Disclosed herein is a combustor nozzle that includes at least one cluster composed of a plurality of tubes through which air and fuel flow, wherein the cluster includes a main tube through which air and fuel flow, a sub-tube disposed to surround the main tube, a fuel supply part positioned inside the main tube to supply fuel, and a plurality of wing parts protruding radially from the fuel supply part, each having one end coupled to the fuel supply part and the other end in contact with an inner peripheral surface of the main tube.

Combustor nozzle and gas turbine including the same

A micro-mixer includes a plurality of fuel tubes through which air and fuel flow, a casing accommodating the plurality of fuel tubes therein, an injection part formed as a pyramidal protrusion on one side of the casing and connected to a front end of the fuel tube to inject the air and the fuel, and a fuel supply divided into a plurality of fuel supply parts to supply the fuel to the fuel tubes.

Micro-mixer with multi-stage fuel supply and gas turbine including same

A micro-mixer includes a plurality of fuel tubes through which air and fuel flow, a casing accommodating the plurality of fuel tubes therein, and a plurality of injection parts each formed as a pyramidal protrusion on one side of the casing and connected to a front end of the fuel tube to inject the air and the fuel, wherein each of the plurality of injection parts has an inclined injection hole formed obliquely with respect to an extension direction of the plurality of fuel tubes on at least one side of the pyramidal protrusion.

Micro-mixer and gas turbine including same

A nozzle assembly for injecting fuel and compressed air into a combustion chamber of a gas turbine combustor is provided. The nozzle assembly includes a nozzle body disposed in the combustor and having a coolant outlet on one end of which an inside of the nozzle body communicates with the combustion chamber, a spray nozzle disposed in the nozzle body and including a plurality of first nozzle tubes each having a first flow path formed therein to allow combustion air to flow into the combustion chamber and a fuel hole formed to supply fuel, and a second nozzle tube having through-holes to allow the first nozzle tubes to pass therethrough and a second flow path formed to supply fuel, and a diaphragm disposed inside of the nozzle body and including a plurality of coolant flow holes through which a coolant supplied to the nozzle body is supplied towards one end of the nozzle body and a plurality of tube holes through which the first nozzle tubes pass.
