NATURAL GAS CHP POWER PLANTS
Series "Piemonte"
Natural gas CHP Power Plants
Natural gas CHP power plants with use of high electrical efficient reciprocating engines (Otto cycle) combined with recovery boilers. High reliability Power Plant model suitable for district heating plants with electrical power higher than 4 MWel. Can be further enhanced upon request through integrated fresh-air module and/or integration boilers up to a maximum thermal power of 10 times that of electric power. For a good profitability, district heating shall not cost more than € 800,000 for each nominal MWt installed with 40% more selling thermal energy than that deliverable.
- Electric Power 0,25 to 10 MWel.
- Thermal power: 0.25 to 100 MWt.
- Cycle: CHP Otto simple or combined.
- Fuel: natural gas.
- Feasibility study reference: PIEM1, PIEM2.
- Max electric efficiency: 45%
- Max overall efficiency: > 85%.
- Certification: CE / PED as a whole.
