Abstract

A segmented annular combustion system includes integrated combustor nozzles, each of which has a fuel injection panel disposed radially between an inner liner segment and an outer liner segment. An aft end portion of the fuel injection panel defines a turbine nozzle. One or more hook plates attached to the outer surfaces of the liner segments are used to mount the integrated combustor nozzle to an inner mounting ring or an outer mounting ring. A mounting strut or mounting tenon(s) attached to the liner segments may also be employed.

Claims

1. A system for mounting integrated combustor nozzles in a segmented annular combustion system, comprising:

an integrated combustor nozzle comprising an inner liner segment, an outer liner segment radially spaced from the inner liner segment, a mounting strut attached to the outer liner segment, and a fuel injection panel that extends radially between the inner liner segment and the outer liner segment, the fuel injection panel including a forward end portion and an aft end portion, the aft end portion defining a turbine nozzle; and

at least one hook plate, wherein the at least one hook plate comprises at least one of an inner hook plate connected to the inner liner segment and an outer hook plate connected to the outer liner segment.

2. The system as in claim 1, further comprising an outer mounting ring, wherein the mounting strut is connected to the outer mounting ring.

3. The system as in claim 1, further comprising an outer mounting ring, wherein the at least one hook plate comprises the outer hook plate, the outer hook plate being coupled to the outer mounting ring.

4. The system as in claim 1, further comprising an inner mounting ring, wherein the at least one hook plate comprises the inner hook plate, the inner hook plate being coupled to the inner mounting ring.

5. The system as in claim 1, further comprising an outer double bellows seal, wherein the outer double bellows seal extends between an outer mounting ring and the outer liner segment proximate to the turbine nozzle of the fuel injection panel.

6. The system as in claim 5, wherein a first end portion of the outer double bellows seal is sealed against the outer mounting ring and a second end portion of the outer double bellows seal is sealed against the outer liner segment.

7. The system as in claim 5, wherein the outer double bellows seal circumferentially spans a plurality of adjacent integrated combustor nozzles.

8. The system as in claim 1, further comprising an inner double bellows seal, wherein the inner double bellows seal extends between an inner mounting ring and the inner liner segment proximate to the turbine nozzle of the fuel injection panel.

9. The system as in claim 8, wherein a first end portion of the inner double bellows seal is sealed against the inner mounting ring and a second end portion of the inner double bellows seal is sealed against the inner liner segment.

10. The system as in claim 8, wherein the inner double bellows seal circumferentially spans a plurality of adjacent integrated combustor nozzles.

11. A system for mounting integrated combustor nozzles in a segmented annular combustion system, comprising:

an integrated combustor nozzle comprising an inner liner segment, an outer liner segment radially spaced from the inner liner segment, and a fuel injection panel that extends radially between the inner liner segment and the outer liner segment, the fuel injection panel including a forward end portion and an aft end portion, the aft end portion defining a turbine nozzle; and

at least one hook plate, wherein the at least one hook plate comprises at least one of an inner hook plate connected to the inner liner segment and an outer hook plate connected to the outer liner segment.

12. The system as in claim 11, further comprising an outer mounting ring, wherein the at least one hook plate comprises the outer hook plate, the outer hook plate being coupled to the outer mounting ring.

13. The system as in claim 11, further comprising an inner mounting ring, wherein the at least one hook plate comprises the inner hook plate, the inner hook plate being coupled to the inner mounting ring.

14. The system as in claim 11, wherein the at least one hook plate comprises both the inner hook plate connected to the inner liner segment and the outer hook plate connected to the outer liner segment.

15. The system as in claim 14, wherein the inner hook plate and the outer hook plate extend in opposite axial directions.

16. The system as in claim 11, wherein the integrated combustor nozzle further comprises a mounting tenon disposed along an outer surface of the inner liner segment.

17. The system as in claim 11, wherein the integrated combustor nozzle further comprises a mounting tenon disposed along an outer surface of the outer liner segment.

18. The system as in claim 11, wherein the integrated combustor nozzle further comprises a mounting tenon disposed along an outer surface of at least one of the outer liner segment and an outer surface of the inner liner segment, wherein the mounting tenon has a dovetail or fir tree shape.

19. The system as in claim 11, wherein the integrated combustor nozzle further comprises a mounting tenon disposed along an outer surface of the inner liner segment, and the system further comprises an inner forward ring defining a slot, the mounting tenon being disposed within the slot.

20. The system as in claim 19, further comprising a damper disposed within the slot between walls of the slot and the mounting tenon.
