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.
