A burner tube for a gas turbine, comprising a premix fuel nozzle (12, 22) comprising a nozzle tip disposed in said burner tube, said burner tube having an internal wall, an open internal volume having a length extending between an upstream end and a downstream end of the burner tube, a longitudinal axis and a cross-sectional area perpendicular to the longitudinal axis, said nozzle tip comprising: (a) an outer body having an outer body external face facing the downstream end of the burner tube, said outer body external face having a smaller cross-sectional area than the cross-sectional area of the burner tube; and (b) one or more segments radiating radially outwardly toward the internal wall of the burner tube from said outer body, wherein each segment has a proximal end disposed adjacent to the outer body external face and a distal end disposed in a direction toward the burner tube, wherein each segment comprises a segment downstream face angled relative to the longitudinal axis of the burner tube towards the downstream end of the burner tube at an angle of 105 to 165 degrees; whereby, when the gas turbine is in operation, an axial flow field of an air and fuel mixture flows through the burner tube and around the nozzle tip, and two or more recirculation zones of differing radial extent are generated on the nozzle tip by the segments to provide strong flame holding and flame propagation, wherein the outer body surrounds an inner plenum, said inner plenum adapted to receive cooling air, said outer body having an open end and a closed end, said closed end having an internal face adjacent to the inner plenum characterized in that each segment comprises: (a) an internal conduit having an open proximal end and a closed distal end, the open proximal end in fluid communication with the inner plenum, wherein the air is adapted to pass from the inner plenum into the internal conduit; and (b) a plurality of segment bore holes between the internal conduit and the segment downstream face, wherein the bore holes provide fluid communication between the internal conduit and the segment downstream face, to provide for the air to pass from the internal conduit through each segment. (a) an outer body having an outer body external face facing the downstream end of the burner tube, said outer body external face having a smaller cross-sectional area than the cross-sectional area of the burner tube; and (b) one or more segments radiating radially outwardly toward the internal wall of the burner tube from said outer body, wherein each segment has a proximal end disposed adjacent to the outer body external face and a distal end disposed in a direction toward the burner tube, wherein each segment comprises a segment downstream face angled relative to the longitudinal axis of the burner tube towards the downstream end of the burner tube at an angle of 105 to 165 degrees; whereby, when the gas turbine is in operation, an axial flow field of an air and fuel mixture flows through the burner tube and around the nozzle tip, and two or more recirculation zones of differing radial extent are generated on the nozzle tip by the segments to provide strong flame holding and flame propagation, wherein the outer body surrounds an inner plenum, said inner plenum adapted to receive cooling air, said outer body having an open end and a closed end, said closed end having an internal face adjacent to the inner plenum characterized in that each segment comprises: (a) an internal conduit having an open proximal end and a closed distal end, the open proximal end in fluid communication with the inner plenum, wherein the air is adapted to pass from the inner plenum into the internal conduit; and (b) a plurality of segment bore holes between the internal conduit and the segment downstream face, wherein the bore holes provide fluid communication between the internal conduit and the segment downstream face, to provide for the air to pass from the internal conduit through each segment. (a) an internal conduit having an open proximal end and a closed distal end, the open proximal end in fluid communication with the inner plenum, wherein the air is adapted to pass from the inner plenum into the internal conduit; and (b) a plurality of segment bore holes between the internal conduit and the segment downstream face, wherein the bore holes provide fluid communication between the internal conduit and the segment downstream face, to provide for the air to pass from the internal conduit through each segment.
