Description

The invention relates to a component of a steam turbine plant, for the application of superheated steam, with a hot steam space facing hot side, which has a contour and a fairing. The invention further relates to a steam turbine plant, a use and a manufacturing method.

A steam turbine plant usually consists of the steam turbine as such and a steam turbine periphery. Among other things, the periphery serves to supply and remove superheated steam to and from the steam turbine. The input-side periphery of the hot steam turbine is supplied at a high temperature and pressure to a turbine housing. For this purpose, the superheated steam is first fed to an inflow region of the turbine, which essentially extends between a connection of a steam boiler to the turbine and the beginning of a blading in the housing or on the rotor of the turbine. In the steam turbine, the superheated steam is conducted past the turbine blades as a working medium with cooling and expansion and in this way drives the rotor of the turbine while releasing its thermal and kinetic energy. The rotation can be used to drive a generator and there to generate electrical power. The relaxed and cooled working fluid may be in the form of cooled and relaxed vapor in the exit periphery, e.g. B. via a condenser, recirculate.

In order to increase the efficiency of such a steam turbine plant, it is necessary inter alia to increase the pressure and the temperature of the working medium, ie the superheated steam. This has a variety of additional or increased stresses the materials used in components with high thermal loads, in particular in the periphery of the turbine system, the inflow, housing or rotor area of the turbine of the turbine system result. Because at high operating temperatures it comes z. B. due to chemical reactions of the material with the working fluid, inter alia, to an increased oxidation rate, which leads to an increased extent to scale formation. This is undesirable and presents a variety of problems, including the sealing behavior of the particular component or downstream components.

In order to solve such problems, it has hitherto been necessary to use higher-grade materials, in particular in the periphery of the turbine system, the inflow region and / or the housing or rotor region of the turbine of the turbine plant for the piping and / or collecting components. High temperatures of the components, however, usually also result in a lowering of the permissible mechanical stress, which in turn results in the use of even higher quality materials not only in the component itself but also in its constructive anchoring.

Higher grade materials are not only costly, but also labor intensive in terms of their processing and use. Principles of cooling for components of a steam turbine plant are known in principle, but have losses in the efficiency of the entire system result.

It has therefore begun to install, in part, especially for components that are exposed to high thermal loads, insulation. These have hitherto been applied, for example in pipelines, boilers or collectors of the periphery, as part of a spraying process in which a coating powder is thermally sprayed on.

In addition, it is known to install heat-insulating fabric on a hot steam space facing hot side of a component of the periphery. Such thermal insulation materials can usually be applied in layers of high thickness and would be well suited in principle. However, in the context of higher operating temperatures and higher operating pressures meanwhile the flow characteristics of steam flows in and / or on a component, eg. B. already due to the flow rate, so aggressive that said thermal insulation materials prove to be insufficient and already after a short time, z. B. by erosion, other abrasion and / or oxidation, destroyed and / or can be replaced. This effect is reinforced by thermal shock stresses that make the materials brittle or at least create tensions. Dissipated thermal insulation materials then enter the flow of the working medium and can result in further enhancement of erosion damage in both the periphery and the turbine of the turbine plant.

It would be desirable to have a cladding with simultaneously high thermal insulation properties and high abrasion resistance. So far, increasing the thermal insulation by increasing a thickness of a thermal barrier coating in the manner explained above leads to a reduction in mechanical resistance. On the other hand, increasing the mechanical resistance by reducing the thickness of a heat-insulating layer results in lower thermal resistance since the thermal insulation also decreases with decreasing thickness.

At this point, the invention, whose object is to provide a component of a steam turbine plant for exposure to superheated steam, a steam turbine plant and a use and a manufacturing method, according to the same thermal and mechanical resistance of the component, even at elevated temperature and pressure parameters a superheated steam, especially at temperatures above 600 ° C and / or pressures above 250 bar, is advantageously improved.

The object with regard to the component is achieved by an initially mentioned component, in which, according to the invention, the cladding is arranged in the region of the hot side of the component and is formed by a number of shaped pieces adapted to the contour, wherein a shaped piece is in each case formed as a metal and ceramic component. Composite layer is formed with at least one metal layer and at least one ceramic layer.

The invention is based on the consideration that, in principle, a physical separation of a surface of a component from a superheated hot steam space is advantageous, ie the invention is based on providing a contour of a hot side of the component facing a hot steam space with a cladding. However, in contrast to the prior art, the invention has also recognized that due to the thickness of such a cladding, if these, in order to achieve increased efficiencies, at high pressure and temperature parameters, in particular> 600 ° C and / or> 250 Bar, a working medium is exposed to significant restrictions on the resistance of the component comes. With increasing thickness of a thermal insulation increases their thermal insulation effect, but it decreases in the manner explained above, their mechanical resistance, especially in thermal shock stress. With decreasing thickness of the cladding, the thermal insulation effect decreases and increases the mechanical resistance under the influence of a working medium, which has a high flow rate and high reactivity due to high temperatures and high pressures. The invention solves this conflict by the use of a lining in the form of a number of contour-adapted moldings which have a metal and ceramic composite layer on the hot side.

