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).
