Abstract: In a gas turbine dual fuel nozzle including a main nozzle body with a support flange having a liquid fuel and atomizing air nozzle structure centrally extending therethrough with a fuel and atomizing air discharge structure arranged at its free end and a fuel gas supply structure arranged around the free end of the fuel and atomizing air discharge structure wherein the fuel gas supply structure has a front face extending inwardly adjacent the fuel and atomizing air discharge structure and having a central opening permitting the discharge of liquid fuel and atomizing air therethrough, the front face has bores extending therethrough in radial symmetry in a circular array and radial slots formed therein between said bores and the central opening so as to eliminate hoop stresses in the front face around its central opening.
