Optimation and Innovation of Family Houses Heating
Dubnický, Ladislav ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The aim of this bachelor thesis is to make a summary of knowledge of today´s modern heating systems for family houses. Each types of systems are compared to each other from economic, operating and ecologic point of view. At the end of the thesis there is a model conversion of energetic costs for specific family house and projection of new heating system.

Gas Supply and Underground Gas Storages in Slovakia
Galbavý, Mário ; Poláčik, Ján (referee) ; Lisý, Martin (advisor)
The aim of this bachelor thesis is to describe the situation regarding the storage and supply of natural gas in Slovakia. Thesis is divided into 4 chapters. The first chapter deals with natural gas from a general point of view, from its properties to its possible use. The second part describes the situation of supplying Slovakia with natural gas. The third part deals with the ways of storing natural gas and individual underground reservoirs located in Slovakia. The final part describes the reasons for the storage of natural gas and the possibility of measures that can ensure the security of its supply.

GateCycle simulator and its applications
Svoboda, Adam ; Ťok,, Pavel (referee) ; Jegla, Zdeněk (advisor)
Hlavná náplň tejto práce je oboznámenie so softvérom GateCycle od spoločnosti General Electric a jeho následná aplikácia na simulovanie industriálneho parného kotla produkujúceho 120 t pary za hodinu. Dizajn práce je vo forme výučbového materiálu, ktorý môže byť použitý vo výuke predmetu procesného inžinierstva zameraného na simulačné softvéry. Prvá časť práce je venovaná krátkej teórii o simulačných softvéroch a uvádza niekoľko najznámejších procesných inžinierskych simulačných programov. Druhá časť je napísaná formou GateCycle manuálu. V krátkosti predstavuje pracovné prostredie a rozhranie softvéru, demonštruje ako vytvoriť a spustiť simulačný model, zadať vstupné dáta a vytvoriť reporty. Tretia časť práce je praktická, vybraný industriálny parný kotol je prezentovaný a následne je vybudovaný jeho simulačný model. Táto časť je vytvorená vo forme príručky „krok za krokom“ vysvetľujúcej ako vytvoriť model kotla a aké dáta boli zadané do jednotlivých procesných aparátov. Kotol je simulovaný v 3 režimoch, využívajúc zemný plyn, ťažký vykurovací olej, či dechtovú vykurovaciu zmes ako palivo a je prevádzkovaný za mierne rozličných procesných podmienok. V závere sú vypočítané spotreby paliva porovnané s reálnymi prevádzkovými dátami a je vyhodnotená presnosť výpočtov softvéru GateCycle v týchto konkrétnych prípadoch.

Design of station for natural gas flow measurement in transport network
Šrámková, Veronika ; Hudec, Martin (referee) ; Habán, Vladimír (advisor)
The main aim of the thesis is to design a metering station providing natural gas flow measurement. The beginning of the thesis is devoted to the theoretical introduction to the issue, especially natural gas, transmission network and metering stations. The second half of the thesis deals with the design of metering station itself, which is divided into three parts. The first part deals with the design of the number and diameter of the metering lines from both a technical and an economic point of view. In the next part, meters are selected, based on which the uncertainty of the proposed metering station is determined. The last part of the work deals with the design of a suitable shape of the measuring lines with respect to the natural gas flow, which is analysed by CFD simulation.

Problems of Russian-Chinese cooperation in energy sphere 2000-2010. The issue of oil and natural gas
Imrich, Jakub ; Pečenka, Marek (advisor) ; Litera, Bohuslav (referee)
Thesis Problems of Russian-Chinese cooperation in energy sphere 2000-2010: The issue of oil and natural gas is a work which is discussing main problems of cooperation between biggest producer and biggest consumer of energy in the world. My aim is to analyze these problems and answer the question, why is the mutual energy relationship not developing as we could logically assume. One of the objectives will not be analyzing mutual political disputes between these two countries. Firs part of the work offers brief excursion into the relationship in the past which was not very friendly. Second chapter is about different meaning of energy for Russian Federation and People's Republic of China and contains facts about bilateral trade considering oil and natural gas. Third chapter is most comprehensive and is pivotal for thesis and it analyzes problems of cooperation. This part of work examines inner problems of Russia, inner problems if China and main external factors which affect the energetic convergence of these two countries as well. Conclusions from the analyzed problems are then summarized in the last chapter. In this part there are also given some future prospects how the oil and natural gas trade between Russia and China might evolve in the future. In conclusion part there are briefly summarized...
