Fuel injector for combustion chamber of gas turbine, has annular main body, fluid circuit which is partially extended through main body, and axially extended inner body which extends in inner side of main body

摘要

The fuel injector (68) has an annular main body (72), a fluid circuit (94) which is partially extended through the main body, and an axially extended inner body which extends in the inner side of the main body. An inner chamber (90) is defined in the inner side of the inner body, where the inner chamber stand in fluid transmission connection with the fluid circuit. A retractable igniter (70) extends from the inner chamber to the outside in a linear manner, if the fluid circuit is pressurized. Independent claims are included for the following: (1) a combustion chamber with a fuel nozzle; and (2) a gas turbine with a compressor section.
