Output limitations due to methane number
Notes:
The dew point shall be calculated for the specific
site conditions. The minimum charge air temperat-
ure shall be above the dew point, otherwise con-
densation will occur in the charge air cooler.
Compensating a low methane number gas by
lowering the receiver temperature below 45°C is
not allowed.
Compensating a higher charge air temperature
than 45°C by a high methane number gas is not
allowed.
The charge air temperature is approximately 5°C
higher than the charge air coolant temperature at
rated load.
The engine can be optimized for a lower methane
number but that will affect the performance.
