Optimization of Flat House Heating
Fodor, Ján ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This diploma thesis deals with the supply of heat in a particular block of flats in Brno. It deals with supply for heating and for hot water heating. The introduction gives information about the considerated building and also generally, but especially with regard to the current situation with consumption and heat supply. Subsequently, the thesis describes the individual possibilities of obtaining heat. There are mentioned classical heat sources as gas boilers, but also less commonly used as co-generating units or solar collectors. Furthermore, the work is calculating from the technical and economic point of view for heating options chosen by the investor. Finally, the work compares the options from viewpoint of benefits, budgets and returns of possible investments.

Comparison of Energy Circles from point of view Efficiency
Houdek, Milan ; Škvařil, Jan (referee) ; Lisý, Martin (advisor)
This diploma thesis investigates the combined production of power and heat from biomass. The main aim is to compare suggested energy circles in the light of their electric, general and economic efficiency. Introduction describes the basic terms and principles of energy utilization of biomass, combustion and gasification technology are described thoroughly. The main part contains suggestions and thermal calculations of energy circles. The thermal cycle with gasification chamber, combustion chamber and hot air turbine is proposed, than thermal cycle with gasification generator and cogeneration unit and finally Rankine-Clausius circle. In conclusion calculated results are recapitulated and the usability of proposed thermal cycles is assessed.

Technology solution for energy savings in industrial processes
Cyž, Antonín ; Miklas, Václav (referee) ; Konečná, Eva (advisor)
This bachelor thesis is a search of known technological solutions for energy saving in industrial processes. The first part contains a description of the methodology for the analysis of energy consumption in the company. The first part also solves some of the statutory obligations of an energetic area in companies. Then follows a description and possible use of individual technological devices. The theoretical part of the work evaluates and describes the possibilities to increase the energy efficiency of an industrial laundry. Finally, the economic – energy balance of a specific operation is analyzed, including the evaluation of the financial return on investment.

Integration of a co-generation unit to industrial power system
Kučera, Michal ; Holoubek, Jiří (referee) ; Drápela, Jiří (advisor)
This master's thesis deals with the integration of a mine gas burning cogeneration unit into industrial power system. The aim of the thesis is to design and evaluate different possibilities of integration the cogeneration unit into industrial power system. The first, theoretical part of the thesis discuss about cogeneration (combined heat and power). The technologies used for cogeneration are summed up as well as the possibilities of usage. The next part deals with the mine gas as the fuel for the cogeneration units. The lasts chapters of the theoretical part talks about terms for installation power source into industrial power system and about the possibilities of overflow of the electricity into distribution power system. The practical part deals with the installation of the 600 kW cogeneration unit into particular industrial power system. Four possibilities of operation mode of the cogeneration unit are design. At the end of the thesis the brief economical evaluation is accomplished.

Assessment of options to reduce energy consumption in industrial areal
Křesťan, Jan ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is assessment of options to reduce energy consumption in industrial areal belonging to Fritzmeier company. This thesis is divided into three parts. In the first part there is analysis of electrical energy and natural gas consumption in considered industrial area based on data from energy audit. The second part consists of short theoretical elaboration of cogeneration and cogeneration technologies, design of five variants of use of cogeneration units with combustion engine running on natural gas and evaluation of proposed variants. Third part of this thesis is about modernization of lighting system in small section of assembly hall. In this part parameters of new LED lighting system for selection are set, based on theoretical elaboration of LED problematics and five variants offered by specialized companies are evaluated.

Reconstruction the boiler room PBS Velka Bites
Filoušová, Natálie ; Fiedler, Jan (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with aggregate reconstraction the boiler room PBS Velká Bíteš and includes economic assessment of this reconstruction. The first part completes the earlier and old condition of the boiler room and ecological situation with insufficient cleaning of the combustion products. The short section is about czech legislation in area of emissions and emissions limits. Afterwards are analysed variations of the reconstruction and instalation of cogeneration unit too. Conclusion is comprised by economic evaluation of the variation of natural gas boilers and of natural gas boilers with cogeneration.
