Definitions
- the invention relates to a turbine plant, in particular a Gas turbine plant.
- a gas turbine plant a plant understood that a combustion chamber and one of the combustion chamber downstream designated as a gas turbine turbine includes.
- a combustion chamber and one of the combustion chamber downstream designated as a gas turbine turbine includes.
- the combustion chamber is burned a fuel gas in a gas space, and the hot gas generated thereby is supplied to the turbine and flows through these.
- the flow path of the hot gas through the Turbine is also referred to below as the gas space.
- the turbine has fixed vanes extending from extend radially outward into the gas space, as well as on a Runners designated shaft mounted blades, the extending from the rotor radially outward. Longitudinal the turbine considered grab the vanes and the Blades of teeth tooth-like.
- the turbine has in usually several turbine stages, with one in each stage Vane ring is arranged, i.
- vanes are arranged side by side in the circumferential direction of the turbine.
- the individual vane rings are in axial Direction arranged successively.
- the gas space is common clad with plate elements.
- the plate elements formed by so-called foot plates of the individual vanes.
- the gas area of the combustion chamber and the turbine should as possible be tight. Therefore, small losses of leakage between aspired to the individual plate elements. Especially should prevent leakage losses between two turbine stages become. Due to the large temperature ranges in the gas space There is the problem that a sealing strains the individual Record and bridge plate elements without that the seal is significantly impaired. reinforced This problem is caused by the fact that both the tiles and the foot plates of the vane not at their edges attached to adjacent plate elements, so that the Plate edges are more or less free and a bend due subject to thermal expansion. The tiles for example, are usually attached in their middle and bend under spherical stress approximately spherical. A seal must therefore - also because of the axial direction conical formation of the combustion chamber and the turbine - both allow axial as well as radial mobility.
- the invention has for its object to provide a seal that overcomes the disadvantages described.
- the object is achieved according to the invention by a turbine plant, in particular a gas turbine plant, with a gas space which is bounded on the outside by adjacent plate elements, wherein each sealing element is associated with adjacent plate elements and this connects at their rear side facing away from the gas space in a clip-like manner.
- the main advantage here is in the bracket-like To see the design of the sealing element.
- the sealing element So spans the two plate elements. In thermal Strains the sealing element follows the plate elements without to release a gap. The seal by the sealing element is therefore largely unaffected by thermal strains.
- the sealing element has two legs, each in a groove of adjacent plate elements to grab.
- a manufacturing technology is easy to realizing attachment of the sealing elements allows.
- the sealing element preferably a mobility of the plate elements both in the axial and in the radial direction.
- the sealing element is therefore both in the axial and in the radial direction especially elastic.
- Under axial direction This is an extension in the longitudinal direction of the turbine system and in the radial direction an extension perpendicular understood to the longitudinal axis.
- the groove extends from the back of each Plate element in this substantially radially into it.
- the legs thus protrude radially outward from the grooves.
- This configuration of the groove allows a simple Production and in particular a high accuracy, for example by grinding or eroding.
- the advantage of the arrangement on the back you can see that the groove in the With regard to the problem of thermal strains no special Must have shape. Groove and sealing element can therefore be adjusted very closely to each other, so that very little Leakage gap can be achieved.
- the sealing element preferably constructed in several parts.
- the sealing element is U-shaped trained, which both manufacturing technology and assembly technology easy to realize.
- the sealing element has this corrugated Structure in multiple directions so that it expands into can accommodate different directions.
- the sealing element double S-shaped.
- the sealing element between arranged adjacent tiles of a combustion chamber This will be achieved a secure seal between the tiles, even if these are spherical due to the thermal load to bend.
- the sealing element between the foot plates of adjacent vanes a turbine arranged, in particular between the Base plates of ladder blades of adjacent turbine stages.
- the individual foot plates are therefore in the axial or longitudinal direction the turbine via clamp-like sealing elements together connected.
- a good seal of the plate elements both in the circumferential direction and in the axial direction between adjacent turbine stages is preferably for sealing in the axial direction described clamp-like sealing element and for sealing provided in the circumferential direction another sealing element.
- Dependence of the direction are thus in particular montage technical Reasons differently trained sealing elements used.
