Foster Wheeler wins Swedish biomass retrofit contract

17 May 2005 – Foster Wheeler Ltd said Monday that its Swedish power group subsidiary has been awarded a contract to supply a biomass-fired bubbling fluidized bed (BFB) retrofit to Stora Enso Hylte AB. The retrofitted boiler produces steam and electricity for the Hylte pulp and paper mill in Hyltebruk in southern Sweden.

The total investment cost of the project is approximately $51m (€40m). The Foster Wheeler contract value was not disclosed. The project will be included in the company’s second-quarter 2005 bookings.

“Foster Wheeler is delighted to be awarded this contract by Stora Enso Hylte AB. Our partnership goes back many years. Foster Wheeler supplied a 49 MWth CFB boiler to the Hylte mill in 1982, and it is still in daily operation,” said Bernard H. Cherry, president and chief executive officer, Foster Wheeler Global Power Group. “The project concept, including several special technical solutions, was actively developed by Foster Wheeler and Hylte experts, resulting in this project.”

The contract includes a BFB boiler retrofit to the existing Axon-oven/natural gas-fired boiler (90 t/h, 63 bar, 450 degrees C, 69 MWth), internal fuel feeding, necessary new auxiliary equipment, electrical motors and field instruments, erection and commissioning. The primary goals for the retrofit are to enable firing of sludges in addition to drier biomass, control of fouling and corrosion and control of emissions. The main fuels for the boiler will be de-inking sludge, biosludge, demolition wood and bark. Work on the project will start immediately, and the plant is scheduled for handing over to the customer in May 2006.

Stora Enso is an integrated paper, packaging and forest products company producing publication and fine papers, packaging boards and wood products. The company serves its mainly business-to-business customers in Europe, North America and Asia.
