Abstract

A combustion chamber tile of a gas turbine includes a bolt for mounting the combustion chamber tile on a combustion chamber wall, with the combustion chamber tile being designed substantially plate-like and having on one side at least one mounting element, on which the bolt, which is provided as a separate component, is positively anchored.

First claim

What is claimed is:

1. A combustion chamber tile of a gas turbine comprising:
a plate body having a combustion side facing in a combustion chamber interior direction and a combustion chamber wall side facing in a combustion chamber wall direction;
a mounting element positioned on the combustion chamber wall side of the plate body and having an exposed outer side facing in the combustion chamber wall direction, wherein the mounting element has a first relative height at the exposed outer side of the mounting element measured with respect to a reference point on the combustion chamber wall side of the plate body;
a separate bolt anchored to the mounting element, the separate bolt for mounting the combustion chamber tile on a combustion chamber wall;
wherein the separate bolt includes a mounting section at an end area of the separate bolt, the mounting section arranged at a right angle to a bolt axis of the separate bolt such that the separate bolt is L-shaped or T-shaped, the mounting section positioned in a recess of the mounting element;
a support for supporting the plate body and spacing the plate body from against the combustion chamber wall, the support extending from the plate body in the combustion chamber wall direction and having an exposed outer side facing in the combustion chamber wall direction for engaging the combustion chamber wall, wherein the support has a second relative height at the exposed outer side of the support, measured with respect to the reference point;
wherein the first relative height of the mounting element is smaller than the second relative height of the support.

2. The combustion chamber tile in accordance with claim 1 , wherein the separate bolt with the mounting section is insertable into the mounting element in a direction of the bolt axis and rotatable about the bolt axis by a given angular range.

3. The combustion chamber tile in accordance with claim 2 , wherein the combustion chamber tile includes a plurality of mounting elements, with recesses of the mounting elements being open towards different directions.

4. The combustion chamber tile in accordance with claim 2 , wherein the mounting element includes effusion cooling holes.

5. The combustion chamber tile in accordance with claim 2 , wherein the mounting section is accommodated in the mounting element with a clearance.

6. The combustion chamber tile in accordance with claim 1 , wherein the separate bolt with the mounting section is insertable into the recess in a direction perpendicular to the bolt axis.

7. The combustion chamber tile in accordance with claim 6 , wherein the combustion chamber tile includes a plurality of mounting elements, with recesses of the mounting elements being open towards different directions.

8. The combustion chamber tile in accordance with claim 6 , wherein the mounting element includes effusion cooling holes.

9. The combustion chamber tile in accordance with claim 6 , wherein the mounting section is accommodated in the mounting element with a clearance.

10. The combustion chamber tile in accordance with claim 6 , wherein the mounting section is plate shaped or bar shaped.

11. The combustion chamber tile in accordance with claim 6 , wherein the separate bolt is a threaded bolt.

12. The combustion chamber tile in accordance with claim 6 , wherein the separate bolt and the combustion chamber tile are made from different materials.

13. The combustion chamber tile in accordance with claim 6 , wherein the mounting section is accommodated in the mounting element without a clearance.

14. The combustion chamber tile in accordance with claim 1 , wherein the combustion chamber tile includes a plurality of mounting elements, with recesses of the mounting elements being open towards different directions.

15. The combustion chamber tile in accordance with claim 1 , wherein the mounting element includes effusion cooling holes.

16. The combustion chamber tile in accordance with claim 1 , wherein the mounting section is accommodated in the mounting element with a clearance.

17. The combustion chamber tile in accordance with claim 1 , wherein the mounting section is plate shaped or bar shaped.

18. The combustion chamber tile in accordance with claim 1 , wherein the separate bolt is a threaded bolt.

19. The combustion chamber tile in accordance with claim 1 , wherein the separate bolt and the combustion chamber tile are made from different materials.

20. The combustion chamber tile in accordance with claim 1 , wherein the mounting section is accommodated in the mounting element without a clearance.
