Energy balance of biomass heating plant
Žmolík, Václav ; Šen, Hugo (referee) ; Baláš, Marek (advisor)
This thesis deals with a design of a biomass heating plant combinating a Rankin-Clausius cyklus and a CHP unit. The CHP unit fuel is a biogas and the boiler fuel is a wooden chip. The adapted CHP unit regenerates feed-water of the R-C cycles. This design is technicaly and economicalty compared with the Rankin-Clausius cycle without feed-water regeneration by the CHP unit.

Technology Transfer Center
Kršková, Nikola ; Klimek, Karel (referee) ; Myslín, Jiří (advisor) ; Čuprová, Danuše (advisor)
This bachelor thesis is focused on a new building of office building in Telc within Technology transfer center. The shape of the land is trapezoidal and it is located in immediate proximity of the 1st class road, Třebíčská street. There are some others buildings of varios function near – college, administrative houses, houses of production, hall of residence. Its top view is rounded, defined by four ring arcs. The building is gaining mass with its height. It is situated on the northeast side of an estate, plot of land No. 5782/1. There is a car park in front of the building. There are a space laboratory for research and development of biological stuff, spaces for administration and management and biogas plant controling centre inside. The dominant space is an entrance hall with a staircase. The staircase is solved in Part D - architectural detail.

UTILIZATION OF BIOGAS IN TRANSPORT
Štylárek, Milan ; Zháňal, Lubor (referee) ; Vopařil, Jan (advisor)
Objective of this bachelor thesis is evaluating the possibility of utilization of biogas as an alternative fuel for combustion engines in traffic. Production and distribution of upgraded biogas is described as well as situation of its utilization in the world. This is followed by a comparison of situation in biomethan utilization in Czech republic and Sweden. There are explained barriers to commercial placing and its possible eliminating. In the end the model study of replacement of farm vehicle fleet for CNG vehicles is described.

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.

Losses in a pipe line because of the flow of mixed substratums
Vlasák, Bohdan ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
Introductory part of this thesis is aimed on theoretical description, principle and building of biogas stations, which require solution of many different problems. A specific group of the problems concern transport of mixed substrates of different concentrations both in and outside the area of biogas station. A major part of the substrate transport is done by pumping it in pressure pipeline. Experimental work consists of design and description of a measuring circuit. Graphic characteristics for water and gas loss levels are drawn from the measured readings. Multiples of pressure losses by flowage of substrates with different levels of dry basis are graphically expressed with a help of correction coefficients.

Biomethane production in biogas plants
Matoušek, Jakub ; Miklas, Václav (referee) ; Vondra, Marek (advisor)
This bachelor thesis deals with the production of biomethane in biogas plants. The introductory part presents the operation of the biogas plant, its inputs, components, and products. The main part of the thesis deals with the perspective of biomethane in the Czech Republic and Europe and progressive technologies for the conversion of biogas to biomethane. The basic principle, advantages and disadvantages of each upgrade method are given. Common technologies at the level of commercial readiness include high pressure water scrubbing, organic physical scrubbing, chemical scrubbing process, pressure swing adsorption and membrane separation. The mentioned methods of biogas upgrading are evaluated and compared with regard to their practical applicability in the Czech environment.

Bio-gas plant heat utilisation effectivity analysis
Šmarda, Marek ; Frič, Ondřej (referee) ; Pavlas, Martin (advisor)
This thesis focuses on the analysis of heat efficiency and effectiveness of the Vojtěchov biogas station unit. The material balances were developed in connection with biogas created in the cogeneration unit. The heat produced by the cogeneration unit is distributed to reactors and drying rooms. Pursuing the main goal of the thesis, the research of the complete heating balance for all months has been conducted. Additionally, a variety of options were assessed, to find the best solution of how to increase the effectivity of the heat. As for the final solution, two recommendations have been proposed in the thesis. The first recommendation lies in a better usage of low-level heat distributed to the secondary fermentor. The second suggestion deals with the amount of heat from cogeneration unit to the system. The result of the analysis is the final recommendation on how to increase the efficiency of the heat usage and potential impacts of the solution on the subsidy according to the KVET standards received in the given year.
