A preferred of operating a gas turbine engine having an inlet for receiving a stream of air to be compressed includes providing a first and a second set of interchangeable spray nozzles. Each of the nozzles in the first set is capable of discharging fluid supplied to the nozzle at a first pressure at a first flow rate. Each of the nozzles in the second set is capable of discharging fluid supplied to the nozzle at the first pressure at a flow rate that is different from the first flow rate.

1. A system for introducing a liquid into an inlet structure, the system comprising: a compressor including the inlet structure, the inlet structure configured to direct an inlet airstream into the compressor;a set of nozzle assemblies configured to direct the liquid into the inlet structure, the nozzle assemblies elongate along a central longitudinal axis, each nozzle assembly having a nozzle body;a first set of first spray nozzle tips, each of the first spray nozzle tips comprising an orifice sized to discharge liquid at a first flow rate, and each of the respective first spray nozzle tips configured to be coupled to the nozzle body;a second set of second spray nozzle tips, each of the second spray nozzle tips comprising an orifice sized differently than the orifice of the first set of spray nozzle tips so that each of the second spray nozzle tips discharges liquid at a second flow rate different than the first flow rate, and each of the respective second spray nozzle tips configured to be coupled to the nozzle body;a plurality of spray nozzle tip quick-connect fittings, each spray nozzle tip quick-connect fitting comprising a first portion coupled to a respective nozzle body, and a mating second portion configured to be coupled to a respective one of the spray nozzle tips in the first and second sets of spray nozzle tips, the mating second portion defining an outer surface that is spaced from the central longitudinal axis along a direction that is substantially transverse to the central longitudinal axis, each spray nozzle quick-connect fitting further including a biasing seal member disposed on the outer surface of the mating second portion, the biasing seal member configured to seal an interface defined between the first portion and the mating second portion;whereby the first and second sets of spray nozzle tips are capable of being disconnected from the set of nozzle bodies without breaking any threaded or welded connection;a manifold mounted proximate the inlet structure and configured to direct the liquid to the set of nozzle bodies;a set of mounting bosses associated with the set of nozzle bodies, each mounting boss configured to mount its respective nozzle body onto the inlet structure of the compressor;a plurality of nozzle body quick-connect fittings, each of the nozzle body quick-connect fittings comprising a first portion configured to be coupled to one of the respective nozzle body and a mating second portion configured to be coupled to one of the respective mounting bosses, whereby each nozzle body are configured to be disconnected from its respective mounting boss without breaking any threaded or welded connection;whereby the spray nozzle quick-connect fittings and the nozzle body quick-connect fittings are configured such that the first spray nozzle tips can be readily replaced by the second spray nozzle tips on the same respective nozzle body such that the system can introduce the liquid via the second set of second spray nozzle tips into the inlet structure at the second flow rate. 2. The system of claim 1, further comprising a retainer mounted on each of the mounting bosses, each of the retainers capable of receiving and retaining a corresponding one of the first and second spray nozzle tips, each of the retainers having a through hole formed therein for facilitating discharge of liquid from the corresponding one of the first and second spray nozzle tips through the retainer. 3. The system of claim 1, wherein each of the nozzle body quick-connect fittings comprises a coupler having a plug, and a socket for removably receiving the plug, the socket comprising a body, a plurality of ball bearings disposed in holes formed in the body, and a collar mounted on the body so that the collar is movable between a first position wherein the collar urges the ball bearings into contact with the plug so that the plug is retained by the socket, and a second position wherein the ball bearings can disengage from the plug thereby allowing the plug to be removed from the socket. 4. The system according to claim 1, wherein the compressor is a centrifugal compressor. 5. The system according to claim 1, wherein the compressor forms a portion of a gas turbine engine. 6. The system according to claim 1, wherein the first portion of each of the nozzle body quick-connect fittings is coupled to its respective nozzle body by a compression fitting. 7. The system according to claim 1, wherein the second portion of each of the nozzle body quick-connect fittings is directly coupled to its respective mounting boss by a threaded connection. 8. The system according to claim 2, wherein each of the mounting bosses is substantially hollow, and wherein each of the retainers is mounted within its respective mounting boss. 9. A system for introducing a liquid into an inlet structure, the system comprising: a compressor including the inlet structure, the inlet structure configured to direct an inlet airstream into the compressor;a set of first spray nozzle assemblies configured to be coupled to the inlet structure, each of the first spray nozzle assemblies comprising an orifice having a first cross-sectional dimension such that the orifice is sized to discharge liquid at a first flow rate;a set of second spray nozzle assemblies, each of the second spray nozzle assemblies comprising an orifice having a second cross-sectional dimension that is different than the first cross-sectional dimension such that the orifice is sized to discharge liquid at a second flow rate different than the first flow rate, each of the first and second spray nozzle assemblies elongate along a respective central longitudinal axis;a manifold configured to direct liquid to either one of the set of first spray nozzle assemblies and the set of second spray nozzle assemblies;a plurality of substantially hollow mounting bosses configured to mount either one of the set of first spray nozzle assemblies and the set of second spray nozzle assemblies onto the inlet structure of the compressor;a retainer disposed in each of the mounting bosses, each retainer configured to receive and retain the spray nozzle assembly mounted on the respective mounting boss, each retainer defining a through hole extending therethrough, the throughhole sized to permit formed therein for facilitating discharge of liquid through the retainer;a plurality of quick-connect fittings, each of the quick-connect fittings comprising a first portion coupled to one of the spray nozzle assemblies, and a mating second portion coupled to one of the mounting bosses, the mating second portion defining an outer surface that is spaced from the respective central longitudinal axis along a direction that is substantially transverse to the respective central longitudinal axis, each quick-connect fitting including a biasing seal member disposed on the outer surface of the mating second portion, the biasing seal member configured to seal an interface between the first portion and the mating second portion;wherein each of the spray nozzle assemblies is substantially disposed within its respective mounting boss between one of the quick-connect fittings and one of the retainer. 10. The system according to claim 9, wherein each of the spray nozzle assemblies comprises a nozzle spray tip and a nozzle body, and wherein the first portion of each of the quick-connect fittings is coupled to a nozzle body, and further comprising a plurality of second quick-connect fittings, a first portion of each of the second quick-connect fittings coupled to a nozzle spray tip and a mating second portion of each of the second quick-connect fittings coupled to a nozzle body.
