Wärtsilä to build six biomass power plants in Germany
Finnish engineering company Wärtsilä has announced it received an order for six turnkey biomass-fuelled power plants in April. The total value of the order is approximately €100/US$135 million. The customer is the German-based company Bayernfonds BestEnergy GmbH & Co, which will utilize forestry residues to fuel the plants.
Construction is planned to start in July 2007, depending on the construction and operational permits being issued by the local authorities. It is anticipated that all six biomass power plants will have been completed towards the end of 2008.
Wärtsilä has so far installed more than 100 of its 'Biograte' burners in plants in the EU, Russia and Canada. The plants based on this technology have a set of properties [*.pdf] that make them one of the most successful products in the sector (diagram, click to enlarge):
BioGrate combustion results in a significantly lower levels of emissions compared to conventional grate technologies:
bioenergy :: biofuels :: energy :: sustainability :: climate change :: wood :: biomass :: co-generation :: combined heat-and-power ::
The wide grate area and the optimized grate construction ensure complete combustion with low unburned carbon content in the ash and low CO emissions in the flue gases. Precise division of combustion air in the grate enables very low NOX emissions. Even lower NOX emissions can be reached by applying SNCR technology to the system. Particle emission limits vary from country to country. Efficient and reliable electrostatic precipitators are used to remove dust from the flue gases.
All six plants to be build in Germany have an identical configuration based on the BioGrate, with an electrical power output of 5.6 MWe. The plants will burn wood residues from local forests, and the electricity that they generate will be fed to the main grid.
Bayernfonds BestEnergy GmbH & Co. KG is a unit trust company of Real I.S. AG, one of Germany’s biggest bank-related fund initiators and a wholly owned subsidiary of Bayerische Landesbank.
The commercial viability of the plants is supported by the German EEG law that was specifically created to promote investments in renewable energy.
“Wärtsilä Biomass-fuelled plants are clean and efficient. They are practical solutions for meeting need for renewable energy supplies with minimum environmental impact”, says Andreas Heibrock, member of the executive board of Real I.S. AG, enthusiastically. The plants 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%.
BioPower plants are highly modular, being based on well-proven standardised components with a reliable design approach. The plants can thus be delivered and installed quickly. Their proven technology results in a reliable, durable plant.
“With this product, Real I.S. demonstrates again in 2007 that it stands for innovative and trend-setting investment offers for private investors”, according to Andreas Heibrock.

- Optimised energy production for different needs: plants can be used for electricity generation only (condense plant) or for co-generation solutions designed for optimized heat recovery.
- High reliability through proven technology and extensive operational experience
- A patented rotating BioGrate combustion technology that has taken the universal grate technology into a new level of operational performance in terms of:
- Low emissions, on Nox and CO emissions it can be reached the strictest limits demanded at the market place
- High combustion efficiency with low unburned content in the ashes
- No supplementary firing required. The BioGrate is ignited and kept running purely with biofuels only up to 65% fuel moisture
- Modern automation allows unmanned operation with daily attendance.
- The standard plant design is based on modern architecture which allows the plant to be installed into urban surroundings. This combined with a low noise option makes it possible to locate the plant even next to a living area with housing close by.
