Abstract: A tubular combustion chamber system for a gas turbine unit includes a plurality of annularly arranged transition lines, which are designed to be connected at the upstream ends thereof to respective burners and to conduct hot gas produced by the burners to a turbine. The tubular combustion chamber system has a hot gas distributor, which is designed to be connected to the turbine and defines a ring channel, which is open to the turbine and into which the downstream ends of the transition lines lead. A gas turbine unit includes a plurality of annularly arranged burners, a turbine and a tubular combustion chamber system which connects the burners to the turbine.

Abstract: A combustion chamber, in particular for a gas turbine, includes a support structure, a plurality of retaining elements fastened to the support structure, and a plurality of heat shield elements which jointly form a heat shield and which each have a hot gas side, a cold gas side and end faces which interconnect the hot gas side and the cold gas side, the retaining elements interlockingly engaging in recesses in the heat shield elements. The retaining elements each have at least two engagement portions for interlockingly engaging in the recesses in a heat shield element, which engagement portions are interconnected in a tensionally rigid manner and are tensionally rigid themselves. Spring elements extend between the support structure and the heat shield elements, which spring elements are designed in particular as leaf springs and effect a frictional connection between the engagement portions of the retaining elements and the heat shield elements.

Abstract: A seal for sealing a gap in a combustion arrangement of a gas turbine. The seal is formed by a L-shaped angle profile and a clamping profile. Both profiles have on the opposite side an engagement flank for fastening in a sealing groove and a sealing flank bearing against one another. The clamping profile further includes a holding portion, which is located opposite the associated sealing flank and also bears against the sealing flank of the angle profile, and a clamping portion connecting the sealing flank to the holding portion.

Abstract: A combustion chamber of a gas turbine having a peripheral support structure and a heat shield arranged therein. The support structure has a reduced cross-section on the downstream side and a stop element on the upstream side. There is a gap between the heat shield and the stop element to compensate for different strains and tolerances. For reduction of the cooling air consumption, a peripheral sealing groove which is open towards the heat shield and has a sealing element arranged therein is provided in the stop element, which sealing element rests against the heat shield and covers the gap.

Abstract: A ceramic resonator for combustion chamber systems and combustion chamber system, wherein the resonator is annular when seen in the axial throughflow direction and has cavities in the interior, the cavities having at least one resonator neck per cavity as a connection to the inner surface of the ceramic resonator. By using a ceramic resonator, the amount of cooling air required is significantly reduced.

Abstract: A resonator formed as a ring for a gas turbine combustion chamber, includes an outer shell and an inner shell, wherein one part of a hot gas channel of the gas turbine combustion chamber is delimited by the inner shell, wherein at least one Helmholtz resonator is arranged between the outer shell and the inner shell.

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.
