40/5000 Fine particles produced by the stove
Škvařil, Ondřej ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This master thesis deals with problematics of fine particles produced during combustion in fireplace stoves. The theoretical part is focused on the analysis of the atmosphere, health consequences, solid pollutants, the formation of particles (origin), particle separation and how they are regulated by laws. Theoretical section of the thesis addresses analysis of biomass and its combustion. In the applied section are listed given methods of the particles measuring according to regulations, common errors during measurement and methods of identification of measured fine particles. Then follow specific measurements of the formed very fine particles produced by the SMPS method. Subsequently, the results of the measurement are evaluated and summarized in the conclusion.

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.

Burning pellets from non-wood biomass in boilers I
Knob, Jan ; Zejda, Vojtěch (referee) ; Brummer, Vladimír (advisor)
This bachelor’s thesis deals with combustion of non-woody biomass pellets in boilers. In the first part of the background research, biomass is generally described in terms of fuel properties, with a focus on characteristics determining its suitability for a direct combustion in boilers and undesirable emissions. In this context, planned legislative restrictions of boilers with a lower operating power are summarized. Furthermore the usage of the automatic boilers, and specific problems associated with combustion of non-woody pellets are described. Final part of the background research focuses on a composition of commercially available non-woody pellets and their production. Experimental part consists of fuel analysis determining the general properties of the biofuel - i.e. the water and ash content, essential content of elements, lower and higher heating values. Results of analysis are used to put together fuel lists of tested pellets. Conclusion of the experimental part discusses the influence of the pellet composition on the boiler functionality and emissions.

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.
