Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and device for reducing exhaust emission of gas turbine engine. SOLUTION: A fuel nozzle 50 for the gas turbine engine 10 comprises a first jet circulation passage 82 that includes an annular delivery opening 94 and jets liquid fuel into a gas turbine engine on the downstream side of the nozzle, a second jet circulation passage 84 aligned substantially concentrically with the first jet circulation passage, and a third jet circulation passage 86 aligned substantially concentrically with the first jet circulation passage. The second jet circulation passage is disposed between the second jet circulation passage and the third jet circulation passage, one of the second and third jet circulation passages jets water into the gas turbine engine on the downstream side of the nozzle, and one of the second and third jet circulation passages includes an annular delivery opening 132.
