Abstract
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).
