The specified values are guideline values and not guaranteed values; see Influencing para-
meters.
Influencing parameters
The specified values are guideline values and are not guaranteed. The actual values can devi-
ate significantly from the guideline values, for example, due to the following influences:
¡ Fuel quality and fuel treatment
¡ Load profile (thermal cycling, also number of starts/stops, emergency shutdowns, oper-
ating point)
¡ Gas inlet temperature
¡ Turbocharger specification
¡ System-specific operating conditions (combustion quality, exhaust gas composition)
For bearing parts
¡ Lubricating oil quality (oil filtering, oil condition, oil monitoring)
¡ Load profile (speed, pressure conditions, temperature)
¡ Number of starts/stops
¡ Unbalance of the rotor (degree of contamination).
