A method for optimizing energy conversion installation service measures, wherein the energy conversion installation has at least the following machines: at least one gas turbine; at least one generator; and optionally at least one steam turbine; wherein repairs are carried out on the at least one machine, in particular a defective component or defective components of the at least one machine either is/are or will be replaced by a new, identical component or new, identical components and/or repaired; and wherein, while carrying out these repairs, further measures for extending the service life of machines or the components thereof and/or further measures for optimizing machines or the components thereof are carried out.

The use of different ceramic layers allows different configurations of gas turbines to be produced each of which is optimized for a respective use of base load operation or peak load operation.

Method for treating a gas turbine blade and gas turbine having said blade

Through the use of different ceramic heat insulation coatings () on turbine blades, it is possible to produce or restore different configurations of gas turbines, which are then optimized for a respective baseload operation application or peak load operation application. Differences in the sprayed-on heat insulation coatings () can be generated by means of a different material composition of the powder, for example zirconium oxide, by means of a different number of layers (), by means of different coating thicknesses and/or by means of different porosities.

A method for testing an overspeed protection apparatus of a single-shaft system that includes: a) operating the system at nominal speed and under electrical load, wherein the load is selected to be low enough that, after dropping the load, the speed of the system rises such that the speed remains below steam turbine threshold speed lower than gas turbine threshold speed, such that first overspeed protection is triggered when the speed of the steam turbine reaches the steam turbine threshold speed, and second overspeed protection is triggered when the speed of the gas turbine reaches the gas turbine threshold speed; b) dropping the load; c) increasing the mass flow of the steam introduced into the steam turbine and/or of the fuel introduced into the gas turbine such that the speed of the steam turbine reaches the steam turbine threshold speed; d) testing whether the first overspeed protection is triggered.

An optical waveguide with a tubular or hose-like housing is provided, which is used in a high-temperature environment, such as, for example, in a burner. The housing has an input opening, an output opening and a center line extending from the input opening to the output opening. In the interior of the housing, transparent spheres are lined up along with center line. The light is guided on account of the refraction of a light beam upon entering and exiting from the transparent spheres.
