摘要： Provided is a gas-liquid mixing nozzle (10) including an internal air discharge path (A), an external air discharge path (D), at least one liquid introduction path (B, C) which is disposed between the internal air discharge path (A) and the external air discharge path (D) and introduces a liquid having water and/or fuel as a main component into a nozzle discharge opening (18), and an impact member (22) with which a mixture of the air and the liquid mixed with each other in the outlets of the internal air discharge path (A) and the liquid introduction path (B, C) collides, the outlet of the internal air discharge path (A) and the outlet of the liquid introduction path (B, C) being disposed on the inside of a nozzle in relation to the nozzle discharge opening (18), and the impact member (22) being disposed between the outlets of the internal air discharge path (A) and the liquid introduction path (B, C) and the nozzle discharge opening (18). With the above-described configuration, the gas and the liquid may be highly efficiently mixed with each other, and the generation of water droplets of a liquid may be suppressed, thereby producing finer particles.

摘要： Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zum Betrieb eines Vormischbrenners zu schaffen, welche die Brennstoffzufuhr bei bestimmten Betriebsarten verbessern.
Erfindungsgemäss wird dies dadurch erreicht, dass der Flüssigbrennstoff (2) und das Wasser (27) separat zur Flüssigbrennstoffdüse (17) transportiert, erst dort eine Flüssigbrennstoff-Wasser-Mischung (28) erzeugt und diese anschliessend in einem Vollstrahl (29), mit einem Einspritzwinkel α von kleiner als 10°, in den Innenraum (9) des Vormischbrenners (4) eingedüst wird. Dazu ist die zentral in den Innenraum (9) mündende Flüssigbrennstoffdüse (17) mit einer einfachen Einspritzöffnung (19) ausgebildet. Stromauf der Einspritzöffnung (19) ist eine Mischzone (22) angeordnet, in welche eine Flüssigbrennstoffleitung (20) und eine Wasserzuleitung (21) münden.

摘要： The invention relates to an injector (4) for liquid fuels (6a) and a premix burner, especially for combustion chambers of gas turbines, comprising such an injector (4). The injector (4) comprises a swirl nozzle (14), surrounded by a shielding air channel (11) and having an enlarged cross-section of flow in the area of a nozzle-internal swirl generator (12) for the liquid fuel (6a), which decreases towards an outlet opening of the swirl nozzle (14). The inventive injector allows operation of a premix burner at reduced admission pressure and excellent quality of atomization.
