FUEL NOZZLE, COMBUSTOR EQUIPPED WITH FUEL NOZZLE, AND GAS TURBINE EQUIPPED WITH FUEL NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a fuel nozzle capable of suppressing an increase in pressure variation near a fuel nozzle hole, a combustor equipped with same, and a gas turbine equipped with same.;SOLUTION: In a fuel nozzle 20 comprising: a fuel nozzle hole 23; a channel 27 for supplying a fuel to the fuel nozzle hole 23; an outer cylinder 24 having the fuel nozzle hole 23 provided in an outer circumference of a lower end of the outer cylinder 24; and an inner cylinder 25 stored in the lower end of the outer cylinder 24, the channel 27 is formed between the outer cylinder 24 and the inner cylinder 25 and has a length such that a pressure variation propagated from the fuel nozzle hole 23 can be suppressed by pressure loss by providing the channel 27 on the lower end of the outer cylinder 24.;COPYRIGHT: (C)2015,JPO&INPIT
