progressive trends in energy exploitation of fossile fuels
Horák, Pavel ; Přibil, Rudolf (advisor) ; Matějíček, Luboš (referee)
This paper, as literature retrieval, evaluates progressive trends in development of technologies for energetic use of fossil fuels. The introduction is focused on reasons for increase of energetic efficiency of combustion processes, especially reasons for using of fossil fuels and their consumption over the world and in Czech Republic. Next chapter focuses on mainly used fossil fuels, which means coal, crude oil and its derivatives and natural gas. Those are evaluated in term of quality and historical progress, too. Fundamental chapter analyses particular improvements but also complex technologies used in energetic, for example using of gas turbines, assets of Kalina cycle, complex technology of Integrated Gasification Combined Cycle (IGCC), combined heat and power production (CHP), combined cycle gas turbine (CCGT) or pressurised fluid bed combustion (PFBC).

Contactless level measurement
Pribula, Wojciech ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
The~thesis begins with an~analysis of~methods of~water level measurement in~high-pressure system. This~systems are placed in~heating plants and power plants and they work with the water whose temperature exceeds 300\,°C and whose pressure is above 10\,MPa. Thesis present method of~differential pressure with the~derivation of~the~correction element and also is~described capacitive method, especially Hydrastep system. This~work prepares theoretical foundation under creating algorithm for level detection using image recognition. Also it considers suitable hardware as~camera and light for illuminating and highlighting the~level. It~includes outline of~captured image editing and detection algorithm. The next part of thesis is dedicated algorithm itself. There are described classes and methods that are used for level detection or for debugging. Also, there are specified necessary modifications of watermark and requirements for watermarks surroundings thats are necessary for proper functioning of the algorithm.

Cogeneration influence on power industry and power market in Czech Republic
Dudáš, Michal ; Cerman, Marek (referee) ; Macháček, Jan (advisor)
The main goal of this master’s thesis is to find out the impact of future development in combined heat and power technologies, especially the impact on power market in Czech Republic regarding to historical development of photovoltaics and subsidy policy. There are three scenarios of installed power growth designed including calculations of renewable energy source financial fee as well as overall evaluation. The paper also deals with current status of combined heat and power technologies in Czech Republic, European Union and USA as well as legislature framework of CHP in Czech Republic and EU. There are also kinds of state grants described. In economical part of the paper there are NPV’s of particular cogeneration units calculated. The calculations were made both with current investment costs and reduced investment costs.

Up-to-date technology for energy utilisation of biomass and waste
Krňávek, Martin ; Frýba, Lukáš (referee) ; Kropáč, Jiří (advisor)
The bachelor‘s thesis deals with technologies for energy utilisation of biomass and waste. The introductory part is dedicated to biomass, its division and sources of biomass suitable for thermal treatment. The main part describes and compares technological units for energy utilisation of biomass, which is important for the Czech market. Furthermore there is described selected technologies for flue gas cleaning suitable especially for thermal treatment of waste. A basic design calculation of technological unit fired with wood chips for combined heat and power production is included here.

Dietární opatření při chronické pankreatitidě
Pavková, Lucie
Chronic pancreatitis (CHP), along with the acute form of the inflammatory diseases of the pancreas. While acute pancreatitis (AP) is really a matter with which one can meet only once in your life, mortality is still 25-30 %. Unlike acute pancreatitis, a chronic disease of this type is defined as a condition in which there is a permanent loss of external secretory function of the pancreas replacing the function of the pancreatic parenchyma tissue. I have chosen the CHP directly to pointed out the seriousness of this disease that affects more and more people and attention to external and internal factors that this disease can both positively and negatively influenced. There is diet as an important factor. That includes strict dietary measures which are necessary for patients with this disease. I explore the possibilities of diet and construct a suitable diet for each stage of the disease with the help of nutritional therapist.

Possibilities of Application of Producer Gas from the Gasification of Biomass
Pohořelý, Michael ; Jeremiáš, Michal ; Kameníková, Petra ; Svoboda, Karel ; Skoblia, S. ; Tošnarová, Markéta ; Šyc, Michal ; Punčochář, Miroslav
In the paper, physico-chemical principles of gasification of biomass are explained and illustrated and the possibilities of producer gas cleaning for different potential applications are mentioned. In the second part, the possibilities of transformation of energetic gas to electric energy or to alternative or current transport fuels are described.
