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.

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.

Ultrafine combustion particles
Sitek, Tomáš ; Skála, Zdeněk (referee) ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with issues of fine and ultrafine particles formation during thermal decomposition and combustion of biomass. An introduction is devoted to a utilization of biomass as fuel. A following part describes the gas products emerging generally during combustion process. A current emission and air pollution situation in the Czech Republic as well as the health impacts of solid pollutants on human are also mentioned. Within an experimental measurement three basic factors that have impact on fine particles formation during combustion of beech wood (i. e. oxygen content in combustion atmosphere, type of the sample and size of the sample) were thoroughly analyzed. Attention was paid to a progress of thermal decomposition and combustion of sample with respect to the particles formation. Finally, a measurement of fine particles amount was accomplished in a real boiler successively with four different biomass pellet types.

Solid fuels boilers
Sitek, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor thesis is focused on solid fuel heating of a detached house. The first section describes most common solid fuels, their composition, characteristics and combustion principle. Following section is about solid fuels boilers with their operation description and most common designs and types. In the end economic and user aspects of four selected boilers are described, such as acquisition and operation costs, operation comfort etc. The resulting graph of total costs over fifteen years can be used for general comparison of selected boilers.
