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

Wärtsilä Biopower Wärtsilä - Bio. Grate. TM Combustion Technology: n Rotating conical grate n Several ( 4 - 10 ) combustion zones n Zone controlled primary air inlet under the grate for complete combustion n Fuel feeding from centre bottom which don’t disturb combustion process n Under grate wet ash removal n Designed for wet fuels up to 65%-w ì ì Long lifetime Reliable operation High efficiency combustion Low emissions TM

Wärtsilä Biopower Today’s Products Bio. Grate - Combustion technology: n Patented combustion system Bio. Energy Thermal Plants: n Hot water or / and low pressure steam n Bio. Energy Thermal 3 and 5 MWth Compact n Bio. Energy Thermal 7, 10, 12, 15, 20 MWth Bio. Power Plants: n Bio. Power CHP 2 and 5 n Bio. Power Condense 2 and 5

Bio. Power CHP Plant n n 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. Steam Turbines Generator Condenser Fuel District Heating Bio.
