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, a city approximately 37 miles (60 km) from Brussels in Belgium. The Langerbrugge Mill produces newsprint and uncoated magazine paper entirely from recovered paper.
Startup for the plant is scheduled for the third quarter of 2010. The value of these types of boilers ranges from $78 million to $140 million (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. In Metso's circulating fluidized bed (CFB) technology, the bed material flows together with flue gas through the furnace, after which it is separated from gas by cyclones and returned to lower part of the furnace. CFB technology is suited for higher heating value fuels such as coal, drier biomass, recycled fuels and mixtures of the same.
The boiler will burn a wide range of fuels including refuse-derived fuel (RDF) and packaging-derived fuel (PDF), recycled wood and deinking sludge, as well as coal as backup fuel. The multifuel boiler technology will enable the customer to generate power with the most competitive fuel mix possible. The delivery also will include a flue-gas cleaning system.
The new combined heat and power plant will increase paper mill's self-sufficiency in electricity and satisfy the needs 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.
An integrated paper, packaging and forest products company, Stora Enso produces newsprint, magazine paper, fine paper, consumer board, industrial packaging and wood products.
