The actual values can deviate considerably 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)
Gas inlet temperature
Frequency and execution of turbine and compressor cleaning
Specification of the low-pressure stage
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).
