A separator (10) for a two-head combustion chamber which comprises a plurality of segments (11) that are arrayed circumferentially and spaced apart a distance (x) from one another and that are affixed to appropriately shaped sheetmetal (12, 13) of the combustion chamber. Each segment (11) is shaped as an elongated, hollow body with an upper wall (17) and a lower wall (18). The segments are cooled by air from an upstream portion of an end of the combustion chamber entering the segments (11) and exhausting by a plurality of orifices (34) in the segment walls (17, 18). The upper and lower segment walls (17) and (18) are respectively heat-protected by two sets of tiles (40, 41), each of the tiles straddling two adjacent segments, being spaced a distance from the walls (17, 18) to subtend an enclosed space (46, 47) therebetween, and having at least one tile orifice (48, 49, 50) which allows the cooling air from the segments (11) to exhaust into the heads.
