Power production in cogeneration units
Šaroun, Josef ; Vašek,, Vladimír (referee) ; Caha, Tomáš (advisor)
The aim of this thesis is the technical-economic evaluation of the advantages of combined pruduction of electrical and thermal energy, depending on the current offer price of feed, bonuses and allowances.. There are described co-generational technologies and used for units with performance up to 500 kWe. There are discussed in detail cogeneration units based on reciprocating internal combustion engines. The thesis contents evaluation of various modes of operation of co-generation unit, depanding on the results is chosen the most suitable mode. Daily yield was calculated in relation with prices paid for commodities and service. Co-generational contribution were considered as well as contribution for decentralized production of electricity. From the operational and economical point of view the most effective mode of running the co-generation unit is 12 hours mode. The economical evaluation of input was made. If the operational mode of the unit would follow the suggested mode, the financial return of input would be in two years. With the correct operation the co-generation unit would generate the income about 21,8 mil. CZK.

Trigeneration
Hadraba, Jiří ; Chroboczek, Libor (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is the recherche dealing with cogeneration and trigeneration consecutively. There are described prevailing primary units designated to the transformation of the energy of the fuel in cogeneration units to electricity and heat. The next chapters are dedicated to the absorbing and compression machine cooling. There are also analysed the possibilities of the heat accumulation and the influence of trigeneration on the enviroment.

Heating Plant Mydlovary
Víšková, Jaroslava ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
The topic of this bachelor thesis is the Heating Plant Mydlovary. Especially optimization of its flow and chaining the power sources regards to the financial rationalization. The main focus is on flow of co-generation unit TEDOM Quanto D1200, which is product of Tedom s.r.o. Heating plant also consists of two warm water boilers Kotad 800 (thermal output 5,44 ) and Babcock Wanson BWN 150 with the maximum thermal output 8,0 . This heating plant is located in South Bohemia, close to town Zliv. Zliv is supplied by heat by the Heating Plant Mydlovary. Most of the houses in the city is connected in the district heating system. Whole heating plant is property of company E.ON Trend s.r.o.

Cogeneration power plant
Ptáček, Martin ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with heat and power supply of the family house, which uses natural gas.The first part reveals cogeneration technology in general, especially cogeneration unit based on gas-engine (internal combustion engine).In the second part, the thesis focuses on energy budget (power-balance sheet) issue. Finally, the third and fourth chapter, deal with particular calculation of usability of cogeneration unit in the small family house. Due to a small final financial difference and large investment costs, with such a low heat and power consumption, this technology is unsuitable for this type of usage.

Biomass in heating systems of cities and villages - II
Tomšů, Ondřej ; Pavlas, Martin (referee) ; Máša, Vítězslav (advisor)
The work deals with district heating systems in towns and villages. It presents the heating supply system, features the history of district heating in the Czech Republic, divided into several characteristic periods and future outlook. The next chapter deals with the division and a description of heat sources. There are statistics shown in the use of district heating systems in the Czech Republic and European countries. A large part of the work is devoted to fuels used in heat sources and their distribution. The main emphasis is put on biomass, there are described all the important parameters, and its species, methods of processing and utilization for getting the heat. The work is concerned with cogeneration technology, which uses the joint production of heat and electricity, there are listed its main advantages and described trigeneration technology. The final part is devoted to the financial aspect of district heating systems. There are listed examples of effective projects, given the example of heat station with a very short period of return of investment and a final assessment of the economic and technological performance of new and existing district heating systems.
