A plurality of heat resistant tiles are provided which combine to form an internal liner around the walls of an annular combustor. In a first embodiment a plurality of tiles are arranged in an overlapping relationship to form a fully annular shield around an upstream bulkhead wall. In a second embodiment a plurality of tiles are arranged row by row in an overlapping relationship to form a protective shield around the combustors radially spaced sidewalls. In both embodiments the tiles are attached to the combustor in such a manner that at least one edge of the tiles is clamped against the combustor by an overlapping portion of a neighboring tile. The underside of the tile is exposed to a high pressure flow of cooling air which issues as a film over the exposed surface of the tile. The underside of each tile is sealed by virtue of the clamping effect holding the overlapping edges of adjacent tiles in sealing engagement. The arrangement reduces cooling air leakage on the underside of the tiles, minimizes the number of attachment means required per tile and maximizes the tile surface area available for effusion cooling purposes.
