A burner component of a burner. The burner has a flow channel, in which combustion air flows in a flow direction from upstream to downstream. The burner component includes a wall portion, which adjoins the flow channel; a plurality of injection nozzles, which are arranged in the wall portion; and a plurality of vortex generators, which are arranged on the wall portion. The vortex generators have a concavely curved sloped surface rising in the flow direction to improve the distribution of the fuel in the combustion air.

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 retaining element () for retaining a heat shield tile on a supporting structure: A fastening section () fastened to the supporting structure. A retaining section () having a retaining head (), which engages an engagement device on the heat shield tile. The fastening section () top side () faces the cold side of the heat shield tile when the retaining section engages the heat shield tile. Scaling of the supporting structure due to the entry of hot gas can be avoided particularly effectively by means of the retaining element. At least one cooling-air passage () arranged in the fastening section () has an inlet opening () and at least one outlet opening () which is arranged in a lateral surface () and/or on the top side () of the fastening section. Cooling air, which enters the inlet opening () and exits from the at least one outlet opening, can be conducted in a respective outflow direction () by the cooling-air passage, which outflow is parallel to the cold side and avoids impingement cooling of the heat shield tile. The fastening section is arranged on the supporting structure such that the cooling-air passage () corresponds to at least one cooling-air channel () in the supporting structure.

A burner incorporating a pilot cone and a mounting insert is provided. The pilot cone is constructed as a pilot cone assembly which is decoupled from the mounting insert. Further, an operating method for increasing the service life of a burner which incorporates a pilot cone assembly and a mounting insert is provided. The pilot cone assembly has a cone side and incorporates at least one further side where the further side is arranged to be essentially parallel to one of the sides of the mounting insert and spaced apart from it, so that between the further side and the side of the mounting insert there is a defined gap. In an operation of the burner, the gap is significantly reduced by the thermal expansion in at least at one point of contact between the further side and the side of the mounting insert. Finally, an assembly method is provided.

Burner, operating method and assembly method

A burner assembly having a fuel distribution ring, number of fuel nozzles which are mounted on the fuel distribution ring in the direction of low is provided. The fuel distribution ring has a ring-shaped surface in the direction of flow and wherein the fuel distribution ring center and an opposite outer outer side and wherein there is at least one slot on the surface between the fuel nozzles and the at least one slot extends on the surface from the outside to the inside. There is at least one recess arranged on the surface and the at least one recess also partially includes the outside of the fuel distributor.
