Aerodynamic design of the last stage of a steam turbine
Jeřábek, Lukáš ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Diploma thesis deals with calculations of a steam turbine with two uncontrolled extraction points according to the assignment, aerodynamics of the last two stages and operating range with respect to ventilation, range of performance and straining of the last blading under the large condensation pressure deviations. For the first three stages the calculation of prismatic action blades is executed. The fourth and the fifth stages are designed with inconstant reaction over the blades length and their calculation is executed with constant circulation method. For these stages, aerofoil design with respect to their aerodynamic qualities is carried out using Bézier curves. During the whole time verification process of aerofoils qualities, their energy losses and isoentropic Mach number distribution is executed in MISES program in cooperation with Doosan Škoda Power.

Single-Stage Steam Turbine
Susna, David ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Bachelor thesis deals with design of back-pressure sngle-stage steam turbine. This turbine is designed to process technologic steam in chemical factory. Goal of the thesis is to design turbine which can process as much steam energy as possible with specified parameters. Main part of the thesis is thermodynamics calculation, where consideration of using banding is also included. Part of the thesis is also rust design of the turbine.

Steam turbine for mechanical drives
Zýbal, Jan ; Pospíšil, Lukáš (referee) ; Fiedler, Jan (advisor)
This bachelor’s thesis deals with steam turbines for mechanical drives. The first part de-scribes a production of steam turbines for mechanical drives in Siemens, s.r.o., Industrial Turbomachinery, subsidiary company in Brno, steam turbine’s components and particular products from company’s portfolio. The second part aims to a thermodynamic calculation and design of turbine’s steam path according to given conditions.

Biomass Retrofit 250 MW Steam Turbine
Novák, Martin ; Josef, Švagr (referee) ; Josef, Švagr (referee) ; Fiedler, Jan (advisor)
There is a description of modernisation steam condensing turbine in this Master´s thesis. Electric output is decreased from 250 MW to 160 MW. This thesis is divided into two parts, there is a calculation of heat balance in first part and a calculation of blading in second part. Detail drawing and heat balance are the most important results of this Master´s thesis.

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.
