Processing and utilization of by-products of brewery operations for energy purposes
Foltis, Marek ; Malaťák, Jan (advisor) ; Bradna, Jiří (referee)
The diploma thesis called Processing and using of co-products from brewery for energetic purposes. The thesis concerns it self with analysis current situation on field of processing waste from brewery industry. The thesis is focused on possibility of using brewery waste for energetic purposes. The thesis is divided in to two parts. First part features literature research of the topic, using all available resources. Second part features real data from element analysis done on samples of brewery waste and calculation of main characteristics of brewery waste. All calculations concerns them self in using brewery waste like substitution for fossil fuel. Goal of second part of thesis also is evaluate possibility of using brewery waste to make brewing more efficient.

Heat-emission characteristics of the energy compost for small combustion plants
Bučinský, Václav ; Malaťák, Jan (advisor) ; Bradna, Jiří (referee)
The aim of this thesis is to get acquainted with the problems of biological and energetic use of compost. Emphasis is placed on the technology and features of the energy compost, which is intended for combustion, gasification or pyrolysis. The work presents characteristic properties and composition of solid biofuels. There are characterized pollutants, including hazardous properties. There are also mentioned legislative conditions, particularly in the area of emission limits and fuel quality in terms of air protection. Further, a description of the main design features of a small grate combustion plants.
The second part of the thesis contains a comprehensive analysis (elemental, stoichiometric, heat emission and economic) of selected samples of solid biofuels. Based on the analysis, the samples were evaluated and assessed whether they comply with emission standards and fuel quality requirements in terms of legislation. Analyzed fuels have been characterized and it has been proposed the use of appropriate energy for small combustion facilities.

Proposal for a technological line for production pellets from biomass
Holub, Ondřej ; Malaťák, Jan (advisor) ; Bradna, Jiří (referee)
The aim of this thesis is to introduce the proposal of the technological line (from the initial intake of the essential raw material to the final product) for the production of pellets from biomass. For better understanding, this work presents the characteristics of various types of biomass and its most common use in everyday life with the focus on specific kinds of pellets (standards, certificates, protective marks both Czech and foreign). Further it informs about the issue of classification, quality frameworks and specification of solid biomass for energy purposes and characteristics associated with the legislation, technologies, techniques and legislative conditions of use of waste biomass. It also compares the different types of pellet samples in the relation to the most important aspects (contents of substances, ash, calorific value etc.) and in what price range they appear in our market. Subsequently, on this basis, the assessment of the technical and economic aspects of the proposed solutions is carried out and the major physical chemical features of biomass are described.
