Abstract: A combustion chamber with a jacket arranged around a principal axis of the combustion chamber, a ceramic tube that is arranged inside the jacket, wherein an intermediate layer is arranged between the jacket and the ceramic tube. The jacket is at least partially conical. The ceramic tube is under axial stress in the jacket along the principal axis. The ceramic tube is an assembly of multiple heat shield segments. The heat shield segments each have a hot side that is designed to come into contact with a hot medium, a cold side that is opposite the hot side and is oriented toward the jacket, and a circumferential rim between the hot side and the cold side. In the cold state, individual heat shield segments of a segment row have, on the rim, bearing surfaces that the adjoin the cold side and gaps that open toward the hot gas side.
