Gas generators main characteristics

Whether standalone or gridparallel, the gas generator is the heart of your system.

  • max torque range
    the max torque range for gas generators normally is around 3,000 to 4,000 rpm. As this would limit the lifetime of an engine to about four or five years, gas generators run up to 1,500 rpm only. To improve torque within the operational range and at the same time the overall efficiency, an exhaust gas turbo charger is commonly used.
  • min operational range
    a standard gas generator can operate permanently between 50% and 100% of its capacity. Most Gas generators we work with operate between 30% and 100%
  • load curve characteristics
    gas generators can be promptly stressed only with about 10 - 15% of their max capacity. Too large jumps or drops in load cause the gas engine to stall.
  • electrical efficiency
    the electrical efficiency of gas generators working in the range between 50% and 100% of their max capacity ranges between 37 and 43%.
    1 m³ natural gas contains about 10 kWh of energy as well. Between 37 to 43% of this energy gets converted into electricity, the remaining energy leaves the system in form of heat.
    1 m³ gas generates about 4 kWh electricity, at 70 NRN / m³ this corresponds to a gas price of about 18 NRN / kWh without maintenance etc.
  • lifetime expectation
    German gas generators are designed to run 24/7 for much longer than just 10 years. Their maintenance concept “care before repair” provides a longlife reliable source of electricity. This concept incorporates standard actions like oil changes as well as constant telemonitoring via GMS from the German manufacturers for detecting upcoming problems. Routine replacements of even larger equipment and even the whole gas engine can be “booked” as well.
