Utilization of compressor waste heat into the district heating system by means of an absorption heat pump
Aranguren Campos, Fabian Alexis ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
With the growth of energy consumption and the optimization of industrial processes worldwide, new energy sources have been explored and investigated. Waste heat is a potential source for the generation of electricity and heat. This heat can be reused at different stages of industrial processes by using absorption heat pumps, which transfer thermal energy from a location with a lower thermal potential to a location with a higher thermal potential. This research work is basically focused on the evaluation of different absorption heat pumps implemented in the SAKO Brno incineration plant. To carry out this purpose, a bibliographic review of this technology has been carried out worldwide, then the mass and energy balance in the compressor is presented, from which the waste heat to be recovered with the pump will be obtained. Using the EES software, the mass and energy balance of the selected pumps is performed, then the amount of heat and electrical energy generated by the plant when implementing each of the pumps is shown, and finally the economic analysis is presented The design and implementation of a heat exchanger in the system is also included as an essential part of improving operation. The best option arises from the highest operational efficiency at the lowest possible cost.
Heating options of a house
Veselý, Přemysl ; Baláš, Marek (referee) ; Toman, Filip (advisor)
The bachelors thesis deals with the topic of heating possibilities of family houses. The work is divided into two parts. The first chapter deals with the search for heat sources used in local central Europe conditions. The practical part deals with economic calculation and economic assessment for used heat sources. Its aim is assess the correct economic intensity of resources used for different family houses, divided by heat loss.
Design of heat source for heating a family house
Kotráš, Pavel ; Lachman, Jakub (referee) ; Baláš, Marek (advisor)
The main aim of this bachelor thesis is a proposal of a heat source for a specific house. The first part is a research of different heating technology. In the second part there is a shortlisting of heat sources for this specific house and then calculating of costs for the selected heating sources. These costs are calculated from heat losses of the object. After the economic comparison one source is selected, from which costs of heating are calculated with three versions of possible insulation of this house.
Design of heating and ventilation detached house
Kocourek, Tomáš ; Elbl, Patrik (referee) ; Baláš, Marek (advisor)
The bachelor's thesis deals with the choice of the ideal method of heating and ventilation for a specific detached house. The first part of the thesis provides an overview of available technologies. The following part deals with the description of the properties of a detached house, on the basis of which the most suitable heat sources and methods of ventilation are selected. In the final part of the thesis, these technologies are compared both in terms of initial and operating costs, as well as payback period of the investment.
Gasification Technologies in the Czech Republic and Abroad
Kunert, Šimon ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This bachelor's thesis deals with gasification technologies in the Czech Republic and abroad. The first part describes brief history of gasification, characteristics of the process, the most important types of equipment intended for this purpose, what are their properties and possibilities of use in practise. A separate part is dedicated to biomass gasification. The second part is dedicated to companies and institution that have dealt with this technology. There is a place of business in which the company operates, and a brief description of their equipment with specific use in practice.
Heat recovery
Kovaříček, Jakub ; Toman, Filip (referee) ; Baláš, Marek (advisor)
This work deals with the design of a heat exchanger for the use of the heat of the gas generated during the gasification of biomass. The gas flowing in the tubular space of the exchanger will be cooled to the required temperature by the air flowing in the intermediate tube space. It is therefore a gas-air bundle exchanger, the outlet air temperature of which is unknown. The introductory part includes an overview of possible designs of exchangers according to several parameters, requirements for exchangers and their functions. The second part deals with the design of the exchanger itself, starting with the determination of physical and other properties of working media, through geometric parameters, the balance of the exchanger and finally the determination of pressure losses of the exchanger.
Emissions from the burning of garden waste
Kuznetsova, Oksana ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the issue of production of gaseous and solid pollutants in the incineration of garden waste. The aim was to carry out and evaluate the experiment. During the evaluation, it was found that the incineration of garden waste produces many times more emissions, than the incineration of wood in the boiler. The reason for the high emission concentrations was the fuel composition and the combustion process. Furthermore, fine particles in the range 17.5–532.8 nm were investigated. In the theoretical part, a literary search was created, which was based on Czech and foreign professional literature.
Emissions from biomass combustion
Vaněk, Michal ; Lisá, Hana (referee) ; Baláš, Marek (advisor)
The thesis deals with harmful substances originating as products of biomass combus-tion and possibilities of reducing their emissions from boilers for household heating. First of all, biomass is introduced and a description of important fuel properties in terms of its combustion is given. Secondly, the characteristic of the combustion process and origination mechanisms of individual substances are presented. This is followed by a description of the properties of these substances and their impacts on human health and the environment. The purpose of the next chapter is to present the reader with current legislation addressing the emissions of small boilers. Then a separate chapter describes possible methods that can be used to reduce emissions of these devices. Finally, several measures in the form of modifications and devices, capable of reducing harmful emissions of small boilers are given.
Methods of CO2 separation from air, ways of its use and long-term storage
Kober, Ondřej ; Baláš, Marek (referee) ; Škorpík, Jiří (advisor)
Combustion of fossil fuels creates greenhouse gas emissions that cause global warming. The most important of these gases is carbon dioxide. Although it occurs naturally in the atmosphere, human emissions upset the balance of various natural processes. The aim of this bachelor’s thesis is to conduct a background research in the field of carbon dioxide capture, storage and utilization. The thesis also describes the role of carbon dioxide in the atmosphere, its cycle and human influence on carbon dioxide concentration.
Design of a source for heating a family house
Bartlíková, Zuzana ; Elbl, Patrik (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with heating sources for family houses. Their advantages and disadvantages and issues with heat sources selection. The first part of the thesis contains basic information about methods of heating. The second part is already practical, where are used knowledge with heat source design for specific family house. In the end of the thesis are heat source designs evaluated, compared and a heat source is selected. This heat source would be possible to buy, if is there some possible change for current existing heating source in future.
