Abstract
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.
