The apparatus has a nozzle body (5) injecting cleaning fluid into a flow channel of an exhaust turbine and comprising high pressure and low pressure nozzle orifices (51, 52). The nozzle body is designed such that exhaust velocity of the cleaning fluid at an outlet of the high pressure nozzle orifice differs from exhaust velocity of the fluid at an outlet of the low pressure nozzle orifice during injecting the fluid. A restrictor (53) is arranged in a supply line that supplies the fluid to the high pressure nozzle orifice. The nozzle orifices comprise different sized cross section areas. |
