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.

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.
