Retrofit HP Section Steam Turbine 300MW
Vaľočík, Jan ; Buršík, Michal (referee) ; Buršík, Michal (referee) ; Fiedler, Jan (advisor)
The aim of this master‘s thesis is retrofit of a 300 MW tandem compound steam turbinetype K300 - 170 with three casings and reheat of steam. In the first part a heat balance of the cycle is calculated for given nominal parameters. Further the thesis is focused only on the high pressure section of the turbine, for which the flow section is designed based on thermodynamic calculations and appropriate blade profiles are selected. Then the stress control of the blading is done. The thesis is concluded with estimation of power loss due to shaft seals and real power output of the turbine is calculated. This thesis also includes a drawing of axial section of the high pressure section of the turbine.

Steam turbine
Sedlák, Pavel ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The diploma thesis concentrates on a project of condensing steam turbine with uncontrolled extraction. These topics are analyzed in more detail: design of thermal diagram, thermodynamic calculation and turbine design concepts. First two topics are solved in the calculation section of the thesis. In the construction part are processed a third topic.

Last stage steam turbine
Šabacký, Filip ; Brettschneider, Bohuslav (referee) ; Fiedler, Jan (advisor)
This Master’s thesis deals with a pre-calculation of a steam condensation turbine on a blading mid diameter. The governing stage is solved as a A-turbine wheel, impulse blading. Multistage blading is solved as a reacion stage by ca/u method. Further, detailed calculation of last stage with a twisted blade is made. Thesis contains comparision of obtained results with a results provided by contracting company. Final part of thesis deals with a design of sectional shape of a turbine blade.

Optimizing injections from the condensate pump
Kordiovský, Jan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with the topic of the optimization calculation of the mass flow of injection from the condensing pumps of the second degree to the condensate of heating steam, flowing from the system of separation and reheating, with the main goal to achieve the maximum power of the block of the power plant. There is calculation of the secondary circuit of the nuclear power plant in Dukovany before and after the optimization. In the next part, there is calculated growth of electric power of the block, results are drawn in diagrams and technical solution is designed.

Steam turbine
Skoupý, Pavel ; Ing.Duda (referee) ; Fiedler, Jan (advisor)
The master´s thesis concentrates on a project of steam turbine with controlled extraction points destined for a communal waste incineration plant. First, there the history of devices using steam as a moving medium is introduced and than follows the description of computing program, where the calculation was running. The master´s thesis subject consists in the thermodynamic project of turbine vaning, in basic project of gearbox including the check calculations and in technical economic comparison of single shaft and twin shaft constructional design. The design documentation is worked up according to the calculated outcomes and contains longitudinal section of turbine and dispositional turbine and gearbox settlement.

Retrofit IP-LP Section Steam Turbine 300MW
Pavlik, Richard ; Fichtl, Richard (referee) ; Fichtl, Richard (referee) ; Fiedler, Jan (advisor)
The aim of this master’s thesis is a retrofit of condensing three case steam turbine K300-170 with reheating. In the first part, the heat balance of the system is calculated for given parameters. The design of the flow section is focused on the combined intermediate pressure and low pressure turbine section and it consists of defining rotor and blading characteristics. In the stress control, the stress of the designed blading is checked and for the conclusion the shaft seal losses and their effect on the overall output power of the turbine are estimated. The drawing of axial section of combined intermediate pressure and low pressure turbine section is also included in the thesis.

Steam Turbine 300 MW
Veleba, Lukáš ; Kubiš, Zdeněk (referee) ; Fiedler, Jan (advisor)
The Diploma thesis named Steam Turbine 300 MW contains the proposal of the Turboset for the steam section of the gas-steam cycle. There is a calculation of the thermal cycle, and a thermodynamic calculation of the combined high pressure - as well as intermediate pressure and low pressure parts. Strength calculation of particular parts and a check of the critical turbine speed follow on from this. This thesis includes a drawing of the cross-section of HP-IP and partial operations. My thesis has been commissioned by Doosan Škoda Power.
