Definitions
- the present invention relates to holding elements and heat shield elements for constructing a buildin to a supporting structure ⁇ saturated heat shield as well as a combustion chamber with a support structure and ⁇ -affixed heat shield.
- Heat shields are used for example in combustion chambers or flame tubes, which may be part of a kiln, a H exertgaska ⁇ nals or a gas turbine and in which a hot medium is generated or performed, are used.
- thermally highly loaded gas turbine combustion chambers are lined with a heat shield to protect against excessive thermal stress.
- the heat shield comprises ⁇ typi cally a number of coverage to a support structure arranged heat shield elements, which shield the wall of the combustion chamber against the hot combustion exhaust gas.
- the gaps between heat shield elements by means of sealing air, ie by means of compressed air flowing through the gaps in the combustion chamber, shielded against ingress of hot gas. If large gaps, which can occur due to axial displacements, are to be taken into account, this increases the need for blocking air, which is necessary to sufficiently block the large gaps.
- sealing air ie by means of compressed air flowing through the gaps in the combustion chamber.
- blocking air which is necessary to sufficiently block the large gaps.
- ceramic heat shield elements in the large column of increased blocking air flow leads to a higher temperature gradient within the heat shield elements.
- the increased temperature gradient leads to increased cracking in the region of the edges of the ceramic heat shield elements, and also moreover, that the cracks are longer than peraturgradienten at a lower ⁇ Tem.
- At least one material recess is present in a portion of a material bar or the groove bottom, which is located in a provided for engagement of a holding element portion of the engagement groove. In this material recess, the projection of a holding element according to the invention can engage.
- the heat shield elements are preferably ceramic heat shield elements, in the case of the retaining elements preferably metallic retaining elements.
- FIG. 1 shows a detail of a heat shield on a support structure in a schematic representation
- FIG. 2 shows a heat shield element fixed to the support structure by means of a retaining element.
- FIG 6 shows a second embodiment of a dung OF INVENTION ⁇ according heat shield element.
- FIG 7 shows a third embodiment of a dung OF INVENTION ⁇ according retaining element.
- FIG 8 shows a third embodiment of a dung OF INVENTION ⁇ according heat shield element.
- FIG 9 shows a fourth exemplary embodiment of a dung OF INVENTION ⁇ according retaining element.
- the heat shield element 100 has a cold side 102 facing the support structure, a hot side 104 facing away from the support structure, and peripheral sides 106, 108 which connect the cold side 102 to the hot side 104.
- the circumferential sides 108 extend in the circumferential direction U of the combustion chamber and the circumferential sides 106 in the axial direction A.
- the circumferential sides 106 are provided with a groove 110, which likewise extends in the axial direction of the combustion chamber extends. In the groove 110 engages a holding portion 152 of the retaining element 150, hereinafter referred to as the holder head, a.
- the holding element 150 is guided in a groove 5 of the support structure 3.
- a widened fixing section engages (in FIG 2 is not shown) of the holding element 150, the so- ⁇ called shoe of the holding element 150, closely embedded to the surface of the support structure 3 tolerated in the pa ⁇ rallel an approximately 10 mm deep groove.
- the groove 5 is designed so that it only has the groove base 7 required for the insertion of the shoe width.
- FIG 9 illustrates ones shown,.
- this holding element in the region of the gripping tab 358 has a hook-shaped projection 362. This is disposed on an edge 359 of the grip tab 358, which extends in the circumferential direction U of the combustion chamber, when the holding member 350 is mounted on the support structure, and is bent in the direction of the transition portion 356.
