  • Rotary machines for example turbo or compressor stages of gas or steam turbine plants, generally have fixed guide vanes and rotor blades rotating about an axis of rotation for targeted expansion or compression of gases or gas mixtures, which are usually exposed to high process temperatures and thus have to withstand high thermal loads , In addition to the thermal load, it is in particular the rotating about the axis of rotation blades, which are also exposed to high, caused by the centrifugal forces mechanical loads.
  • the blade root is preferably interspersed with a plurality of radially-oriented cooling passages which extend innately through the entire extension of the blade blade for effective cooling of the blade.
  • For cooling air supply serve cooling air supply channels provided on the rotor side, is fed by the cooling air into the rotor blade radially passing through the cooling channels.
  • Such a cooling air supply system thus requires a rotor having a plurality of radially oriented cooling air ducts, the individual cooling ducts of which must be exactly aligned by appropriate positioning of the individual rotor blades in alignment with the radial cooling ducts provided in the rotor blade root. Even the slightest misalignments between the blade root and the rotor unit can permanently impair effective cooling of the blade, which is considerably reduced by the life of the blade.
  • a cooling air feed stream enters the axially oriented cooling air supply channel within the blade root, from which branch off individual cooling air channels projecting radially into the blade airfoil. Since blades are usually produced as part of a casting process, it is used to form such in a casting inside cavities of the so-called Gusskem technique, which allows in particular the rotor blade axially projecting through the cooling air supply duct and the individual, the blade inside radially at least partially enforcing individual cooling channels to produce.
  • flow passages are provided which provide the axially directed cooling air feed stream into the radially extending cooling passages to redirect within the blade.
  • the flow gaps to be provided for this purpose which cause both a change in direction and also a flow distribution of the cooling air feed stream directed axially into the blade root, are subject to production-related structural tolerances by which precise guidance and division of the cooling air flow onto the individual cooling ducts extending radially along the blade airfoil only occur an unsatisfactory accuracy is possible.
  • the invention is intended to remedy the situation, so that the invention is based on the object to optimize the cooling air distribution to the individual radially oriented cooling channels within a blade. Also, the measures to be taken for this purpose should not cause costly manufacturing or assembly steps and have robust properties that can withstand the high demands in terms of thermal and mechanical stress within such about a rotation axis rotating components.
  • the further embodiments relate to the case of a blade which is mounted along a rotor unit of a gas or steam turbine plant and can be used in a turbo stage or compressor stage.

