Improvement of the Thermal Circuit of the Bioreactor and Its Verification
Lapčík, David ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The main idea of this bachelor thesis is a research of existing bioreactor solutions related to their practical implementation with different design, biomass composition, aeration modifications and heat exchange to recover heat from the process of aerobic composting. The conclusion of this work will be evaluation of the results of temperature measurements on functional prototypes depending on their properties and calculations of theoretical heat balance including their comparison.

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.

Bioreactor monitoring and control for optimal heat gain
Hujňák, Jan ; Bajko, Jaroslav (referee) ; Baxant, Petr (advisor)
This bachelor thesis deals with thermal energy generation in biodegradation processes, monitoring and control of these processes. In the theoretical part, it gives a brief overview of biodegradation processes, then focuses only on processes in which waste heat is produced. Mainly it focuses on the composting process, its stage, the ideal composition of the composting material, the composting methods, the control quantities and the metering devices. The practical part focuses on the improvement of the original bioreactor and the subsequent realization of the new bioreactor. The bioreactor is subsequently monitored using temperature sensors that describe the ongoing processes inside the compost using measured temperatures. The aim of the bachelor thesis is to connect the bioreactor with yurt, to realize thermal circulation and to control this circulation through the AMiNi system in order to achieve optimal heat recovery without negative effects on the course of biodegradation processes inside the bioreactor.
