High-speed Steam Turbine
Albrecht, Jan ; Škorpík, Jiří (referee) ; Fiedler, Jan (advisor)
Main aim of presented master thesis is focused on construction of high speed steam turbine. Steam turbine is designed based on parameters of waste incineration plant in Brno. First chapters shortly summarized historical development, transformation process and work principal of steam turbine. Consequently on first captures is in depth described impulse and reaction blading including expansion in i-s diagram and basic equations for efficiency calculations. In major part of master thesis is firstly discussed conceptual possibilities of turbine application for given parameters. Based on chosen concept is compiled algorithm for thermodynamic calculation for each turbine module. Simplify calculation of gearbox is included as well. Based on calculations are compiled construction drawings of all parts of steam turbine.

Technology for liquefaction gases and its use and distributing
Štěpánek, Jindřich ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This thesis deals with technologies for gas liquefaction and storage. The first section summarizes the development of liquefaction technology using expanders and throttling valves, followed by current technology. This is especially a rotary expanders. The storage technology is the above-ground storage of cryogenic tanks. The thesis includes proposals turbine wheels for liquefaction lines and included two proposals liquefaction cycles.

Surface Condenser for Steam Turbine
Szöcs, Ladislav ; Komorous, Daniel (referee) ; Fiedler, Jan (advisor)
The aim of this thesis is to design a surface condenser with lateral exhaust. A research in the field of surface condensers with lateral exhaust takes place before the design. Core of the thesis is a thermodynamic design of the heat exchanger, calculation of pressure losses on the side of coolant water, check of the tube bundles from standpoint of oscillation and a design of air removal pipeline. Finally a design of the condenser is supported with a drawing attached in the supplement.

Low-temperature biogas purification
Hřebíček, Martin ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The aim of this thesis is the issue of low-temperature cleaning of biogas. He briefly acquaint the reader with the technology of production of biogas and its possible use. Provide requirements for low-temperature treatment and purification of biogas to the needs of downstream equipment. Provide an overview of the possibilities of suitable production systems applicable cold. Develop your own design facilities for low-temperature treatment of biogas

Wet surfaces drying using air streams
Gusnarová, Hana ; Hejčík, Jiří (referee) ; Hejčík, Jiří (referee) ; Jaroš, Michal (advisor)
Diploma thesis submit processing and evaluation of experiment which was made at University of Hertfordshire. Aim of this experiment was practically confirm and compare efficiency of drying bottles with blower and compressor. The next purpose was to suggest solution against recondensation on dry surface of bottles. Diploma thesis involves also economy calculation. In the diploma thesis was described issues of drying and condensation, realized analysis of drying equipment and methods of air conditioning. As the most suitable and the most cost effective way of drying was at the base on experiment and energy and economy calculation chosen tested turbo blower 587. As the solution, against recondenzation was created anticondensation tunnel. As the most suitable way for condition the dew point inside the tunnel for require value was chosen desiccant rotor Munters.

Evaluation of methods for determining an air humidity in building constructions
Nogová, Tereza ; Šuhajda, Karel (referee) ; Žák, Antonín (advisor)
This thesis compares the methods for the determination of air and moisture condensation in the construction. There are descriptions of the various methods and formulas for measuring humidity and methods for the calculation of condensation in building structures. The practical part describes the development of a method for verifying the condensation of moisture in construction. Parts of this work are the materials and methods for the development of the humidity sensor. There were used two methods – capacitive and resistive for measuring moisture condensation. In the conclusion is the evaluation of the humidity sensor and compares the results of individual measurements.