As a first aspect of the invention, it has been found that in the case of a metal and ceramic composite layer which is formed from a metal layer and a ceramic layer, a greater layer thickness can be achieved. The layers of the composite layer are advantageously cohesively, in particular intimately, connected to one another. But they can also be connected by methods such as screwing, plugging or riveting. That is, it can be for the case of a composite layer increase the thermal insulation effect of the cladding, without reducing the mechanical resistance. The cladding according to the new concept proves to be particularly abrasion-resistant and erosion-resistant in a great variety of variants.

Moreover, as regards a second aspect of the invention, it has been found that the attachment of a panel, depending on the extent of a component in the form of a number or a plurality of shaped pieces on the contour, not only increases the mechanical resistance of the panel, but also better liner adhesion guaranteed on the hot side and also insensitive to changing temperature and mechanical stress in the high temperature and high pressure range. Surprisingly, just with turbine housings, z. As in the inflow of a turbine system and in line and / or collective components shown that because of their often crooked and inaccessible design, a plasma spraying or other thermal spraying method prove less reliable than a particularly advantageous recognized cladding in the form of a variety of contour-matched fittings. A shaped piece may preferably itself be curved, curved or bent such that it is z. B. fits perfectly to a contour and contour contoured in this sense. This can be advantageous in particular for small components. In particular, in the case of large components, a shaped piece itself may possibly be planar. Nevertheless, the fairing contour contoured be, for example, characterized in that at isolated points of the contour sufficiently small fittings are attached.

The cladding, which according to the new concept provides for a combination of the two aspects mentioned above, avoids the above-described disadvantages of the prior art. The mechanical, thermal and chemical stress on the hot side of the component is reduced by the cladding according to the new concept. This opens up the possibility to use current materials for higher working medium parameters or to use less expensive materials with the same parameters.

In addition, in particular, the thermal insulation inside the component, the minimization of the temperature gradient from the inside to the outside, the minimization of the heat loss as well as the chemical resistance, in particular the corrosion resistance, proves to be improved over the prior art. These and other advantages are particularly developed by advantageous developments of the invention, which can be found in the dependent claims and indicate in detail possibilities to realize a component of a steam turbine plant for application of superheated steam according to the new concept.

According to a first variant, the ceramic layer may be closer to the hot side than the metal layer. This has the advantage that the metal layer serves as a holder, fixing and counter bearing of the ceramic layer. That is, practically, the metal layer within the composite layer serves as a supporting layer for the ceramic layer. This increases the mechanical resistance of the composite layer as a whole, especially at high mechanical stress in the context of increased working medium parameters. The metal layer recessed behind the ceramic layer is also exposed to less corrosion.

According to a second variant, the metal layer may be closer to the hot side than the ceramic layer. In this case, the metal layer within the composite layer serves primarily as an abrasion and / or erosion protection for the ceramic layer. That is, the ceramic layer is less mechanically stressed by the flow, especially at high flow parameters.

In a third variant, the advantages of the two aforementioned variants are combined by arranging the ceramic layer between an immediately adjacent first metal layer and second metal layer. Here, the support property of the first metal layer on the cold side is combined with an erosion-proof property of a second metal layer on the hot side.

In principle, as part of a fourth variant, the metal layer could also be arranged between an immediately adjacent first ceramic layer and the second ceramic layer. In this case, the metal layer can serve as an inner support layer and is simultaneously protected by the ceramic layers against chemical and in particular corrosive stresses, in particular on the hot side.

Which of the four variants proves to be advantageous in an individual case is to be decided with regard to a specific application. It has been found, in particular, that the thickness of a cladding in the context of the new concept, ie in the context of a contour-adapted fitting with a composite layer which protects against mechanical, thermal and chemical stresses, can already be realized with a composite layer thickness above 2 mm. However, this is a thickness range that would already result in cladding according to the prior art to increased thermal shock sensitivity, especially when the component is exposed to superheated steam at temperatures above 600 ° C and pressures above 250 bar.

Further developments of all four variants can be taken from the further subclaims and are otherwise described by way of example with reference to the drawing by way of example in detail.

The invention leads in particular to a steam turbine plant with a component of the kind explained above. In particular, use of the component as a conduit and / or collecting component in the context of a periphery of the steam turbine plant proves to be advantageous. In addition, use of the component also proves to be advantageous in the case of a housing part, in particular in the inflow region of a steam turbine of a steam turbine plant. The inflow can be understood in this context itself as a line component.

