Seal for use between injector and combustion chamber in gas turbine

摘要

A seal assembly for use between an injector and a combustion chamber in a gas turbine. A liner at least partially defines the combustion chamber, and the liner has at least one tubular liner collar, through which an injector is inserted. In one embodiment, the liner collar has a partially convex outer diameter and a floating collar is positioned at least partially around the liner collar. The floating collar has a retention member having a first end fixed to the floating collar and a second end configured to abut the convex outer diameter of liner collar, wherein the retention member maintains the floating collar at a radial distance from the injector less than a radial distance between the liner collar and the injector.
