Definitions
- the invention relates to a ceramic lining according to the preamble of Claim 1.
- Such linings are used in particular as inner wall insulation of metallic combustion chambers.
- a ceramic lining of the type mentioned is known from DE 195 02 730 A1.
- the lining there aims at an uncooled removable lining a combustion chamber with ceramic elements, which the high mechanical and thermal stresses in a commercial withstands the highly loaded combustion chamber.
- the lining consists of at least one wall plate made of high temperature resistant Structural ceramics with at least one through opening and one fastener per opening.
- the fastener is with his foot in a metallic one attached to the metallic supporting wall Holding device attached. The head of the fastener rests in the opening the wall plate. Between the metallic wall and the ceramic An insulating layer is arranged on the wall plate.
- the fastener consists of high temperature-resistant structural ceramics and is resilient tied the holding device.
- the fastening element has a shape that is optimized from a thermal point of view, preferably one Arching in the middle of the head, a rounded head and rounded Cross-sectional transitions with large radii from the head to the shaft and from the shaft to the foot. This ensures that the mechanically and thermally conditioned Loads cause only low voltages.
- the seat of the bolt on the tile is a ball / ball seat executed.
- This, among other things a bending moment-free pendulum movement of the bolt to ensure, as a result of manufacturing and assembly inaccuracies and / or also due to operational displacements of the components can get into an imbalance.
- the ball diameter of the Bolzens exactly corresponds to that of the tile, one is created on the contact surface negligible Hertzian pressure.
- the advantage of the invention is particularly in the simplicity of the measure see. While maintaining the angular mobility of the bolt, the Solution through cost-effective manufacturing.
- FIG. 1 shows a partial longitudinal section of the lining according to the invention for a gas turbine combustion chamber.
- An insulation layer 2 is applied to the metallic support wall 1 of the combustion chamber.
- This preferably consists of ceramic fiber material.
- the wall plates 3 and the insulation layer 2 are fastened to the metallic supporting wall 1 with the aid of fastening elements 4, which are each arranged in a metallic holding device 5, which will be described in detail later.
- these fastening elements 4 also consist of high-temperature-resistant structural ceramics.
- the outer shape and the dimensions of the wall panels 3 can easily can be adapted to the geometry of the room to be lined and are in not predetermined in any way.
- Fig. 2 shows a possible shape of the wall panels 3.
- You have in this embodiment a hexagonal outer contour.
- the Thickness d of the wall plate 3 results on the one hand from the required mechanical Stability and, on the other hand, from minimizing thermal stresses due to temperature gradients in the component. In the simplest case, too a square outline can be applied to flat or just light lining curved combustion chambers.
- wall plates 3 with one rectangular outer contour can be used.
- a fastener 4 which is a bolt here, the head, shaft and foot exists, arranged.
- a plurality of openings 6 in each wall plate 3 be present.
- the contact surface between the head 20 arranged in the opening 6 of the Fastening element 4 and the wall plate 3 is optimal according to the invention Executed in a manner even at low angular positions of the bolt ensure clear touch.
- the head 20 is spherical Provide bearing surface with its roundness 21 on a straight in cross section Contact surface 22 abuts. This straight section is the opening 6 adjoining wall of the wall plate 3. With this measure, the easily determine the area in which line contact occurs, as this is usually the case expected tolerances are known.
- the Hertzian pressure in the against each other pressed surfaces - here convex surface against flat surface significantly lower than with the known ball / ball seats and can be easily determine analytically. Nevertheless, a good sealing effect is also achieved here, if this is desired at all.
- the cavity is between the shaft of the fastener 4 and the insulation layer 2 by a divided sleeve 15 made of solidified preformed insulation material filled.
- the metallic holding device 5 consists of a longitudinally divided Threaded sleeve 7, which includes the foot of the fastener.
- a threaded nut 9 is arranged on the external thread of the threaded sleeve 7, which are used to set the clamping force, as explained below can.
- the nut 9 holds the two halves of the threaded sleeve 7 together.
- the mutual positioning of the two threaded sleeve halves can be replaced by additional construction elements, e.g. the bolts, ensured become.
- a square 10 serves to split the sleeve when tightening the threaded nut 9 hold. Positions 7 and 10 are part of the split sleeve.
- the metallic holding device 5 consists of one in the metallic Carrying wall 1 embedded guide ring 11, a one-piece guide sleeve 12 for the fastener 4 and from between the guide sleeve 12 and the Guide ring 11 arranged spring elements 13.
- the spring 13 is, for example, as shown in Fig. 1, a plate spring. Due to the resilient Connection of the ceramic structure to the metallic holding device achieved that relative thermal expansions between the metallic and ceramic components or deformations of the insulation layer 2 ("setting") due to mechanical stresses, for example pulsations in the combustion chamber, be recorded without excessive voltages on the contact surfaces be induced in the ceramic component. Over a certain travel the clamping (via the screwed on the external thread of the sleeve 7 Threaded nut 9 adjustable) are almost constant clamping forces guaranteed.
- the invention is not based on the embodiment described limited.
- the head In deviation from the spherical shape of the head and the conical shape of the contact surface in the case of linearly extended seats (perpendicular to the plane of the drawing) the head also circular and the contact surface trapezoidal his. Otherwise, the proposed introduction of force can be advantageous Attachment of all possible brittle components should be mentioned, if force can be applied using a ball / cone seat.
