Wärtsilä Corporation was awarded a contract by Less & Timber, Czech Republic in November 2007 to supply a biomass-fuelled combined heat and power plant for the company’s sawmill in Čáslav, around 100 km east of Prague. This is the first biomass power plant Wärtsilä will deliver to Czech Republic.
The new plant will burn residue in the form of bark and wood chips from the sawmill and have a net electrical power output of 4.3 MWe, and a thermal output of up to 10 MWth. The electricity will be sold to the national grid and the heat will be used for drying in the sawmill. The electrical output in condensing operation is 5.5 MWe.
Wärtsilä will deliver a complete BioPower 5CEX plant under an equipment procurement contract without civil works and foundation works. It is due to be handed over in October 2009.
Wärtsilä’s good reputation and references were the main reasons Less & Timber chose a BioPower plant.
Wärtsilä’s biomass-fuelled plants are clean and efficient. They are practical solutions for meeting needs 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 55%. The SOx emissions of such wood-fuelled plants are negligible. The fly ash is removed from the flue gases in an electrostatic filter.
The BioPower plant operates on a closed steam-feed water cycle separate from the hot water system. Superheated steam is generated in an efficient water-tube boiler, and supplied to a high-efficiency reaction-type condensing extraction steam turbine driving an alternator. The water is heated by steam extracted from the turbine.
BioPower 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.

LESS in brief
LESS provides complex services to forest owners. It was founded in 1992. Since then, the Less trademark had acquired a strong position on the market and a good reputation among its customers. Thanks to this, the company keeps growing and provides always widening spectrum of services.
In the short-term future LESS holding will stand on three equivalent pillars:
-forestry (including transport of logs)
-timber processing - sawmills (including glued solid wooden materials)
-bioenergy (combined heat and electric power production from biomass)
