Boiler-room apartment house
Lampa, Jan ; Vrána, Jakub (referee) ; Vališ, Ivan (advisor)
The introduction of the theoretical part of the thesis deals with condensing boilers. There is a description of the parts of boilers, gas combustion methods, the amount of combustion air and the overall running of condensing gas boilers. Other parts of the paper describe radiators, thermostatic valves, safety relief systems, piping and circulating pumps. The design section provides an illustrative example of the design of the heating system for a residential building with 12 apartments.

Heating of panel house with alternative preparation of TV
Bílek, Martin ; Adam, Pavel (referee) ; Horák, Petr (advisor)
The subject of this thesis is the heating and hot water preparation in the residential house in Brno. object has eight floors and basement. In each floor there are five residential units. In the basement there is a utility room with heating, gas boiler cascade. Used to heat-pipe heating system. Heating surfaces are plate and tubular body. The primary source of hot water is gas boiler. As a secondary source of alternative preparation with solar home stations. Each apartment has its own solar station.

Odsávání ve stolařském závodu
Lysáček, Pavel
The bachelor thesis is focused on dimensioning of the exhaustion system for joinery manufacturers and describes necessary adjustments for the smooth operation of the manufactory. The thesis also deals with the theoretical calculation for the output of the exhaus-tion system using the method of total pressure. For the calculation of an output needed for ensuring the smooth exhaustion of wood residues around machines the amount of exhausted air and the total pressure of the main branch of the exhaustion system are used.

Line constructions in selected EU countries: Study 5.300
Pulda, Jan ; Syllová, Jindřiška
Práce se zabývá procesem přípravy a povolování významných liniových staveb. Autoři dochází k závěru, že všechny uvedené státy upravují, ve srovnání s běžným stavebním řízením, zvláštním způsobem přípravu a povolování velkých liniových staveb. V žádném z analyzovaných států však neexistuje komplexní úprava určená společně pro všechny druhy liniových staveb.

Ukraine’s Position in Eurasian Transport of Oil and Natural Gas
Ruban, Andriy ; Vošta, Milan (advisor) ; Jeníček, Vladimír (referee) ; Wahla, Arnošt (referee) ; Terem, Peter (referee)
The thesis focuses on theoretical and empirical analysis of oil and natural gas flows in Eurasia and maps Ukraine's transit position in the regional oil and gas supply chain. The aim of the thesis is to objectively evaluate possibilities of Eurasian energy integration by enlargement of the European energy market further to the East and to prospect Ukraine's involvement into a new geopolitical energy alliance, driven by EU. This dissertation builds up on economical, geographical, historical and political premises of markets integration as well as system approach of energy alliances development. It argues that (i) energy integration on contrary to traditional economic stream can be explained by system approach and geopolitical stream of energy expansionism; (ii) EU infrustructural oil and gas projects imply deeper integration of EU member-states with involed non-members and (iii) Ukraine's oil and gas transit status within Eurasian region facilitates its growing involvement into EU energy intiatives guided by the European rules. The thesis is organized into three chapters. The first one is predominately theoretical and seeks to summarize current theoretical approaches towards integration and trends of energy markets in Eurasia. The second chapter introduces the role of oil and gas transport capacities and Ukraine's transit status in resolving disparities of Eurasian energy supply chain. The third chapter describes condition of Ukrainian oil and gas infrastructure and tackles issues for reformation of national oil and gas transit pipelines. Securing access to energy supplies has been a driving factor of global development since the industrial revolution. Increasing demand for oil and gas has undermined energy and economic security of world centers. In Eurasia Europe and Asia has been competing for fossil fuels originating from Russia, Middle East and Central Asia. Since recently Eurasian energy security problem is being solved by development of new supply routes. These infrastructural projects are initiated by oil and gas consumers, suppliers and transitors competing over control in the infrastructure. Such competition destabilises Eurasian relations, leads to energy "wars", political conflicts and increases supplies disruption risks. To secure stability of energy supply chain producers, transitors and consumers of oil and gas resources should integrate, closely cooperate and jointly invest into improving the existing supply routes and efficiency of fuels consumtion, production and transportation. Oil and gas should be traded for technologies and capital securing control in the infrustucture of mutual interests. Development of further bilateral and multilateral tools of joint interest would also help in resolving energy related contradictions of the participating parties. The leading role in driving energy integration in Eurasia belongs to the EU being the most mature and advanced integration grouping in Eurasia. EU realises TEN-e projects and from recently a common foreign energy policy aimed to strengthen external cooperation with oil and gas suppliers and transitors, including Ukraine. Since 1970s Ukraine has been an important oil and gas transitor for Russian and Central Asian oil and gas to Europe. Ukrainian pipelines intermediate 10 % of oil and 50 % of gas imports of Europe. To counterbalance Russian energy diplomacy over Ukraine, EU is supporting Ukraine's efforts in such energy alliances as INOGATE or GUAM. Ukraine's recent accession to the South Eastern-European Energy Community should improve stability of gas and oil supplies to Europe and facilitate reformation of national transit capacities.

Analysis of local defects of high-pressure pipelines
Micka, Michal ; Jíra, Josef
In their surroundings the local defects of pipelines influence stress and strain state in the pipe wall. They are significant concentrators of the stress and they have fundamental effect on load-carrying capacity and service life of the pipe. The field of the stress and strain in the surroundings of defects may be detected experimentally or it may be used numerical modelling by FEM. In this paper are presented results of the numerical modelling of the stress state in the pipe wall due to ovality of the pipe also in the surroundings of corrosion pits and further at the place of local inward denting (buckling) of the pipe wall.
