conditions. In general, cleaning should be carried out every 50 to 200
operating hours.
Cleaning intervals
Should the specified cleaning intervals prove incompatible with engine

Turbine components are cleaned during operation using the wet cleaning
processes described in the following. These have been tested and are
approved by ABB Turbo Systems.
The turbine casing design and the type of turbine casing sealing are
decisive for the choice of cleaning method.
