Abstract

A nozzle assembly (140), a combustor (100), and a gas turbine (10) including the same are provided. The nozzle assembly (140) may include a plurality of nozzle modules (1000) arranged in a circumferentially spaced relationship and configured to discharge fuel and compressed air into a combustion chamber (121), wherein each nozzle module (1000) includes a fuel supply tube (1100), a fuel manifold (1200) coupled to the fuel supply tube (1100), a plurality of fuel injectors (1300) disposed at a rear end of the fuel manifold (1200) in a radially spaced configuration, each fuel injector (1300) being in fluid communication with the fuel manifold (1200) and configured to mix fuel with air to discharge a fuel-air mixture, and a pilot injector (1400) disposed at a central portion of the fuel injectors (1300) and in fluid communication with the fuel manifold (1200), wherein each fuel injector (1300) includes an injector body (1310) defining a mixing passage (1311), an air inflow port (1320) defined through a side surface of the injector body (1310), and a fuel port (1330) defined in the injector body (1310) and configured to discharge fuel from the fuel manifold (1200) into the mixing passage (1311).
