A system for supplying a working fluid to a combustor includes a combustion chamber, a liner that circumferentially surrounds at least a portion of the combustion chamber, and a flow sleeve that circumferentially surrounds at least a portion of the liner. A tube provides fluid communication for the working fluid to flow through the flow sleeve and the liner and into the combustion chamber, and the tube spirals between the flow sleeve and the liner.

1. A system for supplying a working fluid to a combustor, comprising: a. a combustion chamber;b. a liner that circumferentially surrounds at least a portion of the combustion chamber;c. a flow sleeve having an inner sleeve that circumferentially surrounds at least a portion of the liner, an outer sleeve that circumferentially surrounds the inner sleeve and a fuel passage defined by and between the inner and outer sleeves;d. a tube that provides fluid communication for the working fluid to flow through the flow sleeve and the liner and into the combustion chamber, wherein the tube spirals between the flow sleeve and the liner; ande. a plurality of fuel ports circumferentially arranged around an inlet of the tube, wherein each fuel port is in fluid communication with the fuel passage. 2. The system as in claim 1, wherein the tube comprises a tapered end that passes through the liner. 3. The system as in claim 2, wherein the tapered end is asymmetric. 4. The system as in claim 2, wherein the tapered end comprises a first side that intersects the liner at a first acute angle, a second side opposite the first side that intersects the liner at a second angle, and the first acute angle is less than the second angle. 5. The system as in claim 1, wherein the tube comprises an elliptical cross-section having a longitudinal axis. 6. The system as in claim 5, wherein the longitudinal axis of the elliptical cross-section is angled with respect to a longitudinal axis of the combustion chamber as the tube passes through the liner. 7. The system as in claim 1, wherein the tube comprises a tapered end that passes through the liner and an elliptical cross-section having a longitudinal axis. 8. A system for supplying a working fluid to a combustor, comprising: a. a combustion chamber;b. a liner that circumferentially surrounds at least a portion of the combustion chamber;c. a flow sleeve having an inner sleeve that circumferentially surrounds at least a portion of the liner, an outer sleeve that circumferentially surrounds the inner sleeve and a fuel passage defined by and between the inner and outer sleeves;d. a tube that provides fluid communication through the flow sleeve and the liner and into the combustion chamber, wherein the tube comprises a first side that intersects the liner at a first acute angle, a second side opposite the first side that intersects the liner at a second angle, and the first acute angle is less than the second angle; ande. a plurality of fuel ports circumferentially arranged around an inlet of the tube, wherein each fuel port is in fluid communication with the fuel passage. 9. The system as in claim 8, wherein the tube spirals between the flow sleeve and the liner. 10. The system as in claim 8, wherein the tube comprises an elliptical cross-section having a longitudinal axis. 11. The system as in claim 10, wherein the longitudinal axis of the elliptical cross-section is angled with respect to a longitudinal axis of the combustion chamber as the tube passes through the liner. 12. The system as in claim 8, wherein the tube comprises an elliptical cross-section having a longitudinal axis that spirals between the flow sleeve and the liner. 13. A system for supplying a working fluid to a combustor, comprising: a. a combustion chamber;b. a liner that circumferentially surrounds at least a portion of the combustion chamber;c. a flow sleeve having an inner sleeve that circumferentially surrounds at least a portion of the liner, an outer sleeve that circumferentially surrounds the inner sleeve and a fuel passage defined by and between the inner and outer sleeves;d. a tube that provides fluid communication for the working fluid to flow through the flow sleeve and the liner and into the combustion chamber, wherein the tube comprises an elliptical cross-section having a longitudinal axis, and the longitudinal axis of the elliptical cross-section is angled with respect to a longitudinal axis of the combustion chamber as the tube passes through the liner; ande. a plurality of fuel ports circumferentially arranged around an inlet of the tube, wherein each fuel port is in fluid communication with the fuel passage. 14. The system as in claim 13, wherein the tube spirals between the flow sleeve and the liner. 15. The system as in claim 13, wherein the tube comprises a tapered end that passes through the liner. 16. The system as in claim 15, wherein the tapered end comprises a first side that intersects the liner at a first acute angle, a second side opposite the first side that intersects the liner at a second angle, and the first acute angle is less than the second angle.
