Abstract: An improved floating collar assembly for gas turbine combustion units consists of a sheet metal collar with a flat flange and an E seal that is pre-compressed within a block of epoxy. The collar fits over a corresponding fuel nozzle burner tube and is retained on a cap assembly by a flat plate. During assembly, the collar is loose so that it floats, which makes cap assembly easy. During operation, the epoxy used to pre-compress the E seal heats up and burns off, whereupon the E seal opens up and produces a seating load between the collar and plate that is high enough to keep the collar from rotating and thereby reduce collar wear.
