Black coal position in the Czech energy sector
Kolarčík, Vojtěch ; Škvařil, Jan (referee) ; Pospíšil, Jiří (advisor)
This bachelor‘s thesis describes role of coal (especially the black) on the energy industry of Czech Republic. It attends to present sort of reserves in the Word and by us. Next it evaluates actual sort of energy industry. Closely analyses the power station Dětmarovice. It looks for possibilities enjoyment of coal in the future not only in the energy sector.

Fossil fuels use in Czech Republic
Trávníček, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The aim of the bachelor thesis is to collect facts about fossil fuels and their utilization in the Czech Republic. Firstly, the thesis discusses the fossil fuels and their division in general. The main part of the thesis is focused on mining and utilization of different kinds of fossil fuels in the Czech Republic with the emphasis being put on the brown coal, black coal and the natural gas. The oil and the lignite are briefly dealt with as well. The thesis includes the statistics of the fossil fuels‘ production of the mining companies, the summary of the big energy facilities in the Czech Republic and the mapping of their fuel bases.

Analysis of thermal power plants environmental impacts using radioanalytical methods
Král, Dušan ; Ing. Ondřej Huml, Ph.D., KJR FJFI ČVUT v Praze (referee) ; Katovský, Karel (advisor)
Operation of classical power sources, like coal fueled thermal power plants, causes more or less strong impact on surrounded environment. Beside to the generally discussed CO2 emissions, there are CO, SOx, NOx too; and also fly ash emissions containing various trace elements depending on coal quality. Heavy trace elements carried by fly ash generate locally distributed fallout and contaminate soil in the power plant neighborhood for many years. These elements may be detected in soil samples as well as in biomass. Objectives of this work are to find and quantify trace elements in soil samples near Oslavany hard coal fueled thermal plant, which was in operation from 1913 to 1993. Power plant did not use any advanced fly ash filters. Hard coal was used as a fuel for power plant and it was mined locally in Rosice-Oslavany coal district in very deep mines (up to 1428 m). Coal contained a lot of trace elements. A mine as well as power plant is for more than 20 year closed, but trace elements can be still find in the environment. Main goal is to find these elements using activation analysis and gamma-ray spectrometry methodology. We have assembled thirty six soil samples in square lattice drawn around Oslavany power plant brownfield. On behalf of cooperation with colleagues from the Czech Technical University in Prague and their Open-Access project, we irradiated samples in three vertical channels of VR-1 research nuclear reactor. Irradiated samples were transported to gamma spectroscopy & activation analysis laboratory and measured by HPGe detector. Gamma spectra were analyzed and some trace elements identified. We have determine relative and absolute concentration of found elements. We observe and determine activity and weight of As, U, Ba, La, Eu, Mn, K, V, Mg and Na only. Results show a real suspicion for increase of trace elements in soil samples of hard coal power plant surroundings.

Design of Steam Boiler
Kadlec, Tomáš ; Nechvátal, Ondřej (referee) ; Skála, Zdeněk (advisor)
This thesis is focused on design of black coal combustion boiler of 160t/h output. It consists of several parts. First, stechiometric calculations and enthalpy of air and gas are made, then heat balance of boiler and the boiler losses are calculated, and also thermal efficiency is determined. In next step, the combustion chamber is designed and its thermal calculation is made. Then, each of heating surfaces are designed, and in the last step overall energy balance of the boiler is checked. The scheme of pressure system and design documentation added.

Fosil Fuels in Czech Republic
Ertelt, Tomáš ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
The object of this bachelor thesis is to explore fossil fuels in the Czech Republic their kinds, qualities, occurrence, usage, extraction, import and export. Thesis focuses on black coal, brown coal, anthracite, lignite, peat, oil and natural gas. This thesis analyzes their availability, deposits, processing and usage in the Czech Republic. Production statistics of their extraction by 2011 are addend.

Fosil Fuels in Europe
Zemánek, Josef ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
Aim of this work is to explore facts about fossil fuels – their kinds, qualities, occurrences. It deals with black coal, brown coal, lignite, peat, oil and natural gas and covers their deposits and possible exploitation of fossil fuels in the Czech Republic. Production statistics from the year 2009 are added.

Black Coal Mining in Czech Rep
Vínovský, Jan ; Škorpík, Jiří (referee) ; Lisý, Martin (advisor)
Throughout history, coal mining has dominated the 19th and especially the 20th century. The period of decline in mining began in the 90s. Between 1990 and 2019, there was a decrease of 88.13%, specifically from 30,714 kt to 3,645 kt of mined coal per year. Currently, only four active mines are in operation and the other two are in a conservation state. The forecast for the future of the sector is very unfavorable. In addition to the economic crisis, there are also reserves of extractable coal, which are currently around 25,000 kt. It is currently planned to end mining at the ČSA and Darkov mines at the turn of 2020 and 2021, ČSM Mines should be closed by 2022 at the latest, which will completely end black coal mining in the Moravian-Silesian Region and the entire Czech Republic.