- the further sealing element preferably has a receiving area on, in which the plate elements hineineruxn.
- the sealing element is in cross section Seen H-shaped.
- the basic idea of this Embodiment is in the inverse of a conventional sealing principle to see, in which a sealing sheet in appropriate frontal grooves of the foot plates is introduced. This requires namely, usually a reinforcement of the edge of the Foot plates in the groove area. This is for a good cooling of the Foot plates problematic because of the different Material thicknesses a uniform cooling difficult to realize is and thermal stresses can occur.
- this sealing principle is now not the sealing plate inserted in the foot plates, but the foot plates are introduced into the sealing element. This eliminates the Need to reinforce the edge area of the footplate. The coolability is thus simplified and the foot plate is cooled homogeneously in all areas, so no thermal stresses occur.
- a turbine installation 2 in particular a turbine, comprises Gas Turbine Plant of a Turboset for a Power Plant for Power generation, a combustion chamber 4 and a turbine 6, the in the longitudinal or axial direction 8 of the turbine system 2 after the Brennkammmer 4 is arranged. Both the combustion chamber 4 as also the turbine 6 are cut in a partial area shown. This is a look into the gas space 10 of the combustion chamber 4 and in the gas space 12 of the turbine 6 allows.
- the combustion chamber 4 via a gas supply 14th a fuel gas BG supplied, which in the gas space 10 of the combustion chamber 4 is burned and forms a hot gas HG.
- the gas space 10 is formed with a plurality of plate elements Tiles 13 lined.
- the hot gas HG flows through the turbine 6 and leaves this as cold gas KG over a Gas discharge 16.
- the hot gas HG is in the turbine 6 over Guides 18 and blades 20 out. It will a shaft 22 is driven, on which the rotor blades 20 are arranged are.
- the shaft 22 is connected to a generator 24.
- the blades 20 extend radially from the shaft 22 outward.
- the vanes 18 have a foot plate 32 and a blade 21 attached thereto.
- the vanes 18 are each outside of the turbine via their foot plates 32 6 attached to a so-called vane support 26 and extend radially into the gas space 12.
- Several of the blades 20 as well the vanes 18 are each combined into a wreath, wherein each vane ring is a turbine stage represents. In the embodiment of FIG 1 is the second turbine stage 28 and the third turbine stage 30 by way of example shown.
- the foot plates 32 of the individual vanes 18 are also as the tiles 13 formed as plate members, which together both in the axial direction 8 and in the circumferential direction 33 of the turbine 6 adjacent to each other and the gas space 12th limit.
- the marked with a circle in FIG 1 Position is shown enlarged in Figures 2 to 4.
- the too These figures described seal between two particular in the longitudinal direction 8 juxtaposed foot plates 32 can be used analogously as a seal for the tiles 13 of the combustion chamber 4 transmitted.
- the conventional one shown here takes place Variant the seal without special sealing element solely due to an overlap of adjacent foot plates 32.
- the two foot plates 32 stepped.
- the sealing effect thus depends largely on the expansion behavior the foot plates 32 from.
- the foot plates 32 as shown in FIGS 2 to 4 point to their from Gas chamber 12 facing away from the rear 39 each a Verhakungselement 40, over which the foot plates 32 on the vane carrier 26 (see FIG 1) are held.
- Each foot plate 32 has typically two interlocking elements 40 which are different are designed and both a mobility allow in the axial direction 8 and in the radial direction 36.
- FIG 3 another conventional sealing arrangement a sealing plate 41, which in grooves 44 of the adjacent Foot plates 32 is inserted.
- the grooves 44 are included incorporated into the end faces 46 of the foot plates 32.
- she have an opening angle ⁇ of about 15 ° to a To allow mobility of the foot plates 32 in the radial direction 36.
- a leakage gap 38 is formed, with stretching as a result of thermal stress varied. This variation is partly due to the foot plates 32 expand faster than the vane carrier 26 to which they are attached.
- the problems of temperature dependence of the leakage gap 38 occurs in the novel embodiment according to 4 not on. After that are in the area where the two Foot plates 32 adjacent to each other in the rear 39 grooves 44 incorporated, which is substantially radially in the Foot plates 32 extend. It should be emphasized that the grooves 44 in FIG 4 in contrast to those of FIG 3 parallel Side walls 50 have. This allows a particularly simple Production of the grooves 44.
