Fuel nozzle attachment in gas turbine combustors

摘要

In a gas turbine, a linear stem extends through a diffuser and a combustor cowl into a sleeve that is attached to the swirler in such a way that the sleeve can move relative to the swirler but is supported on the swirler. The stem slides into the sleeve and contains a fuel nozzle that supplies fuel through a sleeve outlet to a swirler inlet.
