Increased power microturbines operating in indirect circulation
Polák, Luboš ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
Turbogenerator unit 100B TGU, produced in the First Brno Engineering Velká Bíteš a.s., works in Brayton indirect circulation. The aim of this work is the proposal to increase performance levels of technological unit in which the micro-turbine is applied. The work presents various ways to increase performance and efficiency of circulation. The possible options are compared with each of the technological and economic terms. Based on these criteria was selected variant feeding additional water into the circulation. For this design was the work of a mathematical model based on, which was established as the economic balance of the selected variants. The thesis also proposes a technological scheme, which is already incorporated the selected variant and an outline of the verification tests.
Biomass boilers
Netopilová, Petra ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This bachelor´s thesis concerns with the biomass boilers and the biomass as a renewable source of energy. The first part informs us about renewables sources of energy, concerns with biomass and with production of fuel from biomass. The second part describes the biomass boilers. Bellow it shows the possibillities of heating, which the todays market is able to offer us. It mainly deals with the posswibillities of haeting of biomass and compares the most economical boiler, which is used for different fuel. The calculating part is specialized in comparing of biomass boilers with gas boiler from economical standpoint.
Organic markers and compounds in PM1 aerosol in small town near Prague (Czech Republic) in winter 2016
Křůmal, Kamil ; Mikuška, Pavel ; Coufalík, Pavel ; Večeřa, Zbyněk
Contribution summarizes the concentrations of monosaccharide anhydrides, resin\nacids, methoxyphenols, monosaccharides, disaccharides, sugar alcohols, alkanes,\nhopanes, steranes and polycyclic aromatic hydrocarbons in PM1 aerosols in small town\nKladno-Švermov in winter. According to concentrations of organic markers, the\nidentification of emission sources in Kladno-Švermov is discussed.

The processing of biomass for direct combustion
TOMÁŠEK, Petr
The aim of this work is to create an overview of the possibilities of using the biomass for energy purposes and to assess various treatment technologies of biomass for direct combustion. It was performed the consumption monitoring of pellets in a family house newly insulated and an assessment of the pellet boiler. As fuel for heating of the house were used white wood pellets made from clean wood and wood waste, without additives. For calculation the consumption of pellets and an assessment of the boiler were used data from the heating season 2011/2012. Finally, a comparison is made of pellets and other fuels for heating the object.
Possible utilization of grass material
KOBERNA, Daniel
The objective if this degree work is creating a survey of possible uses of surplus grass material which is caused by animal farming reduction and by bringing the ground in less fertile areas of our country to a standstill. In the work possible uses of the grass are described, especially its use in the energy industry as a fuel source for the production of heat and biogas. Classical usage of the grass material as a food source for livestock or for the production of compost is described here as well. Examples are shown there of energy kinds of grass, which seems to be a promising renewable resource of biomass for favourable economic results. The harvest of the grass material and its consequent prossesing is done by production lines, that is why a survey of such lines and their economic figures connected with the operation of these machines is also included in this work. The economic part of this work contains many formulae that can be used for counting out all the costs connected with the operation of the grass harvest machine and for evaluating the effectiveness of the return on investment into this machine
Legal aspects of usage of Renewable Energy Sources
Szennai, Tomáš ; Štěpánek, Petr (advisor) ; Černý, Pavel (referee)
This Bachelor Degree Final Paper is supposed to provide the reader with complex overview of specific legal regulation of use of renewable energy sources. The main focus is set on Czech legal provision. However basic description of law of the European Union in the respective field, as a corner-stone for the one of the Czech Republic, is also contained. Additionally former provision that regulated usage of RES before admission of the Czech Republic into the EU is included. The very last chapter of the paper offers brief study of most recent European directive concerning the respective field.
