High-speed Condesing Steam Turbine
Klíma, Petr ; Trojan, Aleš (referee) ; Fiedler, Jan (advisor)
ith one controlled extraction and one uncontrolled extraction, calculation of the flow channel at all stage, design and calculation of the regulation valve and create connection diagram of steam turbine and air cooled condenser. At the beginning of this work is an overview of manufacturers of steam turbines and their unified products. Master thesis was developer with G-Team, a.s. as using calculations and the instructions given in the recommended literature with supporting CFD simulations to determine the loss coefficients and FEA simulations to determine the eigenfrequencies blades.

Project of optimalization and cooperation of power units
Hübková, Ivana ; Mastný, Petr (referee) ; Radil, Lukáš (advisor)
This bachelor´s thesis deals with heat circulation in condensing thermal power plants and the possibilities of increasing their effectiveness. Specifically it addresses several topics, namely: "increasing of inlet steam parameters, improving of vacuum in the condenser, regenerative heating, reheating of steam and, last but not least, the supercritical steam parameters." Furthermore, it also deals with losses in heat circulation, power balance and specific consumption. Another part of this thesis deals with optimization of operations and cooperation of two power plant units. A case study shows the optimal power division at load. The cost and consumption characteristics of these blocks are plotted. An insight into the future of Czech energetics is made, theorizing about the advantages of dividing electrical energy distribution, from the point of view of economy, environment, and primarily, technology.

Steam Turbine for Compressor Drive
Beran, Petr ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The goal of this diploma thesis is design of steam turbine for driving a compressor with mechanical power of 25 MW, while using a standard API 612. In the first chapter of this work there is calculation of the steam mass flow about value of 23.17 kg/s, the next chapter deals with the design of control stage with the diameter of 0.715 m, inner power of 1673.6 kW and thermodynamic efficiency of 68 %. The following chapter includes thermodynamic calculation of stage part about power of 26.37 MW at designed rotation speed 5722.5 rpm which corresponds to 105 % of rated speed and thermodynamic efficiency 84 %. For control stage and stage part there is a strength calculation control. The thesis also includes basic design of gland sealing system, the design of balance piston with diameter of 0.543 m and the choosing of axial and radial bearings due to acting forces. The conclusion chapter deals with operating characteristic of designed steam turbine. The thesis includes mechanical drawing of turbine.

Condensing Steam Turbine
Kracík, Petr ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
Diploma thesis named Condensing steam turbine deals with heat scheme balancing computation of condensing steam turbine K55 and her design. This turbine with 5 unregulated take-offs and overpressure blading type, is computed with (c_a/u) method in the middle of blading diameter. Regulation degree is chosen with impulse blading and feet cross section is checked on durability. At the end of the thesis turbine consumption characteristic is derived from the zero output up to the nominal output. Integrated part of this thesis is conceptional design of longitudal turbine section.