It may also be advantageous to use a trim fitting with a metal and ceramic composite layer on a hot side in the rotor and blade area of a steam turbine.

a sectional perspective view of an inflow according to one of the above-mentioned particularly preferred embodiments.

1A shows a line component 10 in the form of a pipeline of a steam turbine periphery or in the inflow region of a steam turbine for acting on superheated steam, wherein the steam turbine is not shown in detail. A component can for example be made of 9-12% Cr steel material. The line component 10 has a hot steam space 1 facing hot side 3, which has a contour 5 and a panel 7. The cladding 7 is formed in the form of a plurality of moldings 27 shown in FIG 3 on the contour 5, wherein the cladding in the FIG 1A shown in section and in Figure 3 as a perspective sectional view with respect to the fittings 27 is explained in more detail and shown.

A not shown in FIG 1A Shaped piece 27 of the panel 7 is, as the section of the panel shows, adapted in its curved shape of the curved contour 5. That is, the shaped piece 27 is curved substantially like the contour 5 and extends parallel to the contour 5 and faces the hot side 3 of the line component 10. On the hot side 3, the molding 27 has a metal and ceramic double composite layer 9, which is formed from exactly one metal layer 11 and exactly one ceramic layer 13. In particular, the metal layer 11 and the ceramic layer 13 are connected to one another in a materially cohesive manner.

In the context of the embodiment of a line component 10 shown in FIG. 1A, the hot side 3 has the metal and ceramic composite layer 9 directly on the contour 5 of the component body 23 of the component 10. The composite layer 9 is fixed mechanically as such on the contour 5. In the manufacturing process, this can be done for example by a dowel, screw or welded connection. The panel 7 consists of the composite layer 9. It has namely have shown that in the periphery of steam turbines for the temperature range below 1000 ° C, a molding with a composite layer 9 can be formed with a thickness greater than 2 mm. This is a measure that goes well beyond conventional thermal barrier coatings, yet the composite 9 is thermally and mechanically extremely durable. Conventional thermal barrier coatings in the form of a panel are plasma sprayed or vapor-deposited and can not be made for such a thickness - even if they do not have sufficient mechanical resistance, but which is possible in the context of the new concept by a corresponding fitting.

Advantageous thermal insulation effects can be achieved, which are dependent on the substance, porosity and thickness of the composite layer 9 and which can be carried out expediently within the scope of a particular application.

The erosion resistance is significantly improved by the fact that the metal layer 11 of the hot side 3 is closer than the ceramic layer 13. In addition, the metal layer 11 but also acts as an overhead support or fixation for the ceramic layer 13. The metal layer is presently provided as a high temperature resistant sheet metal material available, for. Example in the form of a sheet of a nickel-based alloy or other age-resistant alloy, which are suitable to wear a ceramic layer. As part of a manufacturing process of the composite layer 9, this can be easily adhered to a ceramic layer 13 or otherwise mechanically fixed, so that at the boundary layer 15, an intimate connection is formed. As a material for the ceramic layer, in particular a ceramic with particularly low thermal conductivity, z. As a zirconia-based ceramic, proved to be particularly advantageous. The ceramic layer serves for heat insulation. It is expediently also formed from a suitably pressure-resistant material. In this embodiment, an intimate connection the ceramic and metal layer are also dispensed with. In order to achieve a composite layer, a metal layer in the form of a sheet metal fitting can be pressed onto a first loose ceramic molding and hold the latter by a contact pressure on the contour.

A modification of this embodiment not shown here could also form a sandwich arrangement in the form of a metal-ceramic-metal composite layer. That is, in a modification of FIG 1A could be arranged on the back of the ceramic layer 13 and directly on the contour 5 a further metal layer in the form of a sheet metal layer for reinforcement. Such lying between the contour 5 and ceramic layer 13 sheet metal can be made in comparison to the illustrated metal layer 11 because of its lower temperature level in the operating case of a lower alloy sheet metal material, which has price advantages. The hot side 3 directly facing sheet is made of a higher quality sheet metal.

FIG. 1B shows a similar, second embodiment of a line component 20 according to the concept of the invention, in which, moreover, the parts corresponding to FIG. 1A are provided with the same reference symbols and will not be explained again. In contrast to the first embodiment of the line component 20 in FIG. 1A, in the second embodiment in FIG. 1B, the ceramic layer 13 is closer to the hot side 3 than the metal layer 11. Both layers 11, 13 are connected to one another at the borderline 15 in a materially bonded or optionally only form-fitting manner ,

In the present case, the hot side 3, the metal and ceramic composite layer 9 to form a clearance space 17 from the contour 5, ie, component body 23 and composite layer 9 are spaced from each other. The clearance space 17 is formed in the form of a coolant supply 19 and hollow. The lining 9 according to the second embodiment of the conduit component 20 in FIG. 1B, a cooling medium, in particular cooling steam, can flow behind it. The cladding 7 is thus configured in addition to the composite layer 9 with a cooling jacket, which is formed by the coolant supply.

