Consumption
Primary Energy : Heavy Fuel Oil => Natural Gas
Energy Conversion : Wärtsilä NSD´s engine-generating-sets ranging 0-17 MW
Energy Distribution : Basic heat recovery => Hot Water and / or Steam
Steam can be used for additional electricity production in a
“Combined Cycle” using a steam turbine generator.
Energy Consumption : Based upon electricity and heat, where the heat part can be
utilized in a number of different ways, i.e. as ; hot water,
steam, cold water and fresh water.
Cogeneration and Cogeneration Applications
1) Heat Recovery - Hot water production
- Steam production
- Hot water and steam production
2) Cogeneration Applications - Cold water production by absorption chillers
- Fresh water production by sea water desalinators
3) Combined Cycles - Diesel Combined Cycles (DCC)
- Feedwater Combined Cycles (FwCC)

recovered is mainly depending on the sulphur content
of the fuel used.
LO and Cooling Water Heat % of the fuel input can be recovered as hot water.
The amount of hot water generated is mainly limited by the
heat recovery water flow and return temperature. The
maximum temperature which is possible to recover is

11. Wärtsilä BioPower Products
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 %.

12. Wärtsilä - BioGrateTM Wärtsilä Biopower
BioGrateTM Combustion Technology:
Rotating conical grate
Several ( ) 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

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

14. BioPower CHP Plant
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.

The standard steel structure building of the BioPower and BioEnergy plant is very
fast to construct and meets normal western noise requirements inside and outside.
Fire protection is according to local norms. A high level of automation enables
unmanned operation.
The plants are delivered in large modules, and due to the high degree of
prefabrication, the delivery time is short.
Wärtsilä can deliver plant equipment with supervision of installation,
a functioning plant process or a complete turn-key installation, depending on
customer needs.
