PROBLEM TO BE SOLVED: To unify a flow rate of the fuel injected from fuel nozzles without impairing atomizing performance of the fuel nozzles respectively disposed on combustors.;SOLUTION: A main nozzle hole for injecting main fuel has a structure of a circular flow channel in parallel with an axial portion of the fuel nozzle, having a linear portion of a constant cross-sectional area of the circular flow channel, to achieve the challenge. According to this invention, deviation in fuel flow rate can be reduced without impairing atomizing performance of the fuel nozzles disposed in the combustors, and the fuel nozzles of high reliability can be provided.;COPYRIGHT: (C)2007,JPO&INPIT
