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.

Condesing Steam Turbine 25 MW
Mašek, Martin ; Norbert, Weber (referee) ; Norbert, Weber (referee) ; Fiedler, Jan (advisor)
Master’s thesis deals with design and calculation of one body condensing steam turbine of 25 MW with samples for paper-making industry. The thesis is focused on calculation of the turbine’s heat balance with two technological samples and regeneration which consists of two low pressure heaters and a deaerator with a power reservoir. The steam turbine is designed with a water cooling condenser with down output. The flow part is calculated with lengths of blades. There are basic strength and proportion calculations. In the end of the thesis the turbine’s heat balance is recalculated to 80% and 105% scheme according to an assignment. Another part of this thesis is a drawing of a longitudinal cut of the turbine including a connector with a gearbox.

Backpressure Steam Turbine
Kubiš, Zdeněk ; Ondřej, Štěpánek (referee) ; Štěpánek, Ondřej (referee) ; Fiedler, Jan (advisor)
The theme of the master’s thesis is to design a 60 MW single-casing steam turbine for the two-stage district water heating. The turbine is designed for cogeneration cycle, has four uncontrolled extractions and the outlet down to the heater. First, there is the thermodynamic calculation of the turbine operation with 100 % steam mass flow. Further, the detailed design of flow part with the strength calculation of blades and diaphragms is drawn. By the end of the thesis, the required operations are compared and corresponding heat balancing diagrams are listed. The thesis also includes a turbine longitudinal section.

Condensing Steam Turbine
Víšková, Jaroslava ; Ing.Václav Urbánek (referee) ; Fiedler, Jan (advisor)
The theme of this master thesis is one body steam turbine of 150MW with reheat. There is calculated heat balance of the system with three low pressure heaters, deaerator and two high pressure heaters. Next part deals with calculation of blades and its lenght. Next are the attachments of blades into stator and rotor parts of the turbine. By the end of the thesis there is recalculation of heat balance scheme and blading followed by calculation of parameters for operation of turbine in 75% and 50% of the rated power output. The output of the whole thesis is drawing of horizontal cut of the turbine.

High Pressure part Steam Turbine
Martinek, Miroslav ; Ing.Richard Fichtl (referee) ; Fiedler, Jan (advisor)
The target of this work is to created balance comparIsion of versions of high speed and standard speed HP parts of steam turbine and for the more suitable version to make optimization. Optimization consists of flow part, choosen profile blades and construction calculations. Control calculations for rotor and pipeline were made in order to draw longitudinal section of HP part.
