1. A combustor nozzle comprising a plurality of nozzle modules, each nozzle module comprising:
a fuel supply pipe having an internal fuel flow path through which fuel flows from an upstream side to a downstream side based on a flow direction of the fuel in the internal fuel flow path;
a plurality of manifolds communicating with the fuel supply pipe, parallelly extending in a circumferential direction, and arranged in a row in a radial direction, wherein there are at least three manifolds in the plurality of manifolds; and
for each of the plurality of manifolds, a plurality of fuel mixers, disposed along the circumferential direction at the downstream side of a respective manifold, receives the fuel from the respective manifold and injects the fuel,
wherein each of the plurality of fuel mixers comprising:
a mixer body having one end communicating with the respective manifold, wherein a tip is formed at an opposite end of the mixer body;
a shroud disposed to surround an outer circumferential surface of the mixer body to guide an airflow; and
at least one fuel port formed through the mixer body to inject fuel,
wherein each of the plurality of manifolds has a radially inner end surface and a radially outer end surface,
wherein the radially outer end surface of each manifold from among the plurality of manifolds and the radially inner end surface of an adjacent manifold from among the plurality of manifolds, which is radially adjacent to the each manifold, forms a space therebetween, such that each space between radially adjacent manifolds from among the plurality of the manifolds forms an air inlet flow path,
wherein the plurality of nozzle modules is composed of a plurality of outer nozzle modules circumferentially arranged in an annular shape as a whole and a central nozzle module disposed at a center on an inner side of the outer nozzle modules,
wherein each of the plurality of manifolds included in each of the outer nozzle modules has a concentric arc shape, while each of the plurality of manifolds included in the central nozzle module has a concentric annular shape.
