Revision C

April 2018

5.4.1

Wet cleaning turbine and nozzle ring during
operation

Prerequisites for wet cleaning of turbine

The following operating state and prerequisites have been tested and
approved by ABB Turbo Systems for the cleaning process:

The engine has just been started or the engine load has been reduced
as far as possible (best cleaning is achieved at a load level of roughly
10 ... 15%).

As soon as the turbine inlet temperature is stable and below 430 °C,
wait at least another 10 minutes for the charger parts to cool down.

Start cleaning cycle according to following description Wet cleaning
procedure.
