Steam turbine for municipal waste incinerator
Holík, Michal ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The thesis focuses on the design of a condensing steam turbine for a waste incineration plant. The design includes the supply of heat to the district heating system with a temperature gradient of 55/75 °C and an output of 15 MWt in the summer period, and the supply of heat to the district heating system with a temperature gradient of 65/120 °C and an output of 45 MWt in the winter period. The first stage of the turbine is a controlled stage with impulse blading. This is followed by the stepped section, which consists of 7 cones with a total of 40 stages. These stages were subsequently strength-verified. A balancing piston, gland steam system, and bearings were designed. Finally, the operational characteristic of the turbine was constructed.

Steam turbine for biomass power plant
Urbánek, Roman ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The master's thesis deals with the design of a condensing steam turbine for a biomass power plant with off-takes for heating heaters with a temperature drop of 60/80 °C in summer and 70/125 °C in winter, and off-takes for low-pressure regeneration. The nominal thermal output of the heat exchangers is 0-10 MWt in summer and 0-50 MWt in winter. The thesis includes a detailed design of the flow parts of the steam turbine, from the design of the control stage, the staged part of the turbine, and the strength verification of individual stages to the design of the balancing piston, sealing system, and bearing design. In conclusion, the operational characteristics of the proposed steam turbine are depicted.

Steam turbine for biomass heating plant
Cmajdálka, Ondřej ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This master thesis deals with the design of a condensing steam turbine for a biomass block burning wood chips with one regulated take for a hot water heat exchanger. The temperature gradient for the hot water is 90/110 ° C. The thesis guides through the designing proces of a steam turbine from the thermal scheme proposed according to the specified parameters, through the design of the regulatory stage and the stage part of the turbine, including strength calculation, to the design of the compensating piston, seals system and bearings. Finally, the operating characteristic of the turbine is constructed.

Condensing steam turbine
Prinz, František ; Škorpík, Jiří (referee) ; Kracík, Petr (advisor)
The main topic of this master thesis is the design of condensing steam turbine. In the beginning the heat scheme with low pressure regeneration is calculated. There are chosen 2 low pressure heat exchangers and 3 steam outlets from the turbine. In the main part the thermodynamic proposal with reaction blades is designed, which consists of the regulating stage and the stage part of turbine. The survivability of the turbine is checked by the calculation of mechanical strength. In the end the turbine is checked at reduced mass flow and the turbine characteristic is plotted. The designed steam turbined has a regulating stage and 34 stages in the stage part, has a power of 45873 kW with thermodynamic efficiency of 83.6%. The reheat factor is 1.052.
