Design of heat exchanger
Kopřivová, Anna ; Kudela, Libor (referee) ; Milčák, Pavel (advisor)
This bachelor thesis discusses a design of the water-steam type heat exchanger. The nature of heat exchangers is based on increasing the efficiency of thermal circuits. At the beginning of the thesis, a principle of these thermal cycles, namely Carnot’s and Rankine-Clausius’s cycles are described. Furthermore, in this thesis, I deal with heat exchangers alone together with their basic distinction and more detailed description with a closer look at specific sorting of the heat exchangers regarding their construction, which means recuperative, regenerative and direct contact exchangers. Special attention is paid to tubular exchangers, which create the core of thermal computation. Closing part involves a design of a low-pressure tubular heater by means of assigned parameters of work substances at the input and the output.
Energy Mix in the Czech Republic
Fojtl, Martin ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor’s thesis addresses the mixture of energy mix in Czechia. The first part is focused on the evolution of energy mixture up to present days. In the next part, the expected development of the mixture is described from the state energy policy and ecological points of view. Lastly, in the final section, there is a comparison of compositions of electric energy source between Czechia and other countries of a European Union.
Design of a gas turbine for heating plant
Lang, Filip ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
This bachelor thesis deals about design combustion turbine for heating plant. It include deciding of type combustion turbine and its calculation. The thesis consists of four main parts. The first part focuses on the analysis of gas turbine and principle of operation. The second part focuses on the requirements of a particular heating plant. The third part focuses on the selection of a suitable turbine from Siemens and last part contains the thermodynamic calculations of selected gas turbine.
Circuits of nuclear power plants
Pavlíček, Martin ; Kudela, Libor (referee) ; Milčák, Pavel (advisor)
This bachelor's thesis deals with the history and beginnings of nuclear energy, an explanation of the basic knowledge of nuclear energy and an introduction to the issue. Then, the division of nuclear reactors according to various criteria is described. Furthermore, the solution of individual circuits in a nuclear power plant is described according to the type of reactor used. The individual circuits are described at the Temelin nuclear power plant. The last part deals with nuclear safety and various safety systems, without which a nuclear power plant could not be started.
Small Modular Reactors
Tichý, Marek ; Chýlek, Radomír (referee) ; Milčák, Pavel (advisor)
This bachelors thesis is focused on nuclear energy. It describes the generations of nuclear reactors and their representatives. The main goal of this work are small modular reactors which are discussed in more detail. This thesis describes types of reactors, their descriptions and also their use cases.
Cryogenic Technique
Zrůst, Michael ; Milčák, Pavel (referee) ; Kracík, Petr (advisor)
Bachelor thesis deals with technology of cryogenic temperatures, liquefying gases in this temperature interval, effects of these temperatures on materials and insulations. In the introduction, brief history of development of this field. Next part is about gases which get liquefied in cryogenic temperatures and their applications. The largest chapter is chapter about liquefying in which principle of coolers, heat exchangers and liquefiers is described. Next, means of cooling by expansion, cooling cycles used to reach desired temperatures and ways of separating gas mixtures, are specified. In the last chapter insulation used to maintain cryogenic temperatures inside space is discussed.
Biomass gasification with carbon dioxide
Klíma, David ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
This master’s thesis deals with the process of biomass gasification using mixture of CO and O2 as gasification agent. First part describes the gasification process itself, used devices, gasification medium and its influence on the generated gas. Following section covers the experimental part of the work, which is focused on change properties of the generated gas using different ratios of CO2, O2, H2O and air in the gasification mixture. This part also includes processing and evaluation of the results.
Aerodynamic calculation of flue gas part of steam boiler
Faltýnek, Michal ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
The aim of this thesis is to introduce the reader into theory, which is needed to make an aerodynamic calculation of flue gas part of steam boiler. On the back of the knowledge, project documentation and other entry parameters calculate sectional losses for each component and design a ventilator, that is suitable for our requirements.
Accumulation of electricity using liquefied air
Laca, Theodore Nicolas ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
In the research part is a basic overview of vapor thermodynamics is processed. It deals with the historical development of gas liquefaction systems, divided according to the authors of the proposals. It includes basic knowledge of thermodynamics of gas liquefaction. In the field of liquefied gas storage, it contains a brief overview of the division of storage vessels and insulation materials. It also deals with the extract of energy from liquid air. It contains an adiabatic design of electrical energy storage using air liquefaction (LAES). The conclusion describes the proposed design, economic analysis and perspectives of using LAES.
