Title: COMBUSTION DEVICE AND GAS TURBINE
Abstract:
A combustion device is provided with a nozzle casing that defines an axial channel, and a nozzle disposed inside the axial channel. The nozzle includes: a cylindrical nozzle body extending along the axial channel; a swirler vane projecting radially outwards from the nozzle body with respect to the radial direction of the nozzle body, the swirler vane being configured so as to swirl a fluid flowing in the axial channel; at least one first injection hole which opens on the surface of the swirler vane or the nozzle body; at least one second injection hole which opens on the surface of the swirler vane or the nozzle body; a first fuel channel extending inside the nozzle body and in communication with the at-least-one first injection hole; and a second fuel channel extending inside the nozzle body separately from the first fuel channel, the second fuel channel being in communication with the at-least-one second injection hole.
