Composition of Municipal Waste
Straka, David ; Musilová, Petra (referee) ; Elbl, Patrik (advisor)
This bachelor thesis deals with the composition of municipal and mixed municipal waste. Introduction of the research part deals with the composition and properties of waste. In the next section, the waste is considered as fuel and compared with conventional solid fuels. The conculusion of the research part is devoted to the research of the waste composition from selected incinerators adn foreign countries. The compulational part of the thesis deals with the determation of energy properties of the waste.

Design of syngas cleaning by wet scrubber
Musilová, Petra ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
Gasification is a process which produces gas of low heating value, however, generated gas contains several pollutants. This thesis is dealing with the issue of purity and cleaning of generated gas. Theoretic part of thesis consists of research, describing the very process of gasification itself, mapping of possible pollutants appearing during gasification and particular ways of purifying gas, looking in detail at wet scrubbing with several scrubbing liquids. Further, it looks into proposition of conditions for wet scrubbing and balance of scrubbing liquids. Next part deals with calculation of purifying line. Main goal of calculations, is to determine the length of the pipeline, transfering polluted gas from the gasifier to the filter for elimination of solid particles and wet scrubber. Key aspect of length calculation was the input and output temperature of the gas, determined by characteristics of the filter. Calculation for wet scrubber istelf is also included, to detremine if the output temperature of the scrubbing liquid after the passage of the gas needs to be modified by additional cooling or heating. For experimental purposes, syngas generated by gasification of biomass, is gathered from the atmospheric gasifier Biofluid 2. Experiment itself inquires into the purity of the gas before and after the passage through solid particles filter and through the wet scrubber. The purpose of this thesis is to determine the chemical composition of gas before and after wet scrubbing, the difference of composition of tar gathered from purified and nonpurified gas and using gathered data to evaluate the effectiveness of wet scrubbing.

Proposals for action elimination of heat loss in buildings
Vašulka, Tomáš ; Musilová, Petra (referee) ; Baláš, Marek (advisor)
This bachelor thesis is about measures leading to heat loss reduction for the model family house. In the research part, available methods and materials are summarized which can be used in thermal insulation of perimeter structures. In the next part, principle of recuperation unit is described which serves for decrease of heat loss by ventilation. Next, the calculation of heat loss is described with heating costs of the house. In the next part, several thermal insulation measures are proposed. In the end, the insulation measures are compared economically.

Energy use of biomass
Musilová, Petra ; Brázdil, Marian (referee) ; Baláš, Marek (advisor)
The objective of this bachelor’s thesis is a research study of biomass use in energy industry with main focus on electric energy production. This thesis primarily concerns with biomass properties, biomass processing technologies and the application of such technologies in the Czech Republic. The first part of this work consists of biomass definition and its division. The next part deals with biomass energetic properties and following is a familiarization with cogeneration (the combined use of heat and power to create electricity). Furthermore this thesis analyses individual technologies used in electricity production. The last part focuses on heating plants, power stations and biogas plants, which use biomass and on charting these specific units in the Czech Republic.

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.

Verification of the use of agro pellets for heating
Muzikářová, Věra ; Musilová, Petra (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with agropellets and their combustion in terms of emissions and efficiency. It consists of two parts. The first part is theoretical, where the search of available types of biomass, production of agropellets and combustion principle is presented. The second part of the thesis is focused on experimental comparison of efficiency and emission class of boiler for various agropellets.

School, the Foundation of Life – a Complex of Educational Buildings in Ostrava, Cerna louka
Musilová, Petra ; Halfar, Jiri (referee) ; Mikulášek, David (advisor)
Assigment of the Diplom Project was to design complex of school buildings in the Ostrava city, on Black Maddow. Design should be based on the winning project from Maxwan architectural studio. They won the urbanistic competition in this area. I decides to devide funktions to the 3 different buildings – Kindergarten, Primary school and Lyceé in a one builging and the multifunktional sport hall. Kindergarten ist placed in the park, on the riverbank. Primary school and Lyceé are connected in one building, which is situated in the ring of buildings arround the Black Maddow. Parter under the building is public and building is situated on the most frekvent place, where the footpath are crossing. Near the school building is designed a sport hall, which is not just for school use but also for public.

House energy solutions using renewable energy sources
Sabo, Martin ; Musilová, Petra (referee) ; Poláčik, Ján (advisor)
This bachelor thesis discusses the role of renewable sources of energy in energetics of a family house and technologies providing this possibility. Special care is given to power production, heating and air conditioning. The issue of low-energy and passive houses is described in the beginning of the thesis, leading to acknowledgement with different types of energy sources. Analytic part of the thesis contains general information about ways of heating and power production using renewable sources of energy. Different ways of ventilation are introduced and suitability of specific technologies assessed. The practical part describes design of ventilation and heating unit in an experimental house.

Fuel properties: Determination of moisture solid fuels
Tretera, Michal ; Musilová, Petra (referee) ; Lisá, Hana (advisor)
This bachelor's thesis deals with the determination of moisture content in solid fuels. First part contains classification of solid fuels, proximate analysis of solid biofuels and a research of methods for determination of moisture content in solid biofuels. Description of impacts of the moisture content on fuel is included in the proximate analysis. Second part of the thesis is experimental. Thirteen solid biofuels and one solid recovered fuel were measured to obtain their moisture content. The methods used to determine the moisture content include four different drying methods and a xylene distillation method. For each method there are details of the procedure and a summary of the results.
