Energy mix development in the Czech Republic
Špaček, Michal ; Sitek, Tomáš (referee) ; Elbl, Patrik (advisor)
The topic of this bachelor thesis is the development of the energy mix of the Czech Republic. The first part is focused on concepts energy mix, energy security and the goals and priorities of state energy policy. Next part describes the development of the Czech energy mix up to present and in this part, the possible future development of the energy mix of the Czech Republic is described as well. In the last part, the energy mix of the Czech Republic is compared to the energy mixes of Slovakia, Poland, Germany and Denmark and the future development of these energy mixes is predicted as well.

Solid fuels boilers
Sitek, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor thesis is focused on solid fuel heating of a detached house. The first section describes most common solid fuels, their composition, characteristics and combustion principle. Following section is about solid fuels boilers with their operation description and most common designs and types. In the end economic and user aspects of four selected boilers are described, such as acquisition and operation costs, operation comfort etc. The resulting graph of total costs over fifteen years can be used for general comparison of selected boilers.

Negative impacts of renewable resources on environment
Kopeček, Marek ; Chýlek, Radomír (referee) ; Sitek, Tomáš (advisor)
Current society understands the need to protect the environment. Renewable energy resources are one of the major topics of environmental protection. Their benefits are reducing greenhouse gas emissions and reducing dependence on fossil fuels. The production process, operation, recycling, and possible accidents of renewable energy resources are investigated in each chapter. Attention was paid mainly to the most used renewable sources. Finally, the negative impacts are evaluated, and it is defined which renewable energy resources could be classified as ecological.

Negative impact of renewable energy sources
Kleinová, Martina ; Lachman, Jakub (referee) ; Sitek, Tomáš (advisor)
The main focus of this work was to delve deeper into the issue of renewable energy. Firstly, we have looked at the different types in general and their characteristics, but in particular we have focused on the negative impacts they bring. Since renewable energy sources are our future, it is necessary to become familiar with their potential, possible shortcomings, the degree of severity of these problems and possible solutions. In the last part of the thesis, we looked at the use of renewables in the Czech Republic and evaluated the current policy and energy market.

Particle concentration measurement by various methods
Kuruc, Jan ; Kalivodová, Markéta (referee) ; Sitek, Tomáš (advisor)
In addition to the gaseous components, the Earth's atmosphere contains solid and liquid particles from various sources. These particles are monitored and examined mainly due to their environmental and health impacts and many methods are used for their monitoring and measurement. The aim of the research part of this thesis is to bring the topic of aerosol particles, namely their division, the methods of formation closer, to indicate the impact of these particles on the environment and human health, and to further describe the measuring instruments used to measure the concentration of fine particles. The practical part of this work is the measurement of particle concentration using the impactor, the monitoring of particle concentrations and other data measured by the Brno-Arboretum measuring station, as well as the subsequent evaluation of the measured and monitored data. The primary output from the almost 18-day impactor measurement is considered to be the total concentration of all captured particles of 11.56 g/Nm. The size distribution of the captured particles is plotted in the graph, as well as the quantities monitored from the station. The data obtained is compared at the end and the links linking these data are given.

Heat recovery from waste water
Paulíková, Kateřina ; Sitek, Tomáš (referee) ; Toman, Filip (advisor)
The aim of the Bachelor’s Thesis is to discuss the view of wastewater as a source of thermal energy. The thesis is divided into three main chapters. The first chapter aims to acquaint with the issue of wastewater. The analysis of systems for heat recovery from wastewater is summarized in the following chapter. Also there is a focus on systems installed directly at the generation of wastewater, inserted into the sewerage pipes and finally the creation of thermal energy in wastewater treatment plants. All mentioned systems are built to be economical and ecological efficient as possible. Finally, the last chapter includes an overall evaluation of the systems.

Ultrafine combustion particles
Sitek, Tomáš ; Skála, Zdeněk (referee) ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with issues of fine and ultrafine particles formation during thermal decomposition and combustion of biomass. An introduction is devoted to a utilization of biomass as fuel. A following part describes the gas products emerging generally during combustion process. A current emission and air pollution situation in the Czech Republic as well as the health impacts of solid pollutants on human are also mentioned. Within an experimental measurement three basic factors that have impact on fine particles formation during combustion of beech wood (i. e. oxygen content in combustion atmosphere, type of the sample and size of the sample) were thoroughly analyzed. Attention was paid to a progress of thermal decomposition and combustion of sample with respect to the particles formation. Finally, a measurement of fine particles amount was accomplished in a real boiler successively with four different biomass pellet types.

Thermonuclear fusion for power generation
Osolsobě, Jiří ; Elbl, Patrik (referee) ; Sitek, Tomáš (advisor)
Controlled thermonuclear fusion opens up the possibility of using similar principles that take place in stars to produce energy on planet Earth. A fusion power plant would represent a stable, safe, emission-free and, for the foreseeable future, inexhaustible source of energy. Currently, the most researched fusion device is a tokamak using magnetic confinement of plasma, which is likely to become the reactor of the first fusion power plant. The international ITER tokamak will be a breakthrough project for the further development of controlled thermonuclear fusion, with the main objective of testing a number of key technologies and the suitability of the tokamak as a fusion power plant reactor. According to the European Union's plans, construction of the first EU-DEMO fusion power plant should start around 2040. This bachelor thesis provides a comprehensive overview of the origins, current status and future prospects of thermonuclear fusion and its energy applications.
