Use of agromaterials for heating houses
Kudová, Anna ; Lachman, Jakub (referee) ; Baláš, Marek (advisor)
This bachelor thesis focuses on the biomass usage for energy generation in particular on comparison to wooden between hay pellets. First part is dedicated to fuel attributes, solid fuel boilers and pertaining legislation. Second part deals with an experiment which compares burning of both types of pellets in an automatic hot water boiler. The proximate analysis of fuels is conducted as well.

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.
