A heat shield assembly of a combustion chamber has a supporting structure and heat shield elements arranged on the supporting structure. For fastening, the supporting structure has spring devices fastened therein, into each of which a fastening bolt can be screwed. In order to realize the pre-installation and the later removal of the spring elements contained in the spring device, at a holding sleeve, a contact plate is removably fastened in the holding sleeve on the side facing the heat shield element and a stationary securing plate is arranged on the opposite side.

A heat shield with support structure and a number of heat shield blocks secured thereto, having a cold side facing the support structure and a hot side opposite the cold side. At least one recess is arranged in at least one heat shield block circumferential face, connecting the cold to hot side. An opening connecting the recess to the cold side runs in the circumferential face perpendicularly to the cold side. A securing bolt inserted into the opening secures the heat shield block to the support structure. A bolt head protrudes at least partly into the recess. The securing bolt passes through an angled plate having first limb extending substantially parallel to the circumferential face and second limb extending into the recess. The angled plate has a reinforcing device extending beyond the pure angular shape to increase a resistance of the angled plate against bending due to the securing bolt.

Securing a heat shield block to a support structure, and heat shield

A device () for cooling a supporting structure of a heat shield () to avoid scaling of the supporting structure due to the intake of hot gas. The device has a longitudinal axis () and a cooling air duct (). The device is on the supporting structure with the longitudinal axis () intersecting the surface () of the supporting structure (). In this position, the cooling air duct () extends from a device end () pointing towards the supporting structure. The device has at least one outlet duct downstream in the cooling air duct. The duct emerges out of the device () laterally with respect to the longitudinal axis (). The cooling air duct () corresponds to at least one cooling air passage () in the supporting structure ().

A burner insert for a gas turbine combustion chamber is provided. The burner insert includes a burner insert wall including a cold side and a hot side, an edge delimiting the burner insert wall. The edge includes an edge bar extending at least partially circumferentially and projecting beyond the cold side. A burner opening for inserting a burner is formed in the burner insert wall.

A heat shield element arrangement including a heat shield element for a heat shield arranged on a supporting structure is provided. On each of the two opposing sides running parallel to the installation grooves the heat shield element includes a continuous screw head opening which penetrates the cold side and the hot side of the heat shield element substantially vertically and through which the screw head of the respective screw is arranged to be accessible to the supporting structure, and a spring element may be arranged under the respective screw, which spring element may be extended along the hot side of the heat shield element and the parallel installation groove of the supporting structure. An outer end of the spring element is embodied as a clamping retaining hook which is provided for the purpose of engaging in the laterally recessed retaining groove of the heat shield element.

A mobile cleaning device for cleaning parts of a burner is provided. The mobile cleaning device includes a closable pressure vessel, wherein a nozzle end of the burner is located inside the pressure vessel. An end of the burner, which is used for supplying fuel and is arranged opposite from the nozzle end, is located outside the pressure vessel. Further, a method for cleaning parts of the burner is provided.

Mobile cleaning device and method

A burner having two ignition electrodes and a bracket is provided. The bracket is arranged on the outer surface of the burner and the ignition electrodes are held, at in each case three points of their periphery, in a fixed position using the bracket. A gas turbine with the burner is also provided.
