    • A novel combined pressure atomizing nozzle for gas-turbine burners is provided, with which an improved adaptation of the atomizing quality of liquids to the respective load conditions, i.e. good premixing over the entire load range, can be realized. To this end, the pressure atomizing nozzle comprises a nozzle body (1) having at least two separate feed passages (7, 12) for at least one liquid (14, 29, 31) to be atomized. The first feed passage (7) is at least partly enclosed by the second feed passage (12) and is connected downstream to an outer space (5) via a discharge orifice (11). The second feed passage (12) is likewise connected to the outer space (5), in which case the second feed passage (12) has at least two discharge orifices (13) to the outer space (5).
    • 提供了一种用于燃气轮机燃烧器的新型组合压力雾化喷嘴,可以实现液体的雾化质量与各种负载条件的改进适应,即在整个负载范围内的良好预混合。为此,压力 雾化喷嘴包括喷嘴主体(1),其具有用于待雾化的至少一种液体(14,29,31)的至少两个分离的进料通道(7,12)。 第一进料通道(7)至少部分地被第二进料通道(12)包围,并通过排出孔(11)连接到外部空间(5)的下游。 第二进料通道(12)同样连接到外部空间(5),在这种情况下,第二进料通道(12)具有至少两个到外部空间(5)的排出孔(13)。
