Wärtsilä wood-fired heating plants for Stora Enso in Russia

Wärtsilä Corporation, Trade press release, 27 December 2006 at 13:00 UTC+2

Wärtsilä Corporation has won an order to deliver two BioEnergy wood-fired heating plants to the Finnish/Swedish paper company Stora Enso for installation in Russia. Their combined heating capacity is 24 MWth.

One plant will be at Impilahti in the Russian region of Karelia. It will be equipped with a Wärtsilä BioEnergy 10 boiler unit.

The other plant will be at Nebolch in the Novgorod region of Russia. It will be equipped with two Wärtsilä BioEnergy boiler units in the same building. One will produce 6 MWth and the other 8 MWth. Thus the plant will have the flexibility to operate on one BioEnergy boiler unit if the heat demand is low and both boiler units when the heat demand merits. The provision of two boiler units also ensures continuity of heat supply when one or the other is being serviced. The Impilahti plant will start producing heat at the end of September and the Nebolch plant in October 2007.

Both plants will burn wood residue in the form of bark from the Stora Enso sawmills. They will provide heating in the form of hot water for the sawmills’ needs. Apart from the economical benefits of burning residue material, the plants will have the ecological benefit of using a renewable resource thereby being neutral with respect to carbon emissions and thus global warming.

“An important factor in choosing Wärtsilä as our supplier, was Wärtsilä’s long experience of boiler plant deliveries to Russia. Wärtsilä’s BioEnergy plants have the proper certificates and licenses for the Russian market, and we have very good experience from previous cooperation with Wärtsilä as a business partner,” says Tapio Särkkä, Project Manager, Stora Enso Timber Oy Ltd.

There are already seven Wärtsilä BioEnergy boiler plants with a combined heating capacity of 52 MWth owned by Stora Enso in Estonia, Latvia and Lithuania.

Wärtsilä's biomass-fuelled plants are clean and efficient. They are practical solutions for meeting the need for renewable energy supplies with minimum environmental impact. They incorporate patented Wärtsilä BioGrate combustion technology to burn biomass fuels with high combustion efficiency and low NOx and CO emissions. The moisture content of the fuel can be as high as 65%. The NOx emissions of such wood-fuelled plants are negligible. The fly ash is removed from the flue gases in an electrostatic filter or multicyclone in accordance with local regulations.

Wärtsilä BioEnergy plants are highly modular, being based on well-proven standardised components with a conservative design approach. The plants can thus be delivered and installed quickly. Their proven technology results in a reliable, durable plant. They are also highly automated, enabling unmanned operation.
