Utilisation of calorific value
- The flue gas temperature is a maximum of 15 K above the corresponding return temperature
- Calorific value used at a return temperature of about 55 °C and above
Motor
- industrial gas engine
- Model: MAG 49.4 S 311/HMG 434 S 113
- 4-cylinder Otto engine, water-cooled
- Displacement: 4.900 cm³
Coupling
Maintenance-free, plug-in, flexible metal/plastic coupling to compensate for radial, axial and angular misalignment
Generator
- vierpolige Synchronmaschine zum Parallelbetrieb am öffentlichen Netz
- Manufacturer: Weier GmbH
- Model: DGS-F-250L4 water-cooled
- 3 × 400 V, 50 Hz
- Anlaufstrom: 52 A (FU serienmäßig)
- Rated current: 72 A / 80 A
- cos φ: 1...0,9 (inductive/kapazitiv)
- Rated power: 62,5 kVA
- Rated speed: 1.500 min-1
Compensation
Due to the requirements in German code of practice VDE-AR-N 4105:2018-11, operating own generating systems without reactive power compensation is only permitted in exceptional cases. A cos φ of 0.95 is achieved with the standard fixed compensation.
