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.

Wood chip belt conveyor
Kamínek, Jan ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The bachelor's thesis in the introduction contains research on the topic of the belt conveyor and an analysis of the anchoring of the conveyor. In the following chapters there is a design and functional calculation of a belt conveyor for transporting wood chips with an assumed specific weight 650 kgm-3. The belt conveyor was designed with a transport distance of 19 m, a height difference of 3 m and a transport performance of 19,000 kg·h-1. A more detailed analysis of the properties of the transported material is also carried out. Finally, the strength of the driven and drive shaft is verified by calculation.

Frame of the elevator cabin
Řehulka, Filip ; Zeizinger, Lukáš (referee) ; Pokorný, Přemysl (advisor)
This bachelor thesis focuses on the design of the elevator frame, its strength calculation and functional calculation of the elevator system with a load capacity of 600 kg. It was necessary to determine the use of the elevator, the number of people carried and the type of drive that use elevator belts instead of ropes. The lift is designed for 6 people and installed in a four-storey residential building with traction drive with a 2:1 roping and a rated speed of 1 m·s-1. The frame structure was modelled in Autodesk Inventor, using C and square sections. Safety calculations were performed according to ČSN EN 81-20 and ČSN EN 81-50.
