The present invention relates to a burner for a combustion chamber of a gas turbine plant, with an injection device for introducing gaseous fuel into the burner. The injection device has a body which is arranged in the burner and which has at least one nozzle for introducing gaseous fuel into the burner. The body is configured as a streamlined body which has a streamlined cross-sectional profile and which extends with a longitudinal direction transversely with respect to a main flow direction prevailing in the burner. The at least one nozzle has its outlet orifice at an trailing edge of the streamlined body.

1. A burner for a second combustion chamber of a gas turbine plant with sequential combustion having a first and a second combustion chamber, the burner comprising: a mixing space which is delimited by a burner wall and adjoins an outlet side of the burner; through which a gas flow can emerge from the mixing space into a combustion space of the second combustion chamber;an injection device for the introduction of at least one gaseous fuel into the burner, the injection device comprising: at least one body arranged in the burner; andat least one nozzle for introducing the at least one gaseous fuel into the burner, the at least one nozzle comprising an outlet orifice at or in a trailing edge of a streamlined body; and,wherein the at least one body is configured as the streamlined body having an uninterrupted streamlined cross-sectional profile extending in a longitudinal direction perpendicularly or at an inclination to a main flow direction prevailing in the burner;wherein the streamlined body extends through the burner wall, continuously spans across the entire extent of a flow cross section of the burner from one portion of the burner outer wall and terminates at an opposite wall portion. 2. The burner of claim 1, wherein the streamlined body is arranged centrally in the burner with respect to a width of a flow cross section. 3. The burner of claim 1, wherein the streamlined body is arranged in the burner such that a straight line connecting the trailing edge to a leading edge extends parallel to the main flow direction of the burner. 4. The burner of claim 1, wherein a plurality of separate outlet orifices of a plurality of nozzles arranged next to one another are arranged at the trailing edge. 5. The burner of claim 1, wherein at least one slit-shaped outlet orifice, is arranged at the trailing edge. 6. The burner of claim 1, wherein a main injection direction of each nozzle is oriented parallel to the main flow direction of the burner. 7. The burner of claim 1, further comprising an introduction device for introducing a carrier gas arranged in the streamlined body. 8. The burner of claim 7, wherein at least one outlet orifice for the introduction of carrier air is provided at the trailing edge of the streamlined body. 9. The burner of claim 1, wherein the streamlined body has a symmetrical cross-sectional profile. 10. The burner of claim 1, wherein the burner has a cylindrical shape, the profile of the streamlined body is symmetric and parallel to the main flow direction at a longitudinal midpoint, and the profile of the streamlined body is rotated or twisted in opposing directions relative to the longitudinal axis on both sides of the longitudinal midpoint, in order to impose a mild swirl on the main flow. 11. A burner for a second combustion chamber of a gas turbine plant with sequential combustion having a first and a second combustion chamber, the burner comprising: a mixing space which is delimited by a burner wall, and which adjoins an outlet side of the burner; through which a gas flow can emerge from the mixing space into a combustion space of the second combustion chamber;an introduction device for introducing a carrier gas; andan injection device for the introduction of at least one gaseous fuel into the burner, the injection device comprising: at least one body arranged in the burner; andat least one nozzle for introducing the at least one gaseous fuel into the burner, the at least one nozzle comprising an outlet orifice at or in a trailing edge of a streamlined body; and,wherein the at least one body is configured as the streamlined body extending through the burner wall and having an uninterrupted streamlined cross-sectional profile continuously extending in a longitudinal direction perpendicularly or at an inclination to a main flow direction prevailing in the burner from one portion of the burner outer wall and terminates at an opposite wall portion,and wherein the introduction device for introducing carrier gas is arranged in the streamlined body. 12. The burner of claim 11, wherein the streamlined body is arranged centrally in the burner with respect to a width of a flow cross section. 13. The burner of claim 11, wherein the streamlined body is arranged in the burner such that a straight line connecting the trailing edge to a leading edge extends parallel to the main flow direction of the burner. 14. The burner of claim 11, wherein a plurality of separate outlet orifices of a plurality of nozzles arranged next to one another are arranged at the trailing edge. 15. The burner of claim 11, wherein at least one slit-shaped outlet orifice, is arranged at the trailing edge. 16. The burner of claim 11, wherein a main injection direction of each nozzle is oriented parallel to the main flow direction of the burner. 17. The burner of claim 11, wherein the streamlined body has a symmetrical cross-sectional profile. 18. The burner of claim 11, wherein the burner has a cylindrical shape, the profile of the streamlined body is symmetric and parallel to the main flow direction at a longitudinal midpoint, and the profile of the streamlined body is rotated or twisted in opposing directions relative to the longitudinal axis on both sides of the longitudinal midpoint, in order to impose a mild swirl on the main flow.
