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.

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.

Energy use of biomass
Musilová, Petra ; Brázdil, Marian (referee) ; Baláš, Marek (advisor)
The objective of this bachelor’s thesis is a research study of biomass use in energy industry with main focus on electric energy production. This thesis primarily concerns with biomass properties, biomass processing technologies and the application of such technologies in the Czech Republic. The first part of this work consists of biomass definition and its division. The next part deals with biomass energetic properties and following is a familiarization with cogeneration (the combined use of heat and power to create electricity). Furthermore this thesis analyses individual technologies used in electricity production. The last part focuses on heating plants, power stations and biogas plants, which use biomass and on charting these specific units in the Czech Republic.

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.

Increasing of electricity production in BGS using ORC cycle
Beck, Michal ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
Objective of this Master’s thesis is to make search about generation and use biogas, with focus on cogeneration and to make search about possibilities of increasing the share of production of electricity by cogeneration from biogas. This final work has also the task to summarize possibilities of increasing the share with ORC cycle and to evaluate pros and cons of this use. Main part of this work is dealing with own design of increasing production of electricity with cogeneration from biogas in biogas station with ORC cycle and comparing this modification with steam engine.

Energy audit of biogas station
Verner, Tomáš ; Formánek,, Marian (referee) ; Horák, Petr (advisor)
Master's thesis deals economy evaluation of biogas station. As evaluating mechanism was elected energy audit. It tries to show all effects and economy and energy influences. Output evaluation recommend the best option of project. Master's thesis also solves project documentation. It contains implementation drawings and scripts. Thesis thinks about global reason production of electric energy in biogas stations.

Hranice – redefinition of urban structure
Uherková, Ivona ; Ryšavá, Hana (referee) ; Ponešová, Barbora (advisor)
The diploma thesis Park and Ride deals with the design of a car park in the town of Hranice, which is known mainly for its important transport train node and Hranice Abyss. The city now suffers from the high intensity of car traffic in the city center due to insufficient street network. This network is disrupted by a four-lane road that was built in the 1980s and cut natural transport links. The abolition of the four-lane road, which is now lacking in transport services, releases a large amount of development area, which is primarily used as an agri-recreational area. Part of this green belt is the parking house, which prevents the entry of surplus cars into the city center. The parking house is a new transport hub of the city, which also includes elements of alternative transport - transfer to public transport or bicycle, which makes it possible to create a city center pleasant for pedestrians.

Design of Biogas Cleaning Technology
Šrámek, Zbyněk ; Milčák, Pavel (referee) ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
Thesis aims to design suitable technology for biogas treatment so that its output can be used as a fully equivalent fuel for vehicles. First part introduces reader into an area of biogas treatment. Second part describes in detail chosen method, technology of membrain separation. In third part, current conditions in Czech republic were discussed. Fourth part adresses the aplication of membrane technology into existing biogas station via side-standing reaserch container. The end of the thesis is focused on selection and proper desing of blower, which will be transporting raw biogas from biogas fermenters into research container.
