Příprava, vlastnosti a využití tuhých biopaliv -- vybrané aspekty
 Klepárník, Jan
This PhD thesis deals with problems covering production of pallets and chunky wood, using small-scale technologies. There are particularly solved issues focused on fuel embedded energy and return on investment. Further, solid biofuels properties are discussed, and then the study of solid biofuels use in small hear sources was made being focused on the Czech Republic conditions. Particular attention is paid to problems with automatic pellet ignition. The last part is devoted to presenting partial results of a forwarder prototype, which is being solved currently.

Biopaliva ve formě pelet a krátkého kusového dříví
 Zamazal, Ondřej
The aim is to compare and evaluate the production of pellets and short piece of wood to its use for heating houses. Work presents the results of measurements of energy intensity of production short piece of wood per unit volume, compared to naturally drying metods and determination of bulk density at a given humidity. There was also found mechanical resistance, moisture and bulk density of pellets of different manufactures. Conclusion contains the proposal which describes technology for heating a house with use of both types of biofuels.
