Operation Manual / Power2 340-H / Low-pressure stage

6 Operation and service / 6.3 Expected replacement intervals

HZTL4053_EN

Rev.F

March 2022

Influencing parameters

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).
