A fuel nozzle body having a rearward end and a front end with an outer tube which extends from the rearward end to the front end and has radial openings for a first fuel in the region of the front end, and an inner tube which is arranged concentrically to the outer tube and which opens in the region of the front end into a nozzle head, which has additional openings for a second fuel, wherein, in the region of the front end, the inner tube is guided in the outer tube by two fits which are arranged axially between the radial openings and the additional openings, and wherein the first fit closest to the radial openings is configured as a circumferential web around the inner tube, and wherein the second fit is configured with at least one interruption on the perimeter.

Fuel nozzle body

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.
