Liquid fuel cartridge for a fuel nozzle

A liquid fuel cartridge for a gas turbine fuel nozzle in a combustor of a gas turbine, the liquid fuel cartridge comprising:

• a tube having an inlet end and an outlet end with one or more fuel exit orifices, wherein the inlet end is coupled to at least one source of a mixture of liquid fuel and water, and the one or more fuel exit orifices face a combustion chamber of the combustor;
• a homogenizer located within said tube, adjacent and upstream of said outlet end, said homogenizer formed by three adjacent and axially-spaced disks which include:
• a first upstream disk provided with a first center opening;
• a second intermediate disk provided with a second center opening;
• and
• a third downstream disk provided with a third center opening surrounded by a plurality of outer openings.

A fuel nozzle for a combustor of a gas turbine comprising:

• a nozzle body including annular, concentric fuel and air passages about a centrally located liquid fuel cartridge;
• said centrally located liquid fuel cartridge comprising:
• a tube having an inlet end and an outlet end with one or more fuel exit orifices, wherein the inlet end is coupled to at least one source of a mixture of liquid fuel and water, and the outlet end faces a combustion chamber of the combustor;
• and
• a homogenizer located within said tube, adjacent and upstream of said outlet end, said homogenizer formed by a substantially cylindrical body open at opposite ends, and a first row of circumferentially-spaced flanges projecting radially outwardly from said substantially cylindrical body with radially-outer edges of said flanges engaged with an inner surface of said tube and slots between the flanges and extending from the substantially cylindrical body to the inner surface of the tube, wherein a length of the homogenizer is less than a length of the tube.
