A system for supplying a working fluid to a combustor includes a fuel nozzle, a combustion chamber downstream from the fuel nozzle, and a flow sleeve that circumferentially surrounds the combustion chamber. A plurality of fuel injectors are circumferentially arranged around the flow sleeve to provide fluid communication through the flow sleeve and into the combustion chamber. A separate cap for each fuel injector defines a separate volume around a different fuel injector outside of the flow sleeve, and a fluid passage through the flow sleeve and into each separate volume provides fluid communication through the flow sleeve and into each separate volume.

1. A system for supplying a working fluid to a combustor, comprising: a. a fuel nozzle;b. a combustion chamber downstream from the fuel nozzle;c. a flow sleeve that circumferentially surrounds the combustion chamber;d. a plurality of fuel injectors circumferentially arranged around the flow sleeve,
1. A system for supplying a working fluid to a combustor, comprising: a. a fuel nozzle;b. a combustion chamber downstream from the fuel nozzle;c. a flow sleeve that circumferentially surrounds the combustion chamber;d. a plurality of fuel injectors circumferentially arranged around the flow sleeve, wherein the plurality of fuel injectors provide fluid communication through the flow sleeve and into the combustion chamber;e. a separate cap for each fuel injector, wherein each separate cap defines a separate volume around a different fuel injector outside of the flow sleeve; andf. a fluid passage through the flow sleeve and into each separate volume, wherein each fluid passage provides fluid communication through the flow sleeve and into each separate volume. 2. The system as in claim 1, wherein each separate cap is connected to the flow sleeve. 3. The system as in claim 1, wherein each separate cap is connected to the flow sleeve around a circumference of the different fuel injector. 4. The system as in claim 1, further comprising a flow passage through each separate cap. 5. The system as in claim 1, wherein each fluid passage through the flow sleeve is upstream from each different fuel injector. 6. The system as in claim 1, further comprising a plurality of fluid passages through the flow sleeve and into each separate volume. 7. The system as in claim 6, wherein the plurality of fluid passages through the flow sleeve circumferentially surround each different fuel injector. 8. The system as in claim 1, further comprising a fuel passage through the flow sleeve in fluid communication with each fuel injector. 9. A system for supplying a working fluid to a combustor, comprising: a. a combustion chamber;b. a liner that circumferentially surrounds the combustion chamber;c. a flow sleeve that circumferentially surrounds the liner;d. a plurality of fuel injectors circumferentially arranged around the flow sleeve, wherein the plurality of fuel injectors provide fluid communication through the flow sleeve and the liner into the combustion chamber;e. a separate cap for each fuel injector, wherein each separate cap defines a separate volume around a different fuel injector outside of the flow sleeve; andf. a fluid passage through the flow sleeve and into each separate volume, wherein each fluid passage provides fluid communication through the flow sleeve and into each separate volume. 10. The system as in claim 9, wherein each separate cap is connected to the flow sleeve. 11. The system as in claim 9, wherein each separate cap is connected to the flow sleeve around a circumference of the different fuel injector. 12. The system as in claim 9, further comprising a flow passage through each separate cap. 13. The system as in claim 9, wherein each fluid passage through the flow sleeve is upstream from each different fuel injector. 14. The system as in claim 9, further comprising a plurality of fluid passages through the flow sleeve and into each separate volume. 15. The system as in claim 14, wherein the plurality of fluid passages through the flow sleeve circumferentially surround each different fuel injector. 16. A system for supplying a working fluid to a combustor, comprising: a. a fuel nozzle;b. a combustion chamber downstream from the fuel nozzle;c. a liner that circumferentially surrounds the combustion chamber;d. a plurality of fuel injectors circumferentially arranged around the liner, wherein the plurality of fuel injectors provide fluid communication through the liner and into the combustion chamber;e. an annular passage that circumferentially surrounds the liner;f. a separate cap for each fuel injector, wherein each separate cap defines a separate volume around a different fuel injector outside of the liner; andg. a fluid passage that connects the annular passage to each separate volume, wherein each fluid passage provides fluid communication from the annular passage into each separate volume. 17. The system as in claim 16, wherein the annular passage is substantially coextensive with the liner. 18. The system as in claim 16, further comprising a flow passage through each separate cap, wherein each flow passage provides fluid communication out of each separate volume through each separate cap. 19. The system as in claim 16, wherein each fluid passage is upstream from each different fuel injector. 20. The system as in claim 16, further comprising a plurality of fluid passages that connect the annular passage to each separate volume.
