Abstract: 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.

Abstract: A method for operating a gas turbine below its rated power, in which CO emissions in the exhaust gas of the gas turbine increase with a reduction of the output gas turbine power, wherein, if a predefined threshold value, which can be selected as desired, for the CO emissions is reached or if a predefined threshold value, specified in relative or absolute terms, for the output gas turbine power is undershot, the combustion temperature in the combustion chamber of the gas turbine is increased. To operate the gas turbine with low emissions, for a constant power output, the exhaust-gas temperature increase generated at the outlet of the gas turbine as a result of the combustion temperature increase is at least partially compensated through the addition of a liquid or vaporous medium.
