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.

Ceramic resonator for combustion chamber systems and combustion chamber system

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.

Tubular combustion chamber system and gas turbine unit having a tubular combustion chamber system of this type

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.

Combustion chamber

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.
