Condensing steam turbine
Martynek, Filip ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Content of this thesis is design of one-housing condensing steam turbine with two uncontrolled extractions. First part is describing design of balance scheme. Including cycle joints calculation, design of equipment for whole steam and condense cycle. Thesis continues with preliminary and detail design of regulativ stage. Main goal of this part is thermodynamic calculation of flow channel. Second part is describing lubricating oil and cooling system. Contains process description of lubricating oil scheme including calculation, specification of components and pipe branches design. Diploma thesis is finished with detail lubricating oil scheme.

Turbine efficiency as a function of speed
Woffová, Helena ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The subject of the thesis is condensing steam turbine with the required power of 50MWe and set input and output parameters. The turbine is designed as a two-body turbine. There is also designed balance scheme with reheating, regeneration and air condenser. Subsequently, the thermodynamic calculation for three variations of high pressure part with different speeds is demonstrated. The result is evaluated in terms of calculated efficiency and also in an economic point of view. The output is a selection of the variation with the best parameters. Then the basic dimensioning calculations, the design of the leveling piston and the sealing system follows for this variation. A simplified section of this part is drawn. Finally, the balance scheme is adjusted based on the data and calculated for limited performance as well.

Steam Turbine for the Waste to Energy
Szelecky, Zsolt ; Fichtl, Richard (referee) ; Kracík, Petr (advisor)
The content of this thesis is the design of a condensing steam turbine with an output of 80 MWe to a waste incinerator with impulse blading. In this work are elaborated proposals and calculations of balancing schemes, which are used in the next part of the work as a foundation for calculation of the blades part of the turbine. The blades part is designed for two operations - for full condensing operation and for full demand operation. The turbine should contain one process offtake and three unregulated offtakes. Besides that, the thesis solves basic strength control. The thesis is finished with a technical drawing of the longitudinal cut of the turbine.
