Definitions
- FIG. 6 shows a gas turbine
- FIG. 7 a combustion chamber
- FIG. 3 shows a component 1 with a corrosion product 10 after the corrosion product 10 has been damaged by a pretreatment according to the invention.
- FIG. 5 shows further damage in the corrosion product 10 according to the method according to the invention. If, for example, the material of the corrosion product 10 has been melted, the material contracts again when it cools down, so that mechanical stresses occur which may lead to crack formation.
- Each turbine stage 112 is formed from two blade rings. Seen in the flow direction of a working medium 113, a row 125 of guide vanes is followed by a row 125 formed from rotor blades 120 in the hot gas channel 111.
- the combustion chamber 110 is designed for a comparatively high temperature of the working medium M of approximately 1000 ° C. to 1600 ° C.
- the combustion chamber wall 153 is provided on its side facing the working medium M with an inner lining formed from heat shield elements 155.
- Each heat shield element 155 is equipped on the working medium side with a particularly heat-resistant protective layer or is made of high-temperature resistant material. Due to the high temperatures inside the combustion chamber 110, a cooling system is also provided for the heat shield elements 155 or for their holding elements.
- FIG. 9 shows an example of a steam turbine 300, 303 with a turbine shaft 309 extending along an axis of rotation 306.
