Agropellets Properties
Němeček, David ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
This thesis solves problems of combustion of agropellets and the advantages and disadvantages, which are connected with their application in combustion devices. In this thesis at first there is divided biomass, where it primarily concentrates on the plant biomass and it constitutes some used types, which are used to a fuel production. In the next part it solves problems of production of pellets, the advantages and disadvantages of this production and the advices for superior pellets. In the final theoretical part it solves combustion of this fuel. It is about properties of pellets, problems of combustion and this work also deals with emissions of combustion agropellets. In the last part the thesis engages in experimental detection of agropellets properties and plant biomass as such and subsequent comparison to wood biomass and tabular values.

Agropellets for House Boilers
Čaňo, Lubomír ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the characteristics of the agropellets and with their combustion in the house combustion units. In the introduction of the first part is described what the agropellets are and how they are produced. It is followed by a characteristics of the agropellets as a fuel and by their comparison to the other solid fuels. The end of the first part is dedicated to a combustion itself and the creation of emissions during it’s combustion. The second part of the bachelor thesis is focused on a practical verification of the characteristics of the selected agropellets as a fuel. It also includes the experimentally measured values of emissions during their combustion.

Verification of the use of agro pellets for heating
Muzikářová, Věra ; Musilová, Petra (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with agropellets and their combustion in terms of emissions and efficiency. It consists of two parts. The first part is theoretical, where the search of available types of biomass, production of agropellets and combustion principle is presented. The second part of the thesis is focused on experimental comparison of efficiency and emission class of boiler for various agropellets.

Solid Particle Emissions from AgroPellets Combustion
Svoboda, Marek ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This thesis is divided into two parts. The first part deals with defining the main concepts, properties of biomass and pellets. Further, the procedures for measuring agropellets properties according to valid standards are mentioned. The following is a selection of the raw materials for the production of agropellet, with the determination of their properties. The theoretical part closes background research emissions from combustion and emission standards for a solid fuel boiler. The second part is an experimental one, which determines the formation of solid pollutants in combustion of four types of pellets made from alternative sources. Here are the graphs of the gaseous emissions of each of them. At last there will be a comparison of emissions agro pellets with more widespread wood pellets.

Analysis of flue gas in automatic domestic boilers for agropelet
Minář, Marek ; Lisý, Martin (referee) ; Jecha, David (advisor)
The objective of the presented bachelor thesis is flue gas analysis during combustion of agropellets in automatic household boilers. Emphasis is placed on the description of biomass as a fuel, the ways of using biomass for energy purposes, alterations of biomass, production and properties of alternative pellets, automatic boilers and burners for combustion of specific fuel types. The end of the theoretical part is focused on standards and regulations for boiler operation. The practical part verifies the formation of emission on small sources of pollution and determines the concentration of solid and gaseous pollutants. The end of the practical part pursues with comparison of results with legislative requirements and calculation of boiler efficiency.

Energy use of agropellets
Zahnaš, Ladislav ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis deals with energetical use of agropellets made from agricultural residues especially in the terms of compliance with emission limits. First part is brief research of biomass in general and about methods of its processing. Second part deals with emissions from agropellets combustion and third part consists of an experiment where several types of pellets were burned, and their emissions evaluated.

Burning pellets from non-wood biomass in boilers II
Linda, Matúš ; Baláš, Marek (referee) ; Zejda, Vojtěch (advisor)
Bachelor thesis is divided into four main chapters. The first chapter deals with issue of combustion of agropellets in boilers. This section specifies types of pellets, their production and problems of combustion in boilers associated with formation of emissions. The second chapter specifies valid legislation and emissions limits. The third chapter describes fuel analysis of agropellets samples. This includes an analysis in order to determine the properties and chemical composition of agropellets resulting in determination of gross heat and calorific value. The fourth chapter evaluates agropellets influence on boilers and emissions creation on the basis of data and knowledge. The results are compared with data of other commonly used solid fuel found in literature sources.

Optimization of Agro-Pellets Boiler
Kurečková, Andrea ; Jecha, David (referee) ; Lisý, Martin (advisor)
The diploma thesis deals with optimization of pellet boiler for agropellets combustion. On the Czech market are mostly available boilers for burning wood pellets. Specially adapted agropellet boilers are pretty expensive. The work is divided into two main parts. The first part contains a research of agropellets, agropellets production and combustions of agropellets. The second part is experimental and describes the combustion test. It describes the measurement procedure, the necessary calculations and evaluation.

Agropellets for Combustion
Nejerál, Michal ; Lisá, Hana (referee) ; Lisý, Martin (advisor)
Agropellets are one of the alternative fuels which have been used very often nowadays. Therefore, this thesis deals with the use of agropellets as a fuel. It‘s focused on the generation of emissions during combustion. There are described properties of pollutants released during combustion and properties of agropellets. In a sample of selected fuels, the proportion of chemical composition of elements in the combustible and the calculation of their calorific value are experi-mentally determined. Furthermore, we found out the basic elemental composition of the flue gas, which was measured during combustion on the pilot unit.
