Higher Heating Value of Sewage Sludge
Mikluš, Michal ; Bělohradský, Petr (referee) ; Houdková, Lucie (advisor)
The thesis is focused on problems of thermal treatment of sludge from wastewater treatment plants. The main objective is to establish a formula for calculating higher heating value (HHV) and lower heating value (LHV) of sludge based on its chemical analysis. The work is divided into two main parts: The theoretical part deals with the characteristics of sludge, thermal treatment of sludge, it isn´t omitted higher heating value and lower heating value. The main topic of a practical part is formulation of eguations for HHV and LHV calculation. Chemical analysis of sludge samples were supplied by TÜV NORD Czech s.r.o., together with the values of HHV and LHV. The calculations were verified by the program MINITAB.

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.

Condensing technology and flue gas
Müller, Jan ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This thesis is developed as a proposal for heating for a primary school and kindergarten in the region of Brno-countryside. For the insulated building, a combination of heating and air-conditioning is proposed. The concept is designed so that the air-conditioning preheats the exterior air and the heating system warms the incoming air to a comfortable temperature. For the required thermal performance, sources of heat (for gas and pellets) and a layout solution for the boiler room is designed. Drainage of combustion products is proposed for both solutions. The project solution is per the extent of the construction permit. The theoretical part is linked with the practical part through the condensation boilers, their function and division, and drainage of combustion products. The experiment for the given topic was conducted on the drainage of combustion products. The pressure loss of the reverse knob was determined in relation to the flow rate of air in the condensation boilers as this loss is essential in assessing the drainage of combustion products.

Impact of Biomass Storing on Heating Value
Černý, Michal ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The main aim of my bachelor´s work is the experimental verification of the landfill impact on the parameters biomass. The first part deals with definition, the formation of a basic biomass division. In the next section we find the issues concerning the burning, fuel composition and emissions during combustion. The last part deals with the influence of climatic conditions on the biomass degradation. In the experimental part were measured calorific calorimeter. The result was that, after a measured period of five months to avoid significant degradation of the fuel.

Sludge disposal from wastewater treatment plants in case of transport and sludge incineration
Petříčková, Alena ; Šomplák, Radovan (referee) ; Frýba, Lukáš (advisor)
The bachelor´s thesis in theoretical part deals with the disposal of sludge with respect to legislation, method of sludge treatment and drying technologies. This part is also dedicated to traffic connected with sludge. The practical part includes the calculation of combustion heat and calorific value. This section is also deals with summarization production of sludge and sludge treatment, analysis of these data. This part also includes an overview of the mass flow of sludge across the Czech Republic at locations with extended powers.

Measurement Uncertainties Analyze in Gas Industry
Dominik, Jan ; Zuth, Daniel (referee) ; Vdoleček, František (advisor)
This bachelor thesis is tackling measurement uncertainty problems with gas metering. It is specially focusing on a new prototype gross heating value indicator, which was tested directly on the pipeline. This measurement results are compare with standard volumetric flow indicator and determined measurement uncertainty for the distribution partners.

Comparison of properties of alternative pellets
Jansa, Oldřich ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
This thesis deals with the alternative pellets and the means of production from raw material to final customer. The theoretical part deals with different techniques and manufacturing technologies used. Furthermore, the work deals with Czech and European legislation in the field of fuel pellets. The practical part deals with measuring and comparing the properties of selected standard pellets.

Utilization of unconventional biomass for energy production
Boumová, Markéta ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
Tato diplomová práce se zabývá netradičními druhy biomasy využitelnými v České republice a Španělsku a jejich srovnáním. V prvních kapitolách jsou popsány netradiční druhy biomasy, mezinárodní projekty, smlouvy a legislativa. V následujích kapitolách je rozbor netradičních druhů biomasy zejména vznikajících z potravinářského průmyslu každé země s detailním rozborem a srovnáním zbytků z průmyslového zpracování slunečnice a oliv. V závěru je uděláno celkové srovnání těchto druhů biomasy České republiky a Španělska z aspektů výkupních cen, výhřevností, vlhkosti a množství popelovin.

Study of reaction to fire tests for thermal insulating materials
Krivda, Antonín ; Novák, Vítězslav (referee) ; Sedlmajer, Martin (advisor)
This bachelor thesis deals with thermal insulation, it is fire resistance and reactions to fire. The thesis also approaches the testing of thermal insulation materials. In detail, it focuses on the Small flame test, Calorific value determination and the Flameproof test. The test methods were performed on insulators based on polystyrene and mineral wool. The literary research focuses on the fire safety of buildings that have been already insulated.

The Effect of Biomass Storage on the Fuels Parameters
Zlevorová, Tereza ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This thesis investigates the effect of storage on the basic properties of fuel. The first part summarises basic knowledge of biomass, its properties, storage methods and related problems. This is followed by an experimental part, which aims to investigate predicted decrease in the calorific value and volatile matter of materials due to spreading degradation. The experiment is based on repeated measuring of the properties of samples stored for thirteen weeks at three different temperatures and moistures. The results are graphs that show a decreasing trend in most cases. They also show differences in the extent and rate of degradation depending on the type of material and the ambient conditions.
