Doosan awarded major biomass conversion project

E.ON has awarded Doosan Power Systems a contract to upgrade its coal-fired power plant in Provence, France, converting it into a biomass-fuelled power plant.

Located in Gardanne ” Meyreuil, the project will help to create France’s largest biomass-fired power plant to date as part of the E.ON Group’s “cleaner, higher performance energy” strategy.

The new biomass unit, generating electricity from the combustion of wood – including forest chips, green residues and recovered wood – will be converted from the existing coal-fired Provence 4 unit.

It will provide 150 MW of power with base production of more than 7500 hours per year until 2034, which corresponds to the annual electrical consumption (except for heating) of 440,000 households. This investment will reduce the CO2 balance by 600,000 tons per year.à‚  It will also extend the life of the Provence power plant for a further 20 years, while helping structure and develop the region’s wood-energy industry.

Work will begin this summer with the first firing in the autumn of 2014 and startup of operations in early 2015.

Doosan Power Systems will be responsible for converting the existing Provence facility to biomass, in particular the 20-year-old coal-fired CFB (circulating fluidized bed) boiler and renovating the steam turbine.

The project will be led by the Germany-based CFB specialist, Doosan Lentjes, who supplied the original CFB technology and key components for the plant in 1992.

At the same time, the company’s turbine specialist, Doosan Skoda Power, will replace the inner steam path of the existing steam turbine to match the new output and enhance plant efficiency, and the life-time extension works on the remaining equipment will be undertaken by Doosan Babcock.

The assembly of the new equipment will be subcontracted locally to ADF, a French group located in the Fos-Berre basin that specialises in the maintenance of power generation sites.
