Abstract
A fuel nozzle includes a main cylinder extending in one direction; an auxiliary cylinder surrounding the main cylinder and defining a fuel passage between the auxiliary cylinder and the main cylinder; a shroud spaced that is apart from the auxiliary cylinder and surrounds the auxiliary cylinder; a swirler vane that is disposed between the auxiliary cylinder and the shroud and defines a fuel cavity communicating with the fuel passage so that fuel flowing in the fuel passage flows into the fuel cavity; and a fuel flow guide disposed inside the fuel cavity to guide fuel that flows from the fuel passage and enters the fuel cavity and to distribute the guided fuel in the fuel cavity. A fuel aperture is formed in the swirler vane to communicate with the fuel passage and the fuel cavity so that the fuel flows into the fuel cavity via the fuel aperture.
