Steam turbine for steam-gas block
Kober, Ondřej ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This master’s thesis deals with the design of two variants of a condensing steam turbine for a steam-gas unit. In the first variant, steam bleeding from the turbine for low-pressure regeneration is considered, in the second variant heat regeneration would be provided by a heat recovery steam generator, which is not the subject of the master’s thesis. Three unregulated steam extractions for the deaerator and two low-pressure heaters are considered for the turbine with steam bleeding. Both turbines were designed with an impulse governing stage and a reaction blading. The result of the design of bleeding variant is a turbine with a speed of 7000 min-1 with 7 cones, 33 stages with power output of 13,69 MW and an efficiency of 81,83%. The turbine without bleeding has a speed of 6500 min-1, 7 cones, 38 degrees, power output of 14,13 MW and an efficiency of 81,97%. The consumption characteristics are given for both turbines at the end. For the steam bleeding turbine, a drawing of the turbine section is attached to the thesis.

Steam Turbine design, Optimization steam reheat pressure
Štaffa, Petr ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The Diploma’s thesis deals with calculation of tree heat schemas with condensing steam turbine with uncontrolled steam extractions for regeneration – tree low pressure heaters, two high pressure heaters and a deaerator. Heat schemas are compared to each other according to reheat pressure. The most efficient schema is used to steam turbine thermodynamic design – design of control stage and blade stages. At the end of diploma thesis a stress analysis of the last rotor blade is made.

Comparison of the concept nuclear power plants feedwater heaters
Špaček, Michal ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The topic of this master thesis is comparison of the concept nuclear power plants feedwater heaters. At the beginning, a brief recherche is written in which the types of nuclear reactors and the heat regeneration system are described. In the next part of the thesis, the heat balance diagram of the nuclear power plant is proposed and the parameters found in the design are further used for the thermal calculation of the feedwater heater of low and high pressure regeneration. The thermal calculation is performed for both horizontal and vertical designs. Finally, a basic dimensional design is made for both designs and these designs are compared with each other.
