Abstract:
A separator ring (10) for an annular combustion chamber comprising two mutually radially offset concentric heads, which are partitioned in an end (2) of the combustion chamber, and appropriately shaped sheetmetal (12, 13), the separator ring (10) comprising:a plurality of segments 11) arrayed circumferentially and spaced apart a given distance (x) from each other, each of the segments (11) being affixed on the appropriately shaped sheetmetal (12, 13) of the combustion chamber,each of the segments (11) being shaped as an elongated, hollow body with an upper wall (17) and a lower wall (18), the upper and lower walls (17, 18) having a plurality of wall orifices (34) formed therein to exhaust cooling air entering the segments (11) from an upstream side of the combustion chamber end (2);a first set of tiles (40) covering the upper walls (17) of the segments (11); anda second set of tiles (41) covering the lower walls (18) of the segments (11);wherein each of the tiles (40, 41) straddles adjacent segments (11), is spaced a distance from the respective wall (17, 18) to subtend an enclosed space (46, 47) therebetween, and has at least one tile orifice (48, 49, 50) which allows the cooling air from the segments (11) to exhaust into the heads.
