Influencing parameters
The specified values are only guide values and not guaranteed. The actu-
al values can deviate considerably from the guide values due, for exam-
ple, to the following influences:
 Fuel quality and preparation
 Load profile (thermal load cycles, also starts / stops, emergency shut-
downs)
 Gas inlet temperature
 Frequency and execution of turbine and compressor cleaning
 Turbocharger specification
 System-specific operating conditions (operating point, combustion
quality, composition of exhaust gas)
For bearing parts
 Lubricating oil quality (oil filtration, condition of lubricating oil, oil moni-
toring)
 Load profile (rpm / speed, pressure conditions, temperature)
 State of rotor unbalance (degree of contamination)
