    摘要: The invention relates to a premix burner (10) of the multi-cone type for a gas turbine, comprising a plurality of shells (12a-d), which are arranged around a central burner axis (11) and are parts of a virtual, 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 (14) is defined between each pair of adjacent shells (12a-d).
    A disadvantageous transition piece between the shells and a downstream mixing tube is avoided by bordering the downstream ends of the shells (12a-d) by intersecting planes (17), which are defined by intersecting said shells (12a-d) with a virtual coaxial cylinder of a predetermined radius (R).

    摘要: The combustion chamber (10) of a gas turbine comprises first and second premixed fuel supply devices (11, 12) connected to a combustion device (13) having first zones (14) connected to the first premixed fuel supply devices (11) and second zones (15) connected to the second premixed fuel supply devices (12). The second fuel supply devices (12) are shifted along a combustion device longitudinal axis (16) with respect to the first fuel supply devices (11). The first zones (14) are axially upstream of the second premixed fuel supply devices (12).
