Alstom has won an order worth around €7m to supply German Utility E.ON Kraftwerke GmbH with two 20 MW biomass power plants.
The plants will be built at Landesbergen in Lower Saxony and Zolling in Bavaria and will use mainly waste wood as fuel. Each plant will have a net power output of 20 MWe and a net plant efficiency of more than 30 per cent in condensing operation mode. The two plants are scheduled for commissioning in December 2003.
Alstom will supply the two plants on a turnkey basis, including key components such as the steam turbine, cooling system, boiler and firing system, flue gas cleaning system and fuel and ash handling systems. It will be responsible for overall engineering, site preparation and civil works in addition to erection and commissioning of all mechanical, electrical and control systems.
Alstom say the plant design minimises emissions whilst optimising the boiler, steam turbine and water-steam cycle to maximise efficiency. The boilers will be equipped with Selective Non-Catalytic Reduction (SNCR) technology as well as Alstom’s state-of-the-art Flue Gas Cleaning system, comprising a Novel Integrated Desulphurisation (NID) system and bag house filter. The firing system is based on the well proven and referenced Alstomtravelling grate.
All equipment supplied will be fully compliant with Germany’s stringent environmental protection and renewable energy laws.
Alstom has recently supplied equipment for biomass projects in Australia (wood and bagasse) and Spain (olive-oil residue). In Germany, the company also recently carried out conversion work at the Rosenthal power plant to allow an existing boiler to burn wood residues.
