Vortex generating arrangement and gas turbine with such vortex generating arrangement

The invention relates to a vortex generating arrangement and a gas turbine with such a vortex generating arrangement, and more specifically provides a vortex generating arrangement (23), especially for a premixing burner of a gas turbine, comprising an air conducting channel (26) of predetermined height (h) extending between two essentially parallel channel walls (34, 35) and having a predetermined direction of air flow, and further comprising a plurality of vortex generators (27) arranged in said channel (26). An improved mixing is achieved by said vortex generators (27) each having the shape of a triangular plate, which is arranged essentially perpendicular to said channel walls (34, 35) and oriented relative to said direction of air flow with a predetermined off-axis angle 0 degree, and a first side (27b) of said triangular plate being oriented perpendicular to said channel walls (34, 35). 本发明涉及涡流发生布置结构以及带有这种布置结构的燃气轮机，更具体地提出种涡流发生布置结构（23），其尤其用于燃气轮机的预混合式燃烧器，所述布置结构包括预定高度（h）的空气传导通道（26），其在两个基本平行的通道壁（34，35）之间延伸并
