| 摘要 |
The present invention relates to a premix burner (10) of a multi-cone type for a gas turbine, comprising a plurality of shells (16a-16d), which are arranged around a central burner axis (11) and are parts of a virtual and axially extending common cone, which opens in a downstream direction, whereby said parts are displaced perpendicular to said burner axis (11) such that a tangential slot (17) is defined between each pair of adjacent shells (16a-16d). The flame front of such the burner (10) is stabilized by providing a virtual common cone with a cone angle, which varies in axial direction. |
