Stopping The Engine - ABB PT004165 Operation Manual

Operation Manual / Power2 850-M / High-pressure stage
6 Operation and service / 6.4 Stopping the engine
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 high-pressure stage
¡
System-specific operating conditions (combustion quality, exhaust gas composition)
¡
Atmospheric humidity after the intercooler.
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).
6.4

Stopping the engine

CAUTION
Residual heat in the low-pressure and high-pressure stage
If the residual heat in the low-pressure and high-pressure stage is not suffi-
ciently dissipated by the circulating lubricating oil, machine damage could
occur.
Observe the post-lubrication times and the oil pressure specified for
u
post-lubrication (see chapter Monitoring during operation / Lubricating
oil pressure).
