Abstract

A device for reducing inter-seal gap in gas turbines. Embodiments of a gas turbine with a first arcuate component adjacent to a second arcuate component; a first slot and a connected second slot on an end of the first arcuate component; a first seal disposed into the first slot and a first adjacent slot on the second arcuate component; a second seal disposed into the second slot and a second adjacent slot on the second arcuate component, leaving a gap between the first seal and the second seal; and a connector coupled to the first seal and the second seal and substantially covering the gap between the first seal and the second seal.

Claims (31)

1. A gas turbine, comprising:

a first arcuate component adjacent to a second arcuate component;

a first slot and a second slot connected to the first slot on an end of the first arcuate component;

a first seal disposed into the first slot and a first adjacent slot on the second arcuate component;

a second seal disposed into the second slot and a second adjacent slot on the second arcuate component, leaving a gap between the first seal and the second seal; and

a connector, wherein the connector is disposed into the first slot and a first adjacent slot and the second slot and the second adjacent slot, is coupled to the first seal and the second seal, and substantially covers the gap between the first seal and the second seal.

2. The gas turbine of claim 1 , wherein the connector includes a flexible material.

3. The gas turbine of claim 1 , wherein the first seal and the second seal include a semi-rigid material.

4. The gas turbine of claim 1 , wherein the connector is coupled to the first seal and the second seal with an adhesive.

5. The gas turbine of claim 1 , wherein the first seal and the second seal each include at least one of metal, a cloth-layer, a cloth-layer assemblage, and a foil-layer assemblage.

6. The gas turbine of claim 1 , wherein the connector includes at least one of metal, a cloth-layer, a cloth-layer assemblage, and a foil-layer assemblage.

7. The gas turbine of claim 1 , wherein the first seal and the second seal and the connector are a unitary continuous material.

8. The gas turbine of claim 1 , wherein the connector is substantially the same width as the first seal and the second seal.

9. The gas turbine of claim 1 , wherein the first arcuate component and second arcuate component are one of an outer shroud, an inner shroud, a nozzle block or a diaphragm.

10. The gas turbine of claim 1 , wherein the connector is coupled to the first seal and the second seal with a plurality of attachments.

11. The gas turbine of claim 10 , wherein each attachment includes at least one of a spot weld or a tack.

12. A gas turbine, comprising:

a turbine including at least one annular arrangement of arcuate components;

a first arcuate component adjacent to a second arcuate component, wherein the first arcuate component and second arcuate component are one of an outer shroud, an inner shroud, a nozzle block or a diaphragm;

a first slot and a second slot connected to the first slot on an end of the first arcuate component;

a first seal disposed into the first slot and a first adjacent slot on the second arcuate component;

a second seal disposed into the second slot and a second adjacent slot on the second arcuate component, leaving a gap between the first seal and the second seal; and

a connector, wherein the connector is disposed into the first slot and a first adiacent slot and the second slot and the second adiacent slot, is coupled to the first seal and the second seal, and substantially covers the gap between the first seal and the second seal.

13. The gas turbine of claim 12 , wherein the connector includes a flexible material.

14. The gas turbine of claim 12 , wherein the first seal and the second seal include a semi-rigid material.

15. The gas turbine of claim 12 , wherein the connector is coupled to the first seal and the second seal with an adhesive.

16. The gas turbine of claim 12 , wherein the first seal and the second seal each include at least one of metal, a cloth-layer, a cloth-layer assemblage, and a foil-layer assemblage.

17. The gas turbine of claim 12 , wherein the connector includes at least one of metal, a cloth-layer, a cloth-layer assemblage, and a foil-layer assemblage.

18. The gas turbine of claim 12 , wherein the first seal and the second seal and the connector are a unitary continuous material.

19. The gas turbine of claim 12 , wherein the connector is coupled to the first seal and the second seal with a plurality of attachments.

20. The gas turbine of claim 19 , wherein each attachment includes at least one of a spot weld or a tack.
