DISTRICT HEATING STEAM BLEEDING POWER PLANTS
Series "Lazio"
Steam bleeding Power Plants
Electric and Thermal Production or CHP (virgin wood chips) Power Plants. In case of cogeneration or electricity generation only, a vector fluid (diathermic oil) heating is provided in order to indirectly generate organic fluid steam with turbomachinery (Rankine cycle, ORC) expansion. Generation of thermal energy in cogeneration process can not be adjusted independently from electricity generation. Possible integration of thermal energy can be accomplished by biomass boilers or traditional fuel.
Power Plant model suitable for district heating plants with electrical power lower than 2 MWel. Same as for ""Brianza"" series, electrical energy generated by this plant type is patronized through "green certificates" for higher than 1 MWel powers and by all-inclusive tarif for powers under 1 MWel. District heating is almost always required for authorize reasons and for a good profitability it shall not cost more than € 800.000,00 for each nominal MWt installed.
- Electric Power: 0.2 to 2 MWel
- Thermal power: 0.5 to 20 MWt
- Cycle: CHP Organic Rankine
- Fuel: virgin woodchips
- Feasibility study reference: TN1, TN3
- Max electric efficiency: 18%
- Max overall efficiency: 85%
- Certification: CE / PED as a wholeasd
