A Russian power plant will become the first in the country and only the second in the world to use an advanced supercritical circulating fluidised bed (CFB) boiler.

PJSC EnergoMashinostroitelny Alliance (EM Alliance) has placed an order with Finland-based Foster Wheeler Energia Oy for the boiler, which will be installed in Novocherkassk, Russia. The 330 MWe unit will be located at the Novocherkasskaya GRES facility, which is owned by The Sixth Wholesale Power Market Generating Company (WGC-6).

The boiler is the first CFB to be built in Russia and the second CFB ordered in the world that utilises advanced supercritical once-through (OTU) steam technology. The first such CFB is located in Poland, where Foster Wheeler is currently building a 460 MWe OTU-CFB that is planned to come on-line in the first quarter of 2009.

OTU-CFB technology improves overall power plant efficiency, resulting in producing about 5-10 per cent more electricity from the same amount of fuel consumed as compared to a conventional subcritical steam power plant.

Foster Wheeler will supply the steam generator, auxiliary equipment and advisory services for erection and commissioning of the boiler island. The boiler will be designed to burn both anthracite and bituminous coal along with a potential of 30 per cent anthracite slurry.
