Table 13: Turbine wet cleaning, recommended operating state
*) The temperature at the turbine inlet can be up to 100 ℃ higher than the exhaust gas
temperature after the cylinder. This must be taken into account when setting the operating
point before cleaning.
If necessary, the engine performance must be reduced to meet these conditions.
The cleaning cycle can be started when the above conditions are fulfilled.
6.3.6 Carrying out wet cleaning of the turbine
Inadmissible thermal stress and flooding of the turbine
Smaller amounts of water can lead to an inadequate cleaning result. Larger
amounts of water lead to inadmissible thermal stress on the turbine
CAUTION
components and can cause flooding of the turbine.
It is imperative that turbine cleaning parameters are observed.

Maximum temperature at turbine inlet during cleaning
During cleaning, the temperature at the turbine inlet will rise and may strain
the material significantly.
CAUTION
Make sure the maximum temperature at the turbine inlet is not exceeded
