Steam Turbine to Drive the Crusher in the Sugar Factory
Ruzsík, Erik ; Lokaj, Jakub (referee) ; Kracík, Petr (advisor)
The thesis is focused on designing of backpressure steam turbine to drive the crusher in the sugar factory having the power input of the 2 200 kW. Thermodynamic calculation of two conceptual variations is gradually implemented in the thesis with the aim to determine the steam mass flow through the turbine. In the first version the control stage is selected as an A-wheel and in the second version as a Curtis wheel. The stage part of both versions consists of series action stages. Furthermore, it contains basic design of the gland steam system and the nozzle control system. Both radial and thrust bearings are designed based on the acting forces. The thesis also includes strength calculation of the selected components. The final part deals with comparison and evaluation of the optimal solution. Due to the small difference in rotor weight (m =19,72 kg), and especially for the less steam consumption (M = 4,87 kg/s), the first version can be considered as an optimal solution. This thesis is amended by a mechanical drawing of the turbine cross section on a common frame with a gearbox.

Gland steam system for a steam turbine
Skala, Šimon ; Šrůtek, Petr (referee) ; Fiedler, Jan (advisor)
The diploma thesis deals with preliminary design of condensing steam turbine with three unregulated steam outputs and its gland steam system particularly its description and design. The steam parameters in key outputs were determined in heat balance. The gland steam system parameters were calculated for different operating conditions. It also describes influence of pressure on performance of turbine in gland steam system. Finally, the inquiry sheet for gland steam system device was created based on calculated values.

Condensing steam turbine
Krška, Jan ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
This master’s thesis deals with the design of a condensing steam turbine for certain parameters. In the initial part of the thesis, a research on steam turbines and types of blading is carried out. The computational part of the thesis is divided into several subchapters which have been made into larger chapters. One of the chapters deals with the thermodynamic calculation of the flow section of a steam turbine for a clamp power of 5 MW, a speed of 11,000 min-1 and a pressure of 0,1 bar (a). The calculation has been optimized for several basic operating parameters that the steam boiler is capable of achieving with respect to the highest possible thermodynamic efficiency of the plant. The work includes the evaluation of the results in the form of a graph. After the calculations for all steam parameters have been performed, the point was selected which with it’s values meets the requirements for the highest thermodynamic efficiency. The optimum operating parameters of this turbine are such that the turbine at a nominal temperature of 490 °C and an operating pressure of 65 bar (a) achieves a clamp power of 5190,220 kW. The thermodynamic efficiency of the steam turbine is 85,07 % and the reheat factor is 1,0634. Subsequently, basic dimensioning calculations were performed. The calculations are followed by a chapter entitled discussion where some important steps are evaluated. The master’s thesis also contains an appendix. It is a conceptual longitudinal section of a steam turbine.

Steam Turbine 300 MW
Veleba, Lukáš ; Kubiš, Zdeněk (referee) ; Fiedler, Jan (advisor)
The Diploma thesis named Steam Turbine 300 MW contains the proposal of the Turboset for the steam section of the gas-steam cycle. There is a calculation of the thermal cycle, and a thermodynamic calculation of the combined high pressure - as well as intermediate pressure and low pressure parts. Strength calculation of particular parts and a check of the critical turbine speed follow on from this. This thesis includes a drawing of the cross-section of HP-IP and partial operations. My thesis has been commissioned by Doosan Škoda Power.
