Abstract:
Disclosed herein are a nozzle capable of efficiently atomizing fuel, a combustor, and a gas turbine. The nozzle for the combustor includes a tube assembly including an air passage through which air moves, a main fuel passage disposed inside the air passage so that main fuel moves through the main fuel passage, and a pilot fuel passage disposed inside the main fuel passage so that pilot fuel moves through the pilot fuel passage as well as a nozzle tip configured to eject the pilot fuel and the main fuel, where the nozzle tip includes an injection passage coupled with the pilot fuel passage and a plurality of centrifugal flow chambers disposed outside the injection passage and communicating with the main fuel passage.
