| 摘要 |
The invention relates to a burner (1) of a gas turbine having a flame holder (30; 30') axially adjoining a combustion chamber (20) for stabilizing a flame. In order to achieve an increased service life of the burner, the flame holder (30; 30') has at least one elongated depression (30a; 30a') in or adjacent to a flame attachment region (31; 31') subjected to the flame, which depression provides a thermal expansion space for material of the flame holder (30; 30') that is located in the flame attachment region, so that material stresses are reduced. |
