Comparison of methods of determination of LHV and HHV
Jahn, Jiří ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This bachelor thesis is focused on the comparison of the accuracy of the determine of the higher heating value and lower heating value using the equations. The calculation is based on the contents of samples in the fuel, ie from the data obtained by ultimate analysis. Higher heating value and lower heating value of each fuel type was obtained by calorimeter measurement and considered to be the exact value of the fuel. The output of the work is the evaluation of suitability and accuracy of the examined equations and introduction equations appropriate for biomass.

Fuel Properties: Proximate Analysis of Solid Fuels
Kučera, Ondřej ; Elbl, Patrik (referee) ; Musilová, Petra (advisor)
The bachelor thesis deals with the use of biomass as an alternative energy source and proximate analysis of solid fuels. In the theoretical part there is a research on energy utilization of biomass and a proximate analysis of solid fuels. Individual methods of determination of proximate analysis are described in detail, namely determination of water, ash and volatile combustible content and determination of gross calorific value. The practical part presents results of analysis of selected locally available plant biofuels. The methods of proximate fuel analysis have been successfully applied.

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.
