomass. With this investment the energy production will be efficient and environmentally friendly, enabling Stora Enso to further reduce its carbon dioxide emissions.
