A purge system and liquid fuel atomizing system, a system including a purge system and liquid fuel atomizing system, and a method of purging and atomizing are disclosed. The purging involves a first nozzle, a second nozzle, a third nozzle, and a staged compression system having a first stage and a second stage. The first stage is configured to selectively direct a first pressurized fluid stream to the first nozzle and the second nozzle. The second stage is configured to selectively direct a second pressurized fluid stream to the third nozzle.

1. A system, comprising: a gas turbine engine comprising:a first set of nozzles;a second set of nozzles;a third set of nozzles;a combustor;wherein one of the first, second and third sets of nozzles include at least one liquid fuel nozzle, and one of the first, second and third sets of nozzles includ
1. A system, comprising: a gas turbine engine comprising:a first set of nozzles;a second set of nozzles;a third set of nozzles;a combustor;wherein one of the first, second and third sets of nozzles include at least one liquid fuel nozzle, and one of the first, second and third sets of nozzles include at least one gaseous fuel nozzle;a carbon capture system comprising a staged compression system having at least a first stage of compression and a second stage of compression;wherein the first stage of compression is configured to selectively direct a first pressurized fluid stream to purge the first and second sets of nozzles in response to a first operating mode;and wherein the second stage of compression is configured to selectively direct a second pressurized fluid stream to purge the third set of nozzles in response to a second operating mode;wherein the first and second pressurized fluid streams are non-combustible and include CO2 at a concentration greater than the concentration of CO2 in air;wherein the second pressurized fluid stream is greater in pressure than the first pressurized fluid stream. 2. The system of claim 1, further comprising the combustor, wherein the combustor is arranged and disposed to receive liquid fuel from the first set of nozzles and gaseous fuel from the second set of nozzles. 3. The system of claim 1, wherein the first pressurized fluid stream cools the first set of nozzles and the second set of nozzles. 4. The system of claim 1, wherein the second set of nozzles includes a water injection nozzle. 5. The system of claim 1, wherein the first set of nozzles includes a gaseous fuel nozzle. 6. The system of claim 1, wherein the third set of nozzles includes an atomizing nozzle. 7. The system of claim 1, wherein the staged compression system is in fluid communication with one or more valves, the one or more valves being configured to selectively direct the first pressurized fluid stream to the first set of nozzles and the second set of nozzles and selectively direct the second pressurized fluid stream to the third set of nozzles. 8. The system of claim 7, further comprising an accumulator to provide continuous pressure supply of a purging fluid in response to compression system failure. 9. The system of claim 8, wherein continuous pressure prevents backflow of combustion products from the gas turbine in fluid communication with the combustor, wherein the combustor is arranged and disposed to receive gaseous fuel from the first set of nozzles and liquid fuel from the second set of nozzles. 10. The system of claim 9, wherein the first pressurized fluid stream is directed through the accumulator. 11. The system of claim 1, wherein the first pressurized fluid stream consists essentially of CO2. 12. The system of claim 11, wherein a predetermined pressure of the first pressurized fluid stream is the critical pressure of the fluid. 13. The system of claim 1, wherein the first pressurized fluid stream consists of CO2. 14. The system of claim 1, wherein the first stage of compression and the second stage of compression are separated by a staged compressor and an intercooler. 15. A system, comprising: a gas turbine engine comprising:a first set of nozzles;a second set of nozzles;a third set of nozzles;a combustor; andwherein one of the first, second and third sets of nozzles include at least one liquid fuel nozzle and one of the first, second and third sets of nozzles include at least one gaseous fuel nozzle;a carbon capture system having a staged compression system, the staged compression system having a first stage of compression and a second stage of compression;wherein the first stage of compression is configured to receive a first CO2 stream from the carbon capture system and direct the first CO2 stream to the first and second sets of nozzles for purging;wherein the second stage of compression is configured to receive a second CO2 stream and direct the second CO2 stream to the third set of nozzles for purging;wherein the first and second CO2 streams are at a concentration greater than the concentration of CO2 in air;wherein the second CO2 stream is greater in pressure than the first CO2 stream. 16. The system of claim 15, further comprising the gas turbine in fluid communication with the combustor, wherein the combustor is arranged and disposed to receive gaseous fuel from the first set of nozzles and liquid fuel from the second set of nozzles. 17. A system, comprising: a gas turbine engine comprising:a first set of nozzles;a second set of nozzles;a third set of nozzles;a combustor;wherein one of the first, second and third sets of nozzles include at least one liquid fuel nozzle and one of the first, second and third sets of nozzles include at least one gaseous fuel nozzle;a carbon capture system comprising a staged compression system having at least a first stage of compression and a second stage of compression;wherein the carbon capture system is configured to selectively direct a first pressurized fluid stream to purge the first set of nozzles and the second set of nozzles from the first stage of compression;wherein the carbon capture system is configured to selectively direct a second pressurized fluid stream to purge the third set of nozzles from the second stage of compression;wherein the first and second pressurized fluid streams are non-combustible and include CO2 at a concentration greater than the concentration of CO2 in air; andwherein the second pressurized fluid stream is greater in pressure than the first pressurized fluid stream. 18. The system of claim 17, further comprising the gas turbine in fluid communication with the combustor, wherein the combustor is arranged and disposed to receive gaseous fuel from the first set of nozzles and liquid fuel from the second set of nozzles.
