description: The theme of the final qualification work: âStrength assessment of the structural elements of the stator part of the high-pressure cylinder and the medium-pressure cylinder of a condensing steam turbine with a capacity of 320 MWâ. The first section of this work presents the design of a typical steam turbine plant. High and medium pressure cylinder bodies, nozzles, impeller, bearings are considered separately. The second section of this paper presents the theory of creep. The definitions of creep curves, creep limit is considered, and the main creep hypotheses are also identified.In the third section, together with aerodynamic strength calculations, the nozzle chest of the high-pressure cylinder, the nozzle vane of the first stage of the high-pressure cylinder, and the nozzle vane of the second stage of the medium-pressure cylinder are performed. Stresses in these details, their deflections are determined. Creep deformation calculations were also performed for these parts with a service life of 20 years. The prototype of this turbomachine is K-300-240-5.
