| 摘要 |
The present invention relates to a lance (6) for the introduction of gaseous fuel into a burner (1), in particular premix burner, of a combustion chamber of a gas turbine plant, with a base (7) and a shaft (8) projecting from the latter. In a state in which the lance (6) is installed in the burner (1), the base (7) projects into the burner (1) perpendicularly to a main flow direction (10) prevailing in the burner (1), and the shaft (8) runs parallel to the main flow direction (10). The shaft (8) has at least one nozzle (12) for the introduction of gaseous fuel into the burner (1). The shaft (8) has an axial conical portion (11) tapering with an increasing distance from the base (7).
