Solar systems utilization for family house energy demand
Šamanová, Jaroslava ; Toman, Filip (referee) ; Sitek, Tomáš (advisor)
Solar systems are more and more common part of residential houses. Main reason for this, is that solar elements are state-supported with subsidies, which is reducing payback time of these investments. At the same time, the prices for these systems are dropping. The state support is connected with effort to reduce dependancy on non-renewable energy sources, e.g. coal powerplants, which are polluting atmosphere. State administration i salso the reason for large scale solar powerplant constructions, which are, according to some opinions, misshaping the landscape and covering large areas of sometimes fertile land.
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.
Fine particles and air-cleaning
Bírošíková, Martina ; Sitek, Tomáš (referee) ; Poláčik, Ján (advisor)
This bachelor thesis deals with issues with fine and ultrafine particles, also called particulate matter, which is strongly associated with enviromental problems and negative effect on human health, especially cardiovascular diseases. The aim of this work is to describe the formation and characteristics of fine particles produced by biomass combustion. The experimental part firstly explains funcional principle of used devices and then compares measured concentrations of ultra fine particles produced by combustion of spruce and beech wood. In the end, several posibilites how to eliminate the air pollutants are presented.
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.
Heat recovery from waste water
Paulíková, Kateřina ; Sitek, Tomáš (referee) ; Toman, Filip (advisor)
The aim of the Bachelor’s Thesis is to discuss the view of wastewater as a source of thermal energy. The thesis is divided into three main chapters. The first chapter aims to acquaint with the issue of wastewater. The analysis of systems for heat recovery from wastewater is summarized in the following chapter. Also there is a focus on systems installed directly at the generation of wastewater, inserted into the sewerage pipes and finally the creation of thermal energy in wastewater treatment plants. All mentioned systems are built to be economical and ecological efficient as possible. Finally, the last chapter includes an overall evaluation of the systems.
Design of equipment to reduce emissions of solid pollutants
Barybina, Alina ; Sitek, Tomáš (referee) ; Baláš, Marek (advisor)
This bachelor thesis consists of the theoretical and the practical part. In the theoretical part (chapters 1 and 2) the properties of PM, legislation in the Czech Republic, principles of separation of particles and different types of separation devices are described. In the practical part in the chapter 3, a design of a filtration system for separating PM from the flue gas from three biomass boilers was made.
Utilization of carbon dioxide in power engineering
Svoboda, Kryštof ; Sitek, Tomáš (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with the use of carbon dioxide as a source of energy in the form of carbonaceous fuels. The first part describes the possibilities of carbon dioxide capture and its subsequent storage. The second part is dedicated to the conversion of carbon dioxide to carbonaceous fuels. In the third and final part of the thesis, these fuels are then evaluated for their utilization and compared with commonly used fuels.
Heating the House by a Heat Pump
Najbrtová, Zuzana ; Sitek, Tomáš (referee) ; Toman, Filip (advisor)
The bachelor thesis deals with the issue of heating a house by a heat pump. It has two parts: The theoretical part describes the principle of heat pump and its types, according to the source of low-potential energy used. The practical part outlines the dimensioning of the heat pump, based on the calculation of the heat loss of the selected building. Finally, the economic-technical comparison of the heat pump and the gas boiler is drawn.
Composition and Energy Use of Municipal Waste
Anisimov, Valerii ; Sitek, Tomáš (referee) ; Elbl, Patrik (advisor)
This bachelor thesis deals with composition and energy use of municipal waste. Properties of municipal waste are described in the first chapter. The second chapter compares composition of waste in different municipalities. There is description of waste to energy technologies in the third chapter. The last chapter describes incineration plants in Czech Republic.