- a U-shaped sealing element 42 A In the grooves 44 is a U-shaped sealing element 42 A with his two legs 52 introduced and in particular attached. The attachment is done for example by clamping action or by welding.
- the sealing element 42A is in particular designed as a sheet metal element. Its legs 52 extend essentially in the radial outward direction, so that the two legs 52 connecting bow 54th is spaced from the back 39.
- This stretched version allows an elastic behavior of the sealing element 42A, i. it follows the thermal expansions of the foot plates 32.
- the thermal mobility of the foot plates 32 is thus ensured by the bendable or stretchable sealing element 42A.
- the mobility is thus independent of the special configuration of the grooves 44, so this very can be adapted to fit the legs 52. Between the leg 52 and the grooves 44 is therefore not or only a very small leakage gap 38 is formed, which is independent from the thermal stress of the foot plates 32.
- FIG. 5 is a sealing element 42B is formed from two separate legs 52, each having a bow 54 and over overlap a circumferential length L.
- the multipart training the sealing element 42B simplifies assembly, for example the individual legs 52 already before mounting the Guide vanes 18 simply into the corresponding grooves 44 of the respective foot plates 32 are attached and these subsequently attached to the vane support 26.
- the common The circumferential length L is chosen as large as possible in order to the leakage gap 38 formed between them for all temperature and to keep operating conditions low.
- a sealing element 42D is corrugated Structure 58 provided that the simple designed bow 54 replaced according to Figures 4 to 6.
- This corrugated structure 58 preferably extends in several directions, in particular in the two directions parallel to the foot plates 32nd
- the legs 52 may be corrugated.
- the Seal member 42D is thus in the manner of a bellows trained and allows even large thermal strains to absorb in multiple directions without the leakage gap 38 is increased.
- the sealing elements 42A to 42D combine montagetechni Service Reasons preferably the base plates 32 of vanes 18 adjacent turbine stages 28,30. To also in the circumferential direction 33 a good and easy to install seal to achieve is in the circumferential direction 33 adjacent to each other Guide vanes 18 of a vane ring another Sealing element 60 is provided.
- the further sealing element 60 is shown in FIG 8 preferably in Seen cross-section H-shaped and has two Longitudinal leg 62, which via a transverse leg 64 with each other are connected. Between the two longitudinal legs 62 are two separate receiving areas 65 from the transverse leg 64 formed, in which the foot plates 32 extend. The margins 66 of the foot plates 32 are approximately perpendicular to the gas space 12 bent outward and nestle immediately to the transverse leg 64 at.
- This embodiment with the receiving areas 65 for the foot plates 32 advantageously enables one over the entire foot plate 32 homogeneous material thickness, so that a uniform cooling of the base plate 32 is ensured and Thermal stresses in the base plate 32 do not occur.
- FIG 8 For cooling the foot plates 32 is in particular a closed Cooling system 68 provided with steam as a coolant, the in FIG 8 is shown in fragmentary form.
- This closed Cooling system 68 has an inflow channel 70 and a Return flow 72 on.
- the inflow channel 70 is between a outer baffle 74 and a baffle 76 is formed, which arranged between baffle 74 and the base plate 32 is.
- the baffle 76 has flow openings 78 which are formed in the manner of nozzles, so that via the inflow channel 70 supplied coolant along the illustrated Arrows in the return flow passage 72 passes. Due to the nozzle-like Operation of the flow openings 78 is the Coolant at high speed against the backside 80 the foot plate 32 is steered, so that an effective heat transfer realized between the coolant and the base plate 21 is.
- the baffle 76 is via support members 82, for example in the form of welds or welding bars, against the foot plate 32 supported and kept spaced.
- the baffle plate 70 is directly attached to the side edge 66 of the foot plate 32, welded in particular, and the baffle 68 is on Baffle plate 70 attached.
- a flow path 84 in the form of a leakage gap formed, so that remote from the gas space 12 outside space For example, air over the flow path 84 in the gas space 12 can flow and thus the sealing area, So the sealing element 60 and the side edges 66 cools.
