A burner component of a burner. The burner has a flow channel, in which combustion air flows in a flow direction from upstream to downstream. The burner component includes a wall portion, which adjoins the flow channel; a plurality of injection nozzles, which are arranged in the wall portion; and a plurality of vortex generators, which are arranged on the wall portion. The vortex generators have a concavely curved sloped surface rising in the flow direction to improve the distribution of the fuel in the combustion air.

Burner component of a burner, and burner of a gas turbine having a burner component of this type

A burner having a plurality of pre-mixing chambers each having a fuel nozzle for two fuels, the fuel nozzle has a fuel lance extending in a flow direction, in which fuel lance first outlet openings for a first fuel are introduced. The fuel lance is surrounded by an outer pipe having at least one second outlet opening for a second fuel, the first outlet openings oriented radially and the second outlet opening oriented axially, a flow cross-section is formed between the fuel lance and the inside of the pre-mixing chamber and vortex generators are arranged on the fuel lance. At least one vortex generator is arranged upstream of the first outlet openings and downstream of the second outlet opening. The distance of the first outlet openings from an end of the pre-mixing chamber is at least three times as large as a cross-section of the pre-mixing chamber.
