Testování zbytkové produkce bioplynu z fermentačních zbytků
Havelka, Kamil
This diploma thesis is focused on testing residual biogas production from fermentation residues. This thesis is divided into two parts - theoretical and practical. Theoretical part is divided into few chapters. At first I will explain basic consepts such as principle of the generation of biogas, the formation of biogas fermentation residue by dividing the output of biogas plants, waste fermination residue etc. The practical part is based on theoretical knowledge. Practical part contains actual testing of residual biogas production from fermentation residues and results of this testing.

Design and Implementation of Modular Bioreactor with Use of Wasted Heat
Peterka, Michal ; Bajko, Jaroslav (referee) ; Baxant, Petr (advisor)
The aim of the thesis is to extend the existing project of further use of waste heat from biodegradation processes and to improve bioreactor design. The first part summarizes the theoretical knowledge of the use of biomass and waste resources. The practical part is initially focused on the development of the bioreactor structure, the following part deals with the use of heat pipes for heat dissipation and the last chapter is about heating the fermenter and collecting the generated gas. Designed construction of the new bioreactor proved to have more advantages than the previous type. Heat pipes have a great potential for heat dissipation from the bioreactor, next steps should lead to a system of interconnected heatpipes and controlled heat dissipation. Biogas consumption initially seemed like a good idea, but the processes within the fermenter are more complex than expected. After a short time, the processes inside the fermenter have stopped, therefore this path of research will require further exploration.

Utilization of biomass energy
Horváth, Martin ; Bok, Jaromír (referee) ; Procházka, Zdeněk (advisor)
Restoring sources of a energy and their development brings questions how these can be these sources the best utilized. The main aim of my bachelor`s thesis is an acquainted with methods of biomass conversion to energetic potential and his advantage. Than is mentioned proper project of the biogas plant and calculation of produced electric energy quantity in select cogeneration unit base on data on specific excrements production bred pigs and biogas production from slurry. The result is a variant evaluation of economy of the biogas plant operation for agricultural enterprise according to number of bred pigs and possibility of electric energy utilization.

Biogas plants
Hudečková, Eva ; Moskalík, Jiří (referee) ; Fortelný, Zdeněk (advisor)
This thesis deals with biogas plants. In thesis are described suitable inlet feedstock for anaerobic fermentation, described proces of fermentation and there are mentioned basic elements of biogas plant. In next part of thesis was described concrete biogas plant and there were worked out energy and economic balance. In simplicity there were calculated return of investment and economic benefits for farm.

Biogas technologies
Martanová, Iveta ; Jecha, David (referee) ; Beňo, Zdeněk (advisor)
This bachelor's work deals with technology of conception and production of biogas from biodegradable waste. In the introductory part there is elaboration of biogas facts, the principle of biogas origin and the usage of biogas in practice. The main part is dedicated to individual technology of the biogas production. There are descriptions of technological equipment for gas producing and descriptions of individual methods of waste processing indicating their advantages and disadvantages.

Hodnocení tepelně-technických vlastností stavebních konstrukcí vybraného objektu odpadového hospodářství
Štěrbová, Hana
The aim of this work is to detect the thermal defects of the walls on the solid-state biogas plant of Šumperk city, situated in Horní Temenice. In the first part, I give the survey of literature dealing with biogas and the conditions for its formation, storage and use. Next part is focused on basic information concerning building construction and also primarily aspects of thermal processes. The second part of this work provides description of the biogas plant analyzed. The particular accent is placed on its weaknesses in the design for the conservation of thermal energy. On the basis of IR thermography, I finally evaluate detected thermal defects of the walls.
