Definitions
- the invention relates to a gas turbine blade with a Airfoil and one adjacent to the airfoil Platform area for delimiting a hot gas duct Gas turbine in which the gas turbine blade can be installed.
- the invention also relates to a gas turbine having one Gas turbine blade.
- a gas turbine blade emerges from DE 26 28 807 A.
- the gas turbine blade is directed along a blade axis and has an airfoil along the airfoil axis and a platform area. Stretches in the platform area a platform from the airfoil extends transversely to the airfoil axis radially outward.
- Such a platform forms one Part of a flow channel for a working fluid, which flows through a gas turbine into which the turbine blade is installed is. In a gas turbine, this flow channel occurs very high temperatures. This becomes the hot gas exposed surface of the platform is subjected to high thermal loads. This requires cooling the platform. For cooling the platform is in front of the side facing away from the hot gas a perforated wall element is arranged on the platform.
- cooling air for components to be cooled branched off from a compressor that compresses air for generates the combustion in the gas turbine.
- cooling air is the amount of air that can be supplied to the combustion reduced. This will make the gas turbine more efficient reduced. Accordingly, one tries to reduce the consumption of cooling air to be kept as low as possible with a gas turbine.
- the object of the invention is to provide a gas turbine blade, which has a particularly low requirement for cooling air.
- Another object of the invention is to provide a Gas turbine with a particularly low requirement for cooling air.
- the object directed to a gas turbine blade is achieved according to the invention solved by specifying a gas turbine blade with an airfoil and one adjacent to the airfoil Platform area for delimiting a hot gas duct a gas turbine in which the gas turbine blade can be installed is, the platform area having a metal platform, on which a ceramic cover by means of a mechanical Fasteners attached attached.
- the completely new path is taken platform of a gas turbine blade delimiting the hot gas duct with a mechanically attached, ceramic cover to provide.
- a ceramic cover With such a ceramic cover the metal platform becomes effective before the hot gas duct shielded from flowing hot gas. Accordingly, the Metal platform can be cooled significantly less. In certain circumstances can even rely entirely on cooling the metal platform to be dispensed with. This has a significantly reduced need of cooling air, which in turn increases the efficiency of a Gas turbine increases, in which the gas turbine blade is installed is.
- the gas turbine blade of the proposed type is also also very easy to manufacture, as a conventional gas turbine blade only with regard to their radial dimensioning something needs to be changed so that the ceramic cover blends into the hot gas duct.
- the gas turbine blade can otherwise be made as usual, especially by pouring.
- the ceramic cover can be used later by means of the mechanical fastener on the Metal platform to be placed and attached.
- the task aimed at a gas turbine solved by specifying a gas turbine with a gas turbine blade according to one of the versions described above.
- the gas turbine blade is preferably in the axial direction a flow channel of the gas turbine between two blades arranged, with the second ceramic cover extends just as far in the axial direction that it does not is brushed by one of the blades. This will certainly prevents the ceramic cover from going through each here adjacent blades rotating past it is damaged by rubbing.
- FIG. 1 schematically shows a gas turbine 1.
- the gas turbine 1 has a compressor 3, one in series Combustion chamber 5 and a turbine part 7.
- the turbine part 7 has a hot gas channel 9.
- In the hot gas channel 9 are Guide vanes 11 arranged and with a housing 8 of the turbine part 7 connected.
- Guide vanes 11 arranged and with a housing 8 of the turbine part 7 connected.
- Along the hot gas channel 9 are in alternating the hot gas duct 9 with the guide vanes 11 Blades 13 arranged with a gas turbine rotor 15 are connected.
- air is in the Compressor 3 compresses and fed to the combustion chamber 5. There it is burned with the addition of fuel.
- the emerging hot exhaust gas 17 then flows through the hot gas duct 9 and moves the gas turbine rotor 15 at one Action on the blades 13 in rotation.
- FIG. 2 shows a section of a hot gas duct 9 a Gas turbine 1.
- Hot gas 17 entering the combustion chamber 17 is in the hot gas channel 9 via a first guide vane 11a initiated.
- the first guide vane 11a is not part of one further illustrated first guide vane ring.
- the first The guide vane 11a follows in the flow direction of the hot gas 17 a first blade 13a.
- the first blade 13a a second guide vane follows in the flow direction of the hot gas 17 11b.
- the second guide vane 11b follows in the direction of flow of the hot gas 17, a second blade 13b. Further blade stages can follow in the hot gas duct 9.
- the first guide vane 11a is over an attachment area 21a connected to the housing 8 of the gas turbine 1. At the attachment area 21a closes a platform area 22 with a metal platform 23a.
- the metal platform 23a has a surface 25a facing the hot gas duct 9.
- a ceramic cover 27a lies on the surface 25a on. The attachment of the ceramic cover 27a becomes later explained with reference to Figure 4.
- the second guide vane 11b is in an analogous manner over its Fastening area 21b connected to the housing 8 and has also a ceramic cover on its metal platform 23b 27b.
- the second guide vane 11b is adjacent on the ceramic cover 27b through the hot gas channel 9 Blade 24b on.
- the airfoil 24b is on the radially inner side by a second ceramic Cover 47 limited, which on the hot gas channel 9th facing side 48 of a second metal platform 41, which is assigned to a second platform area 42.
- the second metal platform 41 borders on an inner ring hook 43 on, which carries an inner ring 45.
- an analogous way is also the radially inner side of the first guide vane 11a configured.
- the ceramic cover 47 has an axial length L, which is just dimensioned so that the adjacent blades Do not touch 13a, 13b. This rules out that the rotating blades 13a, 13b the ceramic cover 47 damage.
- the ceramic covers 27a, 27b, 47 consist of mullite and also have a sealing outer sealing layer 50 that prevents detachment of solid particles. Such Solid particles could otherwise be an eroding one Effect on the gas turbine blades arranged in the hot gas duct 9 11, 13 have.
- Each ceramic cover 27a, 27b, 47 also has an integral mat 52, which is in the ceramic Base body is poured. Through this mat prevents a breakage in a of the ceramic covers 27a, 27b, 47 fragments in the Arrive hot gas channel 9 and there gas turbine blades 11, 13th to damage. The fragments are separated by the mat 52 in one Held together. The damaged ceramic cover can be exchanged on occasion.
- FIG. 3 shows a gas turbine guide vane 11.
- the gas turbine guide vane 11 corresponds to the gas turbine guide vane 11b from Figure 2.
- the structure of the ceramic is shown in more detail Cover 27. This consists of two halves 27d, 27s. there one half 27d borders on a pressure side 63 of the airfoil 24 on. The second half 27s borders on a suction side 61 of the airfoil 24.
- the ceramic cover 27 has on its narrow sides a circumferential one of these narrow sides Longitudinal groove 65 on.
- the second ceramic cover 47 is in divides two halves 47d, 47s and also has one circumferential groove 65.
- the fastening area 21 corresponds the fastening area 21b of FIG. 2.
