Hydrothermal Conversion of Biomass
Vařejka, Tomáš ; Elbl, Patrik (referee) ; Lachman, Jakub (advisor)
The main aim of this bachelor thesis is to search for hydrothermal technologies for biomass conversion to improved energy carriers. First part includes contains introduction to biomass conversion methods and its suitability for different types of feedstock. The following part is dedicated mainly to hydrothermal conversion processes, their history, development over time, used technology, process and product characteristics and comparison with conventional thermochemical methods. Finally, the current state of technology is evaluated, possible future developments are outlined and current problems which are preventing wider application of this technology are descried.
Fast pyrolysis reactors
Fencl, Jonáš ; Lachman, Jakub (referee) ; Elbl, Patrik (advisor)
The aim of the bachelor thesis is a description of a fast pyrolysis process, its products and technologies based on the principle of fast pyrolysis using biomass as a fuel. In the first part of the thesis biomass and its energetical usage is described. The second part focuses on a charachteristics and history of pyrolysis. The third part describes fast pyrolysis process, convertion to bio-oil and important process parameters to obtain maximum liquid yield. Furthermore, single components obtained from the fast pyrolysis process and their usage is described. The fourth part describes types of fast pyrolysis reactors, their advantages and disadvantages. At last, the largest pyrolysis units operating in practice are described.
Off-grid homes
Plhal, Matěj ; Elbl, Patrik (referee) ; Baláš, Marek (advisor)
This bachelor thesis describes the principle of off-grid houses. It focuses on technological solutions of high-quality housing even without connection to public utilities. Primarily, it depicts suitable energy sources, heating options and water management. The practical part of thesis deals with the energy design of an off-grid home.
Design of a heating system for a family house
Rudišin, Lukáš ; Lachman, Jakub (referee) ; Elbl, Patrik (advisor)
The bachelor thesis focuses on the design of an ideal heating system for a selected object. The individual chapters theoretically analyze the used heating technologies, describe the building and its currently used heating system, propose alternative systems and evaluate them economically.
Energy mix development in the Czech Republic
Špaček, Michal ; Sitek, Tomáš (referee) ; Elbl, Patrik (advisor)
The topic of this bachelor thesis is the development of the energy mix of the Czech Republic. The first part is focused on concepts energy mix, energy security and the goals and priorities of state energy policy. Next part describes the development of the Czech energy mix up to present and in this part, the possible future development of the energy mix of the Czech Republic is described as well. In the last part, the energy mix of the Czech Republic is compared to the energy mixes of Slovakia, Poland, Germany and Denmark and the future development of these energy mixes is predicted as well.
Design of heating system for family house
Houzar, Filip ; Elbl, Patrik (referee) ; Lachman, Jakub (advisor)
This bachelor thesis deals with ways of family house heating. This thesis aimed to choose a suitable heating system for a specific family house. The first part of the thesis deals with a search of commonly used heat sources. This part contains a description of the work of these heat sources and their pros and cons. The following part introduces a specific family house, and the calculation of heat loss and annual heat consumption is performed. Then, three proposals are selected, for which the costs of their operation and return are calculated. At the end of the thesis, the proposals are compared and evaluated from an economic point of view. Based on this comparison, the most suitable proposals are selected, and the conclusions are commented on.
The workings of Autonomous Greenhouses
Formánek, Adam ; Kudela, Libor (referee) ; Elbl, Patrik (advisor)
This research work aims to concentrate information from extensive literature dealing with autonomous greenhouse related topics. The first part of the work is focused on basic concepts related to autonomous greenhouses. The second part explains an amount of concepts defining the logical apparatus and logical principles used in autonomous greenhouse design. Furthermore, this work deals with the physical aparatus of intelligent greenhouses, primarily its actuators. Finally it deals with autonomous greenhouse competitions, with focus on their conditions and logic.
Waste Gasification
Sedláček, Tomáš ; Elbl, Patrik (referee) ; Lachman, Jakub (advisor)
The bachelor’s thesis deals with the topic of waste gasification. The first part includes the definition of waste with the focus on municipal solid waste, its evaluation as fuel on the basis of its contents and properties, in this case the heating value. Eventually the waste is compared with other normally used solid fuels. The second part presents and describes the thermal processes applied to waste-to-energy technologies, where the gasification is explained in more detail, its final products, the content of contaminants in these products and their removal. The next part deals with technologies used for waste gasification. The last part deals with the issue of waste gasification in the Czech republic.
CO2 Sources and Emission Trading System
Valentová, Helena ; Sitek, Tomáš (referee) ; Elbl, Patrik (advisor)
This thesis deals with issues of carbon dioxide emissions, its sources and legislation related to emission trading. The first part of the thesis provides basic information about carbon dioxide and its production. The second part summarizes sectors that emit the most carbon dioxide. The last part describes the international legislation related to emission allowances and carbon trading.
Torrefaction Influence on Biomass Structure
Kojecký, Dalibor ; Sitek, Tomáš (referee) ; Elbl, Patrik (advisor)
This bachelor’s thesis is focused on the properties of fuels arising from torrefaction. The opening chapter is dedicated to general research into biomass. This chapter is made for familiarisation with biomass and types of its thermal treatment. The following chapters are dedicated to the torrefaction process. Specifically, a description of this technology and its influence on biomass. The last chapter documents how the individual parameters affect the torrefaction process.
