The use of flue gas for the biomass gasification
Švácha, Filip ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
The aim of this thesis is to describe the process of biomass gasification using gas simulating the composition of flue gas – a mixture of oxygen, carbon dioxide and water vapor. In the research part of the thesis the issue of gasification with the focus on fluidized bed gasification and the effect of the gasification medium used on the gasification process is discussed. In the practical part the thesis deals with the design, realization and evaluation of the experiment on a real device. The aim of the experiment is to determine the effect of the exact composition of the mixture of these three media on the gasification process and on the quality of the gas generated. The aim is to find the optimum composition for obtaining gas with the highest possible lower heating value, which contains as little tar as possible. At the end of the work, the results from the experiment are presented and described.
Storage systems for renewable energy
Švácha, Filip ; Kracík, Petr (referee) ; Poláčik, Ján (advisor)
The aim of the thesis is to describe the current possibilities of storing electricity from renewable sources focusing on hydrogen technologies. In the first three parts, the question of energy sto-rage from renewable sources, the current energy storage options and the actual energy storage in hydrogen are discussed in the form of research. The last part is practical and its aim is to compare the current possibilities in designing a system that stores energy in hydrogen. Subsequently, the most favorable option is chosen and compared to other energy storage methods.
