Definitions

  • the invention relates to the cleaning of a rotor or rotor components within a housing.
  • a gas turbine As an example of a rotor, which is arranged in a housing, here a gas turbine is mentioned, in which the hot gas part has a rotor, which can deposit on the gas turbine blades of the rotor combustion residues. Such debris can attack the coating or turbine blade or clog cooling holes and must therefore be removed.
  • the object is achieved by a method according to claim 1.
  • FIG. 1 the invention is shown schematically.
  • the rotor 4 remains within its housing. 7
  • the rotor 4 is supported by a shaft 13.
  • the cavity between the walls 10 ', 10 "in the housing 7 is flooded through corresponding accesses in the housing 7 or the walls 10', 10" as completely as possible with a cleaning liquid 16.
  • the cleaning liquid 16 is used to remove the dirt on the rotor 4, here turbine blades 120, 130 (FIG. Fig. 2 ) of the rotor 4.
  • the rotor 4 can be rotated by the shaft 13, because it is preferably still connected to a generator or is coupled.
  • FIG. 1 shows only the rotor 4, but in a gas turbine engine, the walls 10 ', 10 "can also be introduced at the inlet of the compressor and at the hot gas outlet, ie after the gas turbine, so that the compressor blades can also be cleaned.
  • the housing 7 need not be completely flooded, but only half, if only the blades are to be cleaned.
  • the cleaning liquid 16 can be exchanged and / or rinsed for improved cleaning, even during the ultrasound excitation.
  • the FIG. 2 shows by way of example a gas turbine 100 in a longitudinal partial section.
  • the gas turbine 100 has inside a rotatably mounted about a rotation axis 102 rotor 103 with a shaft 101, which is also referred to as a turbine runner.
  • a compressor 105 for example, a toroidal combustion chamber 110, in particular annular combustion chamber, with a plurality of coaxially arranged burners 107, a turbine 108 and the exhaust housing 109th
  • the annular combustion chamber 110 communicates with an annular annular hot gas channel 111, for example.
  • Each turbine stage 112 is formed, for example, from two blade rings. As seen in the direction of flow of a working medium 113, in the hot gas channel 111 of a row of guide vanes 115, a series 125 formed of rotor blades 120 follows.
  • the guide vanes 130 are fastened to an inner housing 138 of a stator 143, whereas the moving blades 120 of a row 125 are attached to the rotor 103 by means of a turbine disk 133, for example. Coupled to the rotor 103 is a generator or work machine (not shown).
  • air 105 is sucked in and compressed by the compressor 105 through the intake housing 104.
  • the compressed air provided at the turbine-side end of the compressor 105 is supplied to the burners 107 where it is mixed with a fuel.
  • the mixture is then formed to form the working medium 113 in the combustion chamber 110 burned. From there, the working medium 113 flows along the hot gas channel 111 past the guide vanes 130 and the rotor blades 120. On the rotor blades 120, the working medium 113 expands in a pulse-transmitting manner, so that the rotor blades 120 drive the rotor 103 and this drives the machine coupled to it.
  • the components exposed to the hot working medium 113 are subject to thermal loads during operation of the gas turbine 100.
  • the guide vanes 130 and rotor blades 120 of the first turbine stage 112, viewed in the flow direction of the working medium 113, are subjected to the greatest thermal stress in addition to the heat shield elements lining the annular combustion chamber 110. To withstand the prevailing temperatures, they can be cooled by means of a coolant.
  • substrates of the components can have a directional structure, ie they are monocrystalline (SX structure) or have only longitudinal grains (DS structure).
  • As the material for the components, in particular for the turbine blade 120, 130 and components of the combustion chamber 110 for example, iron-, nickel- or cobalt-based superalloys are used. Such superalloys are for example from EP 1 204 776 B1 .
  • EP 1 306 454 EP 1 319 729 A1 .
  • the blades 120, 130 may be anti-corrosion coatings (MCrAlX; M is at least one element of the group iron (Fe), cobalt (Co), nickel (Ni), X is an active element and is yttrium (Y) and / or silicon , Scandium (Sc) and / or at least one element of the rare earth or hafnium).
  • M is at least one element of the group iron (Fe), cobalt (Co), nickel (Ni)
  • X is an active element and is yttrium (Y) and / or silicon , Scandium (Sc) and / or at least one element of the rare earth or hafnium).
  • Such alloys are known from the EP 0 486 489 B1 .
  • EP 0 412 397 B1 or EP 1 306 454 A1 are known from the EP 0 486 489 B1 .
  • a thermal barrier layer may be present, and consists for example of ZrO 2 , Y 2 O 3 -ZrO 2 , ie is not, partially or completely stabilized by yttrium oxide and / or calcium oxide and / or magnesium oxide.
  • suitable coating processes such as electron beam evaporation (EB-PVD), stalk-shaped grains are produced in the thermal barrier coating.
  • the vane 130 has a guide vane foot (not shown here) facing the inner casing 138 of the turbine 108 and a vane head opposite the vane root.
  • the vane head faces the rotor 103 and fixed to a mounting ring 140 of the stator 143.
