- patented rotating BioGrate product- bio fuel expertise

Energy from bio mass

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 %.

Wärtsilä BioPower Products

BioGrateTM Combustion Technology: Rotating conical grate Several ( 4 - 10 ) combustion zones Zone controlled primary air inlet

under the grate for complete combustion Fuel feeding from centre bottom which

don’t disturb combustion process Under grate wet ash removal Designed for wet fuels up to 65%-w

Long lifetime Reliable operation High efficiency combustion Low emissions

Wärtsilä Biopower

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.
