2.2.3 Operation conditions CHP
The following operating conditions are required to
maintain the warranty:
• Ensure dust and halogen-free cooling and
combustion air
• Ensure that the exhaust air and exhaust gas lines are
correctly dimensioned, and run them separately
• Maximum setup height without a drop in
performance: depending on model used 100 ... 500
meters above zero
• Ratio of starting/operating hours: 1 start to 6
operating hours averaged over the year
• Methane count: 80
• Natural gas Hi = 10 kWh/m
3
• Maximum exhaust gas counterpressure depending on
GenSet motor manufacturer 40 ... 60 mbar
• Module only suitable for setup within a building
• The condensate and flue gas line are pressurized and
must be appropriately designed, and the operating
pressure must be demonstrated in a pressure test.
