Alstom to supply clean-coal technology to RWE

Gerald Ondrey

Alstom (Paris, France; has won a contract to supply the boilers for two 800-MW units at the existing coal-fired Westfalen Power Station, located in the North-Western part of Germany near the town of Hamm and operated by RWE Power AG. The two new bituminous-coal-fired units will be  among  the cleanest and most efficient in the world.

Under the terms of the contract, the value of which is approximately 500 million euros, Alstom will supply the complete boiler islands and auxiliary equipment, including erection and commissioning. When completed in 2011, the new units will achieve cycle efficiencies of about 46%, substantially more than the European average of 36% efficiency for existing bituminous coal-fired plants.

The new Westfalen supercritical boilers with steam temperatures of 600°C will reduce all emissions, including carbon dioxide (CO2), by about one-third compared to the fleet of older units. Thanks to the application of Alstom’s advanced technical solutions, the levels of oxides of nitrogen (NOx) and sulphur dioxide (SO2) emissions will be reduced very significantly. In addition to superior environmental performance, Alstom’s high-efficiency supercritical technology provides lower fuel costs, operating flexibility and high unit availability.

“At Hamm we are erecting one of the most advanced bituminous coal-fired twin unit plants worldwide that-compared with old units- helps save some 2.5 million tons of CO2 annually while generating the same power," says Johannes Lambertz, CEO of RWE Power AG.
