Abstract

A combustor nozzle (1220) comprises a plurality of nozzle modules (1400). The nozzle module (1400) comprises a fuel supply pipe (1410) having an internal fuel flow path through which fuel flows from the front side to the rear side, a plurality of manifolds (1430) communicating with the fuel supply pipe (1410) and arranged in a row in a radial direction so that air flow paths are respectively formed at positions therebetween, and a plurality of fuel mixers (1450) disposed along a circumferential direction at the rear side of the manifold (1430) to receive the fuel from the manifold (1430) and inject the fuel. Each of the plurality of fuel mixers (1450) comprises a mixer body (1451) having one end communicating with the manifold (1430), the other end that is opened, and a mixing flow path through which air and the fuel flow, an air inlet port (1470) formed on a lateral side of the mixer body (1451) so that the air is introduced upstream of the mixing flow path, a fuel port (1453) formed inside the mixer body (1451) and discharging the fuel supplied from the manifold to the mixing flow path, and an extension (1460) located at the other end of the mixer body (1451) and whose flow cross-sectional area increases as the extension (1460) extends downstream of the mixing flow path.
