FUEL INJECTION NOZZLE OF GAS TURBINE ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a fuel injection nozzle of a gas turbine engine capable of performing efficient combustion having improved thermal stability with low-calorie gas as a fuel. SOLUTION: The fuel injection nozzle 28 that is fitted to the top of a combustor 20 in the gas turbine engine while a number of nozzle holes 34 for injecting fuel gas are open concentrically toward the inside of the cylinder of the combustor 20 at the periphery, the injection hole 34 for each fuel gas is set to be in a swirler injection hole type in the inverse direction for generating a swirling flow in the inverse direction to the inclination direction of a swirler 36 for injecting compressed air that is open at the top around the injection nozzle 28 and generates a swirl flow inside the combustor.
