Abstract
In a method for keeping clean and/or cleaning, during operation, the inner surfaces affected by deposits of a gas turbine including a turbine part (2) and an upstream compressor part (3), the "fouling" is effectively prevented without disturbing the operating procedure by subjecting the inside of the gas turbine (1) to sound waves, at least at times, in particular from sound transmitters (8a, . . . , 13b) arranged on the gas turbine (1).
