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.

Mechanical analysis of the subsystem of the tower crane
Urbánek, Roman ; Venský, Jiří (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis deals with the solution of a subsystem of a tower crane with a passive effect (NNTP). First part describes tower cranes and their parts. The following part is a description of the theoretical and physical laws of statics and dynamics. In the practical part, various states of motion of a specific modeled subsystem are calculated, which shows a trolley of the tower crane. The aim of the calculation of each configuration is to determine the numerical values of the contact forces in the links, to analyze the dynamic quantities and to evaluate the functionality of the links. Numerical values of unknown parameters were calculated by solving a system of linear equations in the calculation software Matlab.
