초록

A dual fuel injector for injecting liquid and/or gaseous fuel into a gas turbine engine includes a plurality of hollow spoke members for injecting gaseous fuel that are located upstream of a plurality of main air swirling vanes that are in turn upstream of a plurality of air-blast atomizers for injecting main liquid fuel. A pilot fueling arrangement is provided that is capable of starting the gas turbine engine using either gaseous or liquid fuel. The injector includes a labyrinth-shaped cooling passage capable of providing cooling air to cylindrical wal...
