Utilization of biomass for the energy purposes
Romanová, Kristýna ; Ing.Ondřej Kosík, Ph.D. (referee) ; Flodrová, Dana (advisor)
The theoretical part of work focuses on the issue of biomass used for energy purposes, in particular agricultural waste, which can be used as a substrate for biogas station. Furthermore, examines the composition of polymer substrates, which affects most biogas process. The aim of this work was to measure each sample of enzyme activity of biomass, which is used as a raw material for biogas plants.

Forming of solid pollutants from biomass
Havlínová, Denisa ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor‘s thesis is divided into two main parts. The first part is research and deals mainly with biomass and pollutants. In this section, we will find a two-dimensional distribution of biomass, a comparison of fuel forms and a discussion of basic pollutants with a focus on solid pollutants. The second part is experimental. It starts with a fuel laboratory, where the water, ash and heat content of the biofuels examined is determined. The following is an investigation of the dependence of the PM formation on the properties of the biomass, which was measured by the measurement of these PM by the filters in the collecting device, while the examined biofuels were gradually burned on the fireplace insert.

Press design for paper briquettes
Kočař, Jiří ; Rebenda, David (referee) ; Dvořáček, Jiří (advisor)
The bachelor thesis deals with an engineering design of a press briquette machine, which process refuse of paper. This refuse is used for production of paper 's, eventually paper-sawdust 's briquets. The first part contains analysis of options of processing garbage, current machines producting briquets and their versatility. The second section is focused on a final design of a pressing machine and a general description of it's parts.

Automatic boiler for biomass pellets
Sklenář, Vít ; Štelcl, Otakar (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is the research of automatic boilers for biomass pellets and their burners, design of automatic boiler for biomass pellets which include calculation part and drawing part and technical-economics assessment for building in the end. Thesis is divided into four main parts. The first part deals with general information about pellets, automatic boilers for pellets, burners and the standard for boiler. In the second part the pellet boiler is calculated. In the third part the automatic pellet boiler is designed. The fourth section compares three possible variants. Comparison is done for economics and the user.

Solid fuels boilers
Šmejkal, Petr ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with burning solid fuels in boilers used for house heating. In the first chapter, the individual kinds of solid fuels are described in light of their composition, properties, means of their energetical application and ways of adjusting them to a form proper for combustion. In the second chapter, the individual types of solid fuels boilers are described. The last chapter deals with comparision of several specific boilers in light of their purchase price and operating expenses.
