Proposed are a jet nozzle, and a combustor and a gas turbine including the jet nozzle. The jet nozzle is formed on an inner surface of a combustor to supply fluid into an interior of a liner of the combustor in a direction intersecting with a progress direction of combustion gases primarily combusted in a combustion chamber in the interior of the liner. The jet nozzle includes a body section provided with a fluid inlet on a first end, through which fluid is introduced, and a fluid outlet on a second end, through which the fluid introduced through the fluid inlet is discharged while generating a vortex, and a baffle section formed on an inner peripheral surface of the second end of the body section and configured to enhance the generation of a counter-rotary shear layer vortex in the fluid discharged out of the fluid outlet through the body section.

Jet nozzle, combustor, and gas turbine including same

Disclosed are a jet nozzle, and a combustor and a gas turbine including the jet nozzle. The jet nozzle is formed on an inner surface of a combustor to supply fluid into an interior of a liner of the combustor in a direction intersecting with a progress direction of combustion gases primarily combusted in a combustion chamber in the interior of the liner. The jet nozzle includes a body section provided with a fluid inlet on one end, through which fluid is introduced, and a fluid outlet on the other end, through which the fluid introduced through the fluid inlet is discharged, and a swirler section provided inside the body section to allow a portion of the fluid introduced into one side of the body section to rotate in a clockwise direction and to allow the rest of the fluid introduced into the other side of the body section to rotate in a counterclockwise direction.

Disclosed herein is a nozzle for a combustor that burns fuel containing hydrogen, which includes a plurality of mixing tubes through which air and fuel flow, and a multi-tube configured to insert the mixing tubes thereinto and support the same, wherein each of the mixing tubes has an inlet formed at a longitudinal end thereof for introduction of a first fluid, and a plurality of supply ports formed on a circumferential surface thereof for introduction of a second fluid, the mixing tube has a plurality of first supply ports formed on a first surface thereof, and a plurality of second supply ports formed on a second surface facing the first surface, and the first supply ports are staggered with the second supply ports.

Combustor nozzle, combustor, and gas turbine including the same

A hollow nozzle including a tubular nozzle casing and a plurality of rotary vanes arranged radially along an inner surface of an inlet of the nozzle casing, through which compressed air is introduced, forming a hollow center at the center of the nozzle casing through which the compressed air flows, each of the rotary vanes including a first fuel injection hole through which a first type of fuel having a predetermined flame propagation speed is injected toward the hollow center, and a second fuel injection hole through which a second type of fuel having a higher flame propagation speed than the first type of fuel is injected, a combustor including the hollow nozzle, and a gas turbine including the combustor.

Hollow nozzle, combustor including hollow nozzle, and gas turbine including combustor

Proposed are a jet nozzle, and a combustor and a gas turbine including the jet nozzle. The jet nozzle is formed on an inner surface of a combustor to supply fluid into an interior of a liner of the combustor in a direction intersecting with a progress direction of combustion gases primarily combusted in a combustion chamber in the interior of the liner. The jet nozzle includes a fluid inlet, through which fluid is externally introduced, and a fluid outlet including a first fluid outlet member, through which a portion of the fluid introduced through the fluid inlet is discharged so as to be rotated in one direction, and a second fluid outlet member, through which the rest of the fluid is discharged so as to be rotated in a direction different from the rotation direction of the fluid discharged from the first fluid outlet member.

Disclosed is a hybrid power generation facility. The hybrid power generation facility includes a gas turbine including a compressor configured to compress air introduced from an outside, a combustor configured to mix the compressed air with fuel and to combust the air and fuel mixture, and a turbine configured to produce power with first combustion gas discharged from the combustor, a boiler including a combustion chamber and a burner installed in the combustion chamber and into which the first combustion gas discharged from the turbine of the gas turbine is introduced, a steam turbine through which steam generated in the combustion chamber passes, a first GT (gas turbine) pipeline connected between the turbine of the gas turbine and the burner, a first air pipeline connected to the first GT pipeline to supply oxygen to the burner, a first oxygen sensor installed at an inlet of the burner to measure an oxygen concentration of a fluid flowing into the burner, and a first GT damper installed in the first GT pipeline to control a flow rate of the fluid flowing through the first GT pipeline according to the oxygen concentration measured by the first oxygen sensor.

Hybrid power generation equipment and control method thereof

Disclosed are an air supply device and an air supply method for a hybrid power generation facility in which a gas turbine compresses air introduced from an outside, mixes the compressed air with fuel, and burns a mixture of the compressed air and the fuel to produce combustion gas.
