Disclosed herein is a nozzle for a combustor that burns fuel containing hydrogen. The nozzle includes a cylindrical tube through which air and fuel flow, and the cylindrical tube has an inlet formed at a longitudinal end thereof for introduction of a first fluid (e.g., compressed air) into the cylindrical tube. The cylindrical tube has one or more supply ports formed on a circumferential surface of the cylindrical tube for introduction of a second fluid (e.g., fuel such as hydrogen) into the cylindrical tube. The cylindrical tube has at least one fuel/air separator disposed interior of the longitudinal end, the fuel/air separator operative to cause a flow of the second fluid to be sandwiched between two flows of the first fluid before the first and second fluids subsequently mix inside the cylindrical tube. The nozzle may be included in a combustor of a gas turbine engine.

Combustor nozzle, combustor and gas turbine including same

Disclosed herein is a nozzle for a combustor that burns fuel containing hydrogen. The nozzle comprised of a cylindrical tube is configured for introduction of a first fluid (for example, compressed air) and a second fluid (for example, hydrogen or a fuel containing hydrogen). Along an inner surface of the nozzle, one or more fluid vortex generators are disposed. As compressed air flows over the one or more fluid vortex generators, the compressed air swirls inside the nozzle resulting in a turbulent flow of the compressed air. As fuel is then introduced into the nozzle, the fuel encounters the swirling or turbulent flow of compressed air, and the introduced fuel is thoroughly mixed with the compressed air so that the fuel/air mixture will be combusted in a uniform manner. The nozzle may be included in a combustor of a gas turbine engine.

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.

A combustor includes an outer can into which fuel is introduced, an outer head disposed on a front side of the outer can, an inner can disposed inside of the outer can and having a combustion chamber in which a fuel-air mixture is combusted, and an inner head disposed to mix the fuel and the compressed air and supply the mixture into the inner can. The inner head includes a head plate covering a front side of the inner can, and nozzle assemblies disposed to mix the fuel and the compressed air and supply the mixture rearwards. The nozzle assembly includes a nozzle head into which fuel is introduced and nozzles. The nozzles each is coupled between the nozzle head and the head plate to mix the fuel and the compressed air and supply the mixture rearwards. The nozzles each has a shape with a diameter decreasing and increasing toward the rear side thereof.
