Abstract (en)
A burner (22) for a gas turbine (1), the burner (22) comprising: - gas flow channel (25) having an axis (24) parallel to the a main gas flow direction (M); - at least a fuel injector (26) comprising at least a streamline body (28) extending straightly across the gas flow channel (25) along a first transverse direction (29) of a plane orthogonal to the gas flow direction (M); wherein the streamline body (28) comprises a lobed shaped trailing edge (31) having turning points (34) and lobes pointing alternatively in opposite direction along a second transverse direction (33) orthogonal to first transverse direction (29) in the plane orthogonal to the gas flow direction (M). wherein the lobed shaped trailing edge (31) has an apex portion (35) substantial parallel to the first transverse direction (29) and two side portions (36) connecting the turning points (34) to the apex portion (35).
