Method and apparatus for cooling gas turbine fuel nozzles |
摘要 |
A method and apparatus for a nozzle of a gas turbine engine is disclosed that facilitates extending a useful life of the nozzle. The method and apparatus include an impingement baffle plate disposed at a back side of a diffusion tip of the nozzle. The method and apparatus includes the impingement baffle plate formed with an array of orifices creating jets for fuel or purge air to impinge on the diffusion tip. In this manner, cooling via convection through diffusion orifices in the diffusion tip is preserved, and cooling is made more robust.
