ABSTRACT:
A fuel-injection nozzle assembly particularly useful for gas turbines is provided with an additive supply arrangement which avoids mixture of the fuel additive with the fuel in the nozzle until the fuel reaches a swirl chamber within the nozzle. The nozzle includes a nozzle holder, a nozzle plunger extending generally centrally of the holder and fuel inlet passages which are defined between the holder and the plunger. The nozzle exhaust opening is located centrally of the plunger and the swirl chamber is defined to extend between the end of the nozzle plunger and the nozzle exhaust opening. The additive supply arrangement directs the additive through the nozzle to a discharge point within or adjacent the swirl chamber. The additive supply arrangement of the invention may consist of a supply conduit extending centrally of the nozzle plunger, supply conduits extending directly through the fuel inlet passages or supply conduits extending either externally of the nozzle walls or internally through the walls themselves.
