Definitions
- the invention relates to a ceramic lining for thermally highly stressed Walls of combustion chambers according to the preamble of patent claim 1.
- Such linings are used in particular as inner wall insulation of metallic combustion chambers, for example for gas turbines.
- Combustion chamber walls can be made of ceramic with polygonal surface elements Material or be designed from metal. The number of corners of these elements is usually 3 to 4. However, hexagonal surface elements are also known. These surface elements have the structure of a plate and are included attached to the metal support structure with a separate bolt.
- a ceramic lining Combustion chamber known, which consists of at least one wall plate made of high temperature resistant Structural ceramics, also called monolithic ceramics, with at least a through opening and one fastener per Opening exists.
- the fastener is with its foot in one on the attached metallic support wall attached metallic holding device, the head of the fastener resting in the opening of the wall plate.
- the fastener is also made of high temperature resistant Structural ceramics and is resiliently connected to the holding device.
- Between the metallic wall and the ceramic wall plate is an insulation layer made of fiber ceramic.
- the lining is non-destructive is removable and can therefore be used several times.
- the combustion chamber must have a ceramic design also the insulation layer on the side facing away from the hot gas Plates are running. Due to the generally porous structure of the insulation material the insulation plates become very sensitive to vibrations, which can break the parts. In addition, brackets for the Isolation are provided.
- the hot gas-bearing combustion chamber bricks in plate form are very good sensitive to vibrations and damage from Foreign parts because the plates are very thin and fragile.
- a combustion chamber with a ceramic lining is known from EP-A-658 724, whose ceramic elements are designed as trapezoids, which lie against each other without gaps are attached radially to the supporting wall and with a center in the Base area of the trapezoidal holding means, for example bolts, are attached to the inside of the supporting wall.
- a disadvantage of this state of the Technology is that on the one hand no additional insulation is provided and on the other hand, due to the trapezoidal shape, rugged cross-sectional transitions between the trapezoid and the holding means exist, which leads to large temperature gradients with associated disadvantages.
- the invention tries to avoid all of these disadvantages. You have the task to develop a ceramic lining for combustion chambers, which which is insensitive to vibrations and large temperature gradients is easy to manufacture, and in which no additional brackets for the Insulations are needed.
- the advantages of the invention are that due to the volume Execution of the ceramic elements achieved a functionally favorable shape becomes. Large hot surfaces of the ceramic elements go continuously in the retaining bolt, so that a constant heat dissipation from the hot Surface in the (cooled) bolts. This will make abrupt cross-sectional transitions that have an unfavorable effect on the stresses in the component would be avoided. Thanks to the integrated retaining bolt, the ceramic ones Elements insensitive to vibrations and temperature gradients, see above that they don't break. In addition, the elements shaped in this way are easy to manufacture. Due to their all-round formability when pressing the blanks, a good degree of compaction can be achieved.
- the cavities that of the ceramic elements with their combustion chamber, d. H. the hot gas side, facing surfaces are formed, are filled with air. This is a very inexpensive variant, because cheap air is used as insulation material.
- the ceramic elements are triangular Base, preferably have a tetrahedral shape. This form is production engineering most inexpensive to manufacture and due to the compact shape of the ceramic elements a good degree of compaction is achieved.
- the ceramic elements with the insulating bodies are advantageous by means of elastic elements, preferably disc springs, cylinder compression springs or corrugated sheets, pressed against the metallic support structure, or the insulation body are pressed against the ceramic elements by means of elastic elements.
- elastic elements preferably disc springs, cylinder compression springs or corrugated sheets, pressed against the metallic support structure, or the insulation body are pressed against the ceramic elements by means of elastic elements.
- the latter is also achieved with an elastically mounted retaining bolt. Due to the resilient Connection of the ceramic structure or the insulation material are the thermal strains between the various components as well as the deformation of the insulation material due to mechanical stress added.
- Fig. 1 shows a perspective view of several ceramic arranged side by side Elements 1 of a ceramic lining not shown Gas turbine combustor.
- a retaining bolt 3 is arranged, which in the tetrahedron is integrated.
- Each ceramic element 1 thus consists of the Tetrahedron including the retaining bolt 3.
- the tetrahedron shape is production-related attractively priced.
- Fig. 2 shows a section along the line II-II in Fig. 1. From Fig. 2 it can be seen that the ceramic elements 1 are each fastened with their retaining bolt 3 to the metal support wall 4 of the combustion chamber. The spaces between the supporting wall 4 and the ceramic elements 1 are filled with insulation material 5. In the simplest case, 5 air can be used as insulation material.
- insulating bodies 5 made of, for example, Al 2 O 3 , ZrO 2 , foams or alloys of both oxides, and reticular ceramics made of both oxides or alloys, and insulating stones made of oxide ceramics, in particular of the oxides mentioned, have a better insulating effect.
- FIG. 3 shows a perspective view of the arrangement of insulation bodies 5 in the cavities between the ceramic elements 1. Between the insulation parts 5 and the ceramic elements 1 there is a positive connection. This eliminates the need for separate brackets for insulation.
- FIG. 4 shows variants of how the insulation 5 can be connected elastically can. It is shown that between the metallic support structure 4 and the Isolation 5 elastic elements 6 are arranged, which the insulation 5 against press the ceramic elements 1 and thus prevent cooling air leaks as well cause vibration damping.
- the elastic elements 6 can doing z.
- Fig. 4 also shows two possible ones Fixing options for the combustion chamber brick (ceramic element 1) on the supporting wall 4. In the left part of FIG. 4 it is shown that the holding bolt 3 is provided with a thread 9 onto which a nut 10 is screwed while in the right part of Fig. 4, the attachment of the retaining bolt 3 and thus the ceramic element 1 on the supporting wall 4 by means of a threaded bushing 11 and a two-part threaded insert 12 is shown.
- the ceramic elements 1 can also be used elastic elements 6 with the insulation 5 are pressed against the supporting structure 4. Then the same advantages are achieved. With suitable insulation material the insulation 5 itself can also serve as a spring element 6.
- tetrahedral elements 1 can be used as ceramic Linings, for example, also used pyramid-shaped elements be what a base area 2 with 4 corners (Fig. 5) or 6 corners (Fig. 6).
- the hot gas side facing Base area 2 also with special thermal insulation layers or abrasion-resistant Layers 13 can be provided. This is recommended if lower quality base material is used, so this then a higher thermal and mechanical mechanical stress can withstand.
- Layers 13 are, for example, layers of reticular ones Suitable structures, but also short fiber reinforced layers, spray layers, chemically deposited layers or in electrical fields (electrophoresis) deposited layers as well as sol-gel or from the gas or liquid phase deposited layers.
- the material for the ceramic elements 1 is primarily monolytic ceramic, sintered or reactive, suitable. But fiber-reinforced ceramic is also suitable.
- the invention is not based on the exemplary embodiments just described limited.
- the retaining bolt 3 can also be elastic be stored, or it can ceramic elements 1 as the lining of Combustion chamber used, which is another pyramid-shaped body as described above.
- the ceramic elements 1 can, for. B. convex or have concave curved tetrahedral surfaces, which is advantageous because so that curvatures of the combustion chamber walls can be compensated well.
