Polyfunctional zone MOŘICE okr. Prostějov
Janovská, Tereza ; Vojtová, Lea (referee) ; Dýr, Petr (advisor)
The task of the diploma thesis is to prepare an architectural-urban study of a large multifunctional complex of the AGRISPOL company in the village of Mořice. The proposal is to have a wide scope, design of biogas plant, storage facilities, silos, internal roads, accommodation and recreation. The agricultural centre owns four agricultural sites, Mořice, Vitčice, Vrchoslavice and Pavlovice near Kojetín. The topic of the pre-diploma thesis was the agricultural centre Vitčice. The main idea of the thesis was to design efficient communications, layout and arrangement of the biogas plant, revitalization of garages and workshops, design of storage halls for the purposes of the cooperative or for rent. The eastern part of the plot is designated for short-term housing and senior housing in the proposed nursing home, supplemented by services such as manicure, pedicure, hairdresser. These two units are divided into almost two identical buildings that resemble a hockey stick in shape. The combination of these two shapes has created an inner courtyard which serves as a garden/park for the adjacent accommodation units. The park will be freely accessible to the public. The capacity of the nursing home is 16 accommodation units. The units include a hallway, private bathroom and a living room with kitchenette. The capacity of the adjacent apartment building with an adjacent multifunctional part is 8 flats of 1+kk size and 9 flats of 2+kk size. The apartments are designed as starter housing for young couples or for accommodation of AGRISPOL employees. It is a form of short-term housing.

Modern Biogas Station as Part of "Smart Regions"
Horák, Jakub ; Pavel,, Milčák (referee) ; Lisý, Martin (advisor)
This thesis deals with the design of computational model of a biogas plant and its use in the concept of intelligent region with focusing on district heating and cooling network. The introduction contains review of technology used in the biogas plant. This review covers the description of modern biogas plants and determination of the energy and technology parameters for computational model of biogas plant. The next part of thesis describes analyze of the dynamics of the operation and the possibilities of using waste heat from biogas plant. The last and also the most important part is based on design of computational model of a biogas plant and design of connection of a biogas plant to the district heating and cooling network.

Biogas Plant Telč
Kundrák, Karol ; Klimek, Karel (referee) ; Myslín, Jiří (advisor) ; Čuprová, Danuše (advisor)
This proposal called "development of VTP and CTT Vysočina” counts with the intention of building a science and technology park , which under different conditions will test composition of crop input parameters for biogas production and energy utilization . The aim of the thesis was to design a building of Science and Technology Park and laboratories which has a very simple and logically arranged disposition but also representative exterior which creates a strong industrial character . VTPL building is designed as one and partly two-storey building which consist of one two-storey blocks and three single-storey blocks, which gradually shrink and copy the triangular shaped site. The building was designed in a way to ensure a smooth transition of materials from technological objects into the VTPL building and then to individual laboratories and offices . To achieve expression of industrial building was covered in aluminum composite siding.

Energy yields per one hectare of land in the South Moravian Region
Plášek, Tomáš ; Bayer, Robert (referee) ; Jandová, Kristýna (advisor)
This bachelor thesis compares methods of producing elektricity in biogas plant, in thermal power plants by burning biomass, in solar power plants and compares it with production of energy of fuel cells and the energy from biofuels, like biodiesel and bioethanol. It compares the energy yields of different energy production methods and evaluates their advantages and disadvantages. It compares the energy content of these fuels by model vehicle range.

Integration of a technology for digestate thickening in a biogas plant
Miklas, Václav ; Touš, Michal (referee) ; Vondra, Marek (advisor)
This diploma thesis is mainly focused on the digestate thickening in a biogas plant. First, overview of the biogas technology in the Czech Republic is presented. Furthermore, problems with waste heat utilization and processing of fermentation residues (digestate) are described in more detail. Based on the research, multi-stage flash (MSF) evaporation was chosen as the technology for the digestate thickening. The main part deals with the integration of the chosen technology into a biogas plant process. The programming language Python was used to simplify the given task. In the preliminary stage, a complex mathematical model of a biogas plant was created, focusing particularly on the mass and energy balances. Subsequently, a computational model of the MSF evaporator was programmed. A procedure for the integration was suggested using the sensitivity analyses. Additionally, the model of a biogas plant was extended with the MSF evaporator. The key outcome of the thesis is a technical-economic analysis in which the impact of digestate transport price and electricity feed-in tariff on payback period is investigated. The results suggest profitability of MSF evaporator for biogas plants without subsidized feed-in tariff. Contrastingly, installation of MSF evaporator in older biogas plants with subsidized feed-in tariff can be economically viable only in cases of significantly longer transport distances.

Design of equipment for thermo mechanical pre-treatment of biodegradable waste
Kolařík, Ivo ; Jedlička, Filip (referee) ; Beňo, Zdeněk (advisor)
The main objective of this master’s thesis is to develop design equipment for thermomechanical pre-treatment of biodegradable waste. An important aspect of the design is taking into account current legislation, sanitary conditions for determining the pre-treated biodegradable material, which also serves as a raw material for biogas production. So the device will be used to monitor the impact of thermomechanical pre-treatment of biodegradable waste for biogas recovery. The following describes the processes of anaerobic decomposition of biodegradable materials and technology, whose main task is intensification of anaerobic decomposition of organic materials. The theoretical work are given various methods of processing and utilization of biodegradable wastes, focusing on kitchen waste and sludge from sewage plants. The next section describes the various factors that may affect the stability of the process of biogas generation. This also results in yield and chemical composition of biogas. A key part of this master’s thesis is to develop technical documentation and an approximate calculation of the hot slurry.

Fermentation remainder treatment in a biogas plant
Budín, Oto ; Touš, Michal (referee) ; Vondra, Marek (advisor)
This diploma thesis deals with dewatering technologies of fermentation residues from biogas plants and aims to design an integration of selected technology into the biogas plant. Fermentation residues (or digestate), which are a by-product of anaerobic biomass fermentation in biogas plants, contain a certain amount of nutrients and are usually used as agricultural fertilizers. However, the high-water content in digestate and the associated low nutrient concentration increase the cost of its storage and transport. Dewatering of fermented material could help reduce these costs. The main part of this work included the design of an integration of the selected dewatering technology into the biogas plant – its placement in a process, an addition of necessary appliances, the influence on material and energy flows. In this case, the fermentation residues are processed in two phases. First, a separation of the solid and the liquid fraction by a screw press. The second step is to thicken the liquid digestate by evaporation in a multistage evaporator. Evaluation of the design of a dewatering technology, including its impact on the economy of the biogas plant, is also part of the diploma thesis.