Another modification of the cooling jacket will be explained with reference to FIGS. 2A and 2B. In turn, features with substantially the same function are provided with the same reference numerals.

2A shows a third embodiment of a line component 30, here in the form of an inflow. In this case, the ceramic layer 13 is formed as a thin heat-insulating layer on a metal layer 11. In this way, the heat input is limited by the superheated steam from the hot steam space 1 in the component body 23. In addition, in the third embodiment 30 of FIG 2A, the metal and ceramic composite layer 9 is provided with holes 21. The otherwise hollow distance space 17 serves as a coolant supply 19, wherein the coolant can escape through the bores 21 into the hot steam space 1 and thus forms a cooling boundary layer on it as a thermal insulating layer formed ceramic layer 13, which has an additional thermal insulation effect. In the present case, the bores 21 are arranged in the metal layer 11 and in the ceramic layer 13. Alternatively or additionally, the ceramic layer 13 may also have pores through which the cooling medium can escape into the hot steam space 1.

In FIG. 2B, as a fourth embodiment, a line component 40 is shown a modification of the third embodiment shown in FIG. 2A. Again, essentially the same reference numerals are used. The fourth embodiment of a conduit component 40 has a clearance space 40 which is filled with a porous and / or reticulated material 29. This can in particular a porous ceramic or a network of fiber material, for. Glass or metal fibers, be. The retention system formed in this way in the clearance space 17 is advantageously somewhat yielding and otherwise supports the composite layer 9 in an advantageous manner. Both a hollow spacing space 17, as in the third embodiment of a line component 30 of FIG. 2A, and a spacing space 17 filled with a restraint system in the fourth embodiment of a line component 40 according to FIG. 2B advantageously decouple the composite layer 9 formed by shaped bodies 27 from the component body 23. In this way, the panel 7 is particularly resistant to mechanical shocks z. B. by occurring in particular at a line component thermal instabilities, eg. B. attenuated during transient operations.

A similar decoupling of component body 23 and molded piece 27 can also be achieved by the sandwich structure explained in greater detail in conjunction with FIGS. 1A, 1B. In the first embodiment of a line component 10, in the context of a modification, an additional metal layer (not shown) between contour 5 and ceramic layer 13 can have the effect of an additional holder or fixing counter-layer. In this way, a direct connection of the composite layer 9 of the line component 10 to the component body 23 in a transient behavior, eg. As in thermal instabilities, damped.

Such a sandwich structure or a restraint system explained with regard to FIG. 2B considerably increases the operational reliability of a line component 10 or 40.

All panels 7 are fixed in the embodiments 10, 20, 30, 40 by a welded joint 25 on the component body 23. Alternatively or additionally, other types of connection, such as screws, rivets, staples or pegs o. Ä. Be provided. Moreover, it may also prove advantageous that one or more of the number of fittings 27 are interconnected by a net are. This may be, for example, metallic and sintered in a ceramic layer 13. As a result, the fittings are networked together and held better. The net may preferably be fastened to the contour 5.

3 shows a perspective view of the line components 10, 20, 30, 40, in which the panel 7 in the form of a plurality of fittings 27 are formed on the contour 5. Each of the shaped pieces 27 is adapted to the contour 5 in the region of the shaped piece 23.

In a particularly preferred embodiment of a production method, the component body 23 of the line component 10, 20, 30, 40 is initially provided. Thereafter, the cladding 7 is applied by applying a plurality of moldings 27 forming the cladding 7, each providing a contour-matched molding 27, and corresponding to the contour of the contour 5 and with a metal and ceramic composite layer 9 to the hot side 3 directed towards.

As explained in connection with FIGS. 1A, 1B, 2A, 2B, a metal layer and a ceramic layer are joined to one another in a material or form-locking manner to form the composite layer. The fittings 27 themselves are screwed as required, glued or welded as shown in connection with the preceding figures, by a welded joint 25 in the context of the manufacturing process. The said joining processes prove to be advantageous, in particular, since they facilitate the assemblability of the shaped pieces 27 and improve their mechanical stability with respect to transient thermal processes.

In order simultaneously to impart a high temperature as well as mechanical resistance to a steam-heated component 10, 20, 30, 40 of a steam turbine plant, the component 10, 20, 30, 40 faces a hot steam space 1 Hot side 3 a on a component body 23 applied cladding 7, which is the contour 5 of the component body 23 adapted. According to the new concept, the cladding 7 has a number of shaped pieces 27, and a shaped piece 27 has a metal and ceramic composite layer 9, which is formed from at least one metal layer 11 and at least one ceramic layer 13. The ceramic layer 13 serves in particular as an insulating layer. The metal layer 11 serves in particular as a support or to protect against abrasion and / or erosion.
