Abstract (en)
An engine (10) can utilize a combustor (14) to combust fuel to drive the engine (10). A fuel nozzle assembly (130) can supply fuel to the combustor (14) for combustion or ignition of the fuel. The fuel nozzle assembly (130) can include a swirler (134) and a fuel nozzle (132) to supply a mixture of fuel and air for combustion. Increasing efficiency and emission needs require the use of alternative fuels, which combust at higher temperatures and faster burn speeds than traditional fuels, requiring improved fuel introduction without the occurrence of flame holding or flashback.