  • the distribution plate With the aid of the distribution plate, it is thus possible to divide previously calculated volume proportions of cooling air, which are adapted to the respective rotating blade, onto the individual cooling channel regions extending radially along the blade airfoil. Such an exact division of the cooling air flow is not possible due to the manufacturing tolerances unavoidably associated with the casting process, with the exclusive use of flow-related profiles produced by casting.
  • Cooling air supply ducts provided at least two axially spaced apart shoulder elements, the radially opposite the opening edge of the opening of the at least one cooling channel region slightly spaced, and with this limits an insertion slot, in the axial becamertiges insertion into the cooling air supply duct, the distribution plate experiences a preferably flush snug fit. It should be noted at this point that it is preferable to provide a plurality of cooling channel regions which pass radially through the rotor blade and are separated from one another by intermediate walls.
  • the intermediate walls open via a respective opening edge facing the cooling air supply channel, which encloses the opening of the respective cooling channel region extending radially inward.
  • the distributor plate made of a material and with a material thickness to manufacture, so that the bending moment of the distribution plate by the resulting by rotation and on The distribution plate attacking centrifugal forces is exceeded and the distribution plate is able to conform to the casting geometry of the opening edges downright.
  • This nestling process can also be supported in a further preferred embodiment in that the distribution plate has locally limited material weakenings, for example in the form of mechanical indentations or cracks. Also, such material weakenings can be generated by deliberately changing the microstructure in the distribution plate. Such points of reduced strength are distributed along the distribution plate, preferably in areas near the opening edges where it is necessary to make a fluid-tight connection.
  • the distribution plate fixed at one end or both ends to the inner structure of the blade root in the area of the cooling air supply channel, for example by means of a soldered or welded connection.
  • the joints required for this purpose are easily accessible for mounting purposes axially through the cooling air supply channel, so that the required assembly effort is not significantly increased.
  • the axially extending through the blade root fully extending cooling air supply channel is open on both sides with respect to the blade root, it is necessary to close an axial-side opening fluid-tight.
  • a simplest embodiment provides, by corresponding bending of an end region of the distribution plate to provide a frontal closure of the cooling air supply duct, wherein the distribution plate at least in the region of its end bent-over plate portion with the inner wall of the Cooling air supply duct to be welded or soldered.
  • a fixation in this regard could adversely affect the required at least in the state of rotation adjusting fluid-tight connection between the distribution plate and the at least one opening edge, so that a further preferred embodiment instead of a fixed disposal of the distribution plate in the region of the bent Verteilplattenabiteses a separate end plate provides , which closes the cooling air supply channel axially on one side fluid-tight.
  • FIG. 1 the cross-section through a blade 1 is shown, which is arranged rotatably about a rotation axis 2 of a rotor unit integrated in a gas turbine arrangement.
  • the rotor blade 1 has a rotor blade root 3 which can be frictionally connected to the rotor unit (not shown) via a correspondingly formed joining contour (fir tree structure - not shown). Radialward joins to the blade root 3, the blade 4, in the interior of which cooling channel areas K1 to K4 are provided.
  • the cooling channel areas K1 to K4 are provided in the region of the blade root 3 extends an axially, ie parallel to the axis of rotation 2, oriented cooling air supply channel 5, which first extends through the entire axial width of the blade root 3.
  • shoulder elements 6 are provided, which are machined out of the casting material by means of the casting process, with which the entire blade 1 can be produced, from which the remaining blade material is made.
  • the shoulder elements 6 have upper surface portions 61 which are slightly spaced from each other on the radial side so-called opening edges 71.
  • the opening edges 71 surround openings 7 facing the cooling supply channel 5, to which the cooling channel areas K1 and K2, which are bounded in each case by cooling channel area walls 72, adjoin the radial side.
  • a distribution plate 8 is provided in which appropriately positioned and dimensioned passage openings 81 are introduced.
  • the passage openings 81 are correspondingly provided in the opening region of the openings 7.

  • the passage openings 81 provided in the opening region of the cooling channel region K1 allow a cooling air flow on the radial side through the cooling channel K1, which provides an outlet opening A at the upper flank of the blade 4, through which the cooling air escapes into the hot gas channel H.
  • the cooling air entering through the passage openings 81 into the cooling channel region K2 is for the most part diverted through corresponding flow guiding means 9 into the cooling channel region K3, which is adjoined by the cooling channel region K4 in the flow direction (see flow arrows).
  • the distribution plate 8 ensures that the cooling air flow flowing downwards in the cooling channel region K3 is deflected in its entirety into the cooling channel region K4 extending radially upwards.
  • the distribution plate 8 gas-tight or fluid-tight against the corresponding opening edges 71 and the edge contour 10 hugs.
  • care must be taken to ensure that no leakage flows occur between the distribution plate 8 and the opening edges 71.
  • it is necessary to dimension the distribution plate 8 and to select in terms of their plate material that it is firmly pressed flush with the corresponding opening edges 71 and the edge contour 10 of the centrifugal forces caused by the rotation about the rotation axis 2.
  • the distribution plate 8 lies loosely in the between the surface portions 61 of the shoulder elements 6 and the opening edges 71 and the edge contour 10 limited entrance slot 11 (see FIG. 2 ).

  • the opening edges 71 enclose with the surface portions 61 of the shoulder elements 6 an insertion slot 11, along which the distribution plate 8 which is planar in shape in the initial state can be pushed in axially.
  • the distribution plate 8 otherwise remains lying loose on the surface portions 61 of the shoulder elements 6.
  • a cover plate 12 to the in FIG. 2 used left inlet opening in the cooling air supply duct 5 and welded or soldered in edge regions with the blade root 3. Due to the one-sided, gas-tight closure of the cooling air supply duct 5, the cooling air feed flow S entering from the right side into the cooling air supply duct 5 experiences a stowage effect within the cooling air supply duct 5, whereby the cooling air feed stream S is driven through the passage openings 81 provided in the distribution plate 8. Size and arrangement of the individual passage openings 81 define the volume flow of the cooling air flow entering the respective cooling passage areas K1 and K2.
