FUEL INJECTOR DEVICE

Japanese Patent JP2016191546

A

PROBLEM TO BE SOLVED: To provide a fuel injector device of a gas turbine combustor.SOLUTION: A body of a fuel injector device 1 includes a leading edge 11 and a trailing edge 12 and defines a streamwise direction 3 from the leading edge to the trailing edge. The body further has a first surface 101 and a second surface 102 opposite the first surface, each of the surfaces extends between the leading edge 11 and the trailing edge 12, and the surfaces are connected to each other at the leading edge and the trailing edge. The trailing edge 12, when observed in the streamwise direction, has the waveform along a trailing edge intermediate line 13 and, along its extent, deviates in opposite directions from the intermediate line and further includes at least one inflection point 14 along its extent. The fuel injector device further includes first internal fuel supply means and first fuel discharge duct fluid-connecting the first internal supply means with first fuel discharge means 15 opening out to the external of the injector device. The furst fuel discharge duct terminates at the first fuel discharge means arranged at the trailing edge. The first fuel discharge means 15 is arranged at the trailing edge 12 between two trailing edge inflection points 14.SELECTED DRAWING: Figure 1
