Wärtsilä’s BioPower products are based upon patented rotating BioGrate combustion technology, specially suitable for wet biomass such as wood residuals, wood chips, bark and sawdust.
The patented BioGrate technology used in Wärtsilä’s BioPower and BioEnergy plants ensures a highly efficient combustion process with many bio fuels, with flue gas emissions below the most stringent limits.
The BioGrate technology is especially designed for very wet fuels (up to 65 % moisture) and reliably burns most bio fuels with moisture content above 15 %.

Combined heat and power (CHP) plant increases energy independency and minimises emissions due to the high total efficiency, which may exceed 90%.
Electricity is produced in a steam Rankine cycle, which is optimized for generating electricity and thermal energy.
