7.4.3

Wet cleaning of turbine blades and nozzle ring

Prerequisites

The following operating state and the following prerequisites have been tested and ap-
proved by Turbo Systems for cleaning operations:

u

Set the engine load between 20 … 50% so that the turbine inlet temperature is between
380 … 430 °C.

Fig. 27: Load/time chart

u

Once the turbine inlet temperature of the high-pressure stage is stable and lying below
430 °C, wait at least another 10 minutes for the parts of the low and high-pressure stages
to cool down.

u

Start the cleaning cycle according to the following description Wet cleaning operation.

u

Only clean the low-pressure stage (Cleaning LP stage) if the low-pressure stage is con-
figured with this option. If this is not the case, drying is initiated directly after cleaning of
the high-pressure stage (Cleaning HP stage).
