Design of Energy Systems Using Hydrogen as Fuel
Slováček, Adam ; Bébar, Ladislav (referee) ; Houdková, Lucie (advisor)
Purpose of this thesis is wisdom accumulation from current area of energetic use of hydrogen and future systems. In overview is presented possible processes where dominate steam methane reforming. In main part of thesis, steam methane reforming will be analyzed and electrolysis also. Actual results will be discussed. Next part is about energetic use of hydrogen based on thermochemical properties and safety. Used of hydrogen will be divided to areas thermal generation as burner‘s section, electric generation as fuel cell‘s section, mechanical energy as combustion engine’s section and finally chemical transportation of energy. At the end will be made a promising energy systems using hydrogen as fuel which can be applied in a large scale.

Higher Heating Value of Sewage Sludge
Mikluš, Michal ; Bělohradský, Petr (referee) ; Houdková, Lucie (advisor)
The thesis is focused on problems of thermal treatment of sludge from wastewater treatment plants. The main objective is to establish a formula for calculating higher heating value (HHV) and lower heating value (LHV) of sludge based on its chemical analysis. The work is divided into two main parts: The theoretical part deals with the characteristics of sludge, thermal treatment of sludge, it isn´t omitted higher heating value and lower heating value. The main topic of a practical part is formulation of eguations for HHV and LHV calculation. Chemical analysis of sludge samples were supplied by TÜV NORD Czech s.r.o., together with the values of HHV and LHV. The calculations were verified by the program MINITAB.

Hydrogen Production from Biomass
Ožana, Ferdinand ; Beňo, Zdeněk (referee) ; Houdková, Lucie (advisor)
First part of this master´s thesis decribes the basic properties of hydrogen, its utilization in industry and economy. Greater attention is focused on the possibilities of hydrogen produciton. Next part describes anaerobic fermentation and optimum conditions for hydrogen production. The main part of the thesis deals with posibility of hydrogen production in an experimental laboratory unit using brewer´s grains as a primary material. The experiment was aimed to find suitable process conditions for hydrogen production. The quantity of produced gas and his quality depending on the amount of brewer´s grains and frequency of the dosage was observed. Based on the experiment, some recommendations are proposed for further research. An automatic feeding system is the most important of them. It will improve the quality of experimental work. A separate chapter is devoted to the automatic feeding system.

Sewage sludge drying - theory and practice
Sirový, Martin ; Elsässer, Thomas (referee) ; Houdková, Lucie (advisor)
The thesis deals with sludge drying coming from biological sewage disposal plants from theoretical and practical points of view. The first chapter deals with the sewage disposal plant functioning and with sludge formation there. Furthermore sorts and properties of water treatment sludge are described here. In the second chapter the thesis points the look to the industry drying theory and then to the theory of sludge drying. The third chapter contains a list of current drying chambers convenient for sludge drying and their principles and description. The fourth chapter points to the present practice of sludge drying in the Czech republic. Prospects of the water treatment sludge drying are evaluated in the concluding part.

Disintegration of sludge thickened by flotation
Veverka, Jakub ; Jecha, David (referee) ; Houdková, Lucie (advisor)
The main topic of this thesis is a research of influence of disintegration of sewage sludge on the production of biogas during the process of anaerobic fermentation. The theoretical part deals with issues and specific methods used during the process of waste water cleaning, furthermore it contains simplified description of waste water treatment plants and particular devices. The number of ways of processing sewage sludge and its potential utilization id also discussed. Following parts of the thesis analyze in detail my own process of anaerobic fermentation including important factors influencing this process. Comparison of aerobic and anaerobic fermentation and ecological perspective on the issue are included in this part. Another important part of the thesis deals with disintegration and description of the disintegration methods and devices. The fundamental part implies the analysis of the executed experiments. Experiments analyze the growth of biogas during anaerobic fermentation depending on the disintegration of sewage sludge. After that the evaluation of the experiments is stated together with economical calculations of the disintegration process executed in laboratory conditions.
