Application of stochastic programming methods for the purpose of energy producing system
Šomplák, Radovan ; Mrázková, Eva (referee) ; Popela, Pavel (advisor)
This thesis deals with the evaluation of the strategic investment in the waste-to-energy plant development. The central supply of heat and the incineration plant connection can be provided for example by the distribution network. The objective is to find financially feasible solution regarding uncertain development of waste management and energy market. A heat supplies to district heating network significantly influences the strategic decision. A two-stage stochastic programming based on the scenarios and the GAMS software were applied to solve this task. The main contribution of this thesis is decision on crucial parameters of the waste-to-energy plant.

Entrance zone objects of WANEMI, a.s. paper-mill in Zábřeh
Horký, Jan ; Zemánek, Václav (referee) ; Zemánková, Helena (advisor)
The diploma thesis deals with the entrance zone objects nearby a to-be-built energetic-paper mill factory WANEMI, Inc. in Zábřeh. It consists of two objects: a presentation pavilion and an administrative building. My design combines a function of parking and administration into one single object to occupy less land. Garages are intersected by a big open skylight in the middle with some trees planted in - this way people are moving as if in the treetops. The exhibition pavilion is situated in the intersection of main view axes to landscape dominants. Their extension is projected even into the interior where they determine main spaces. Visitor of the building climbs the way up along the important views to finish his way upstairs in the main hall.

Potential of thermal utilization of waste in the Czech Republic
Studený, Vojtěch ; Baláš, Marek (referee) ; Kracík, Petr (advisor)
Bachelor thesis is discussing the potential of energy use of waste in the Czech republic. First part is describing the current ways of dealing with the waste. The thesis includes description of each procedure and its positive and negative aspects. The next part is dedicated to methods of technical use. Then there are described the basics of heating industry and effect thermal use on the environment. The last part is dealing with theoretical idea of energetic complex for energetic use of waste. The idea itself is based on calculations of the potential of energy in the waste.

Effectiveness Evaluation of Waste-to-energy process
Klimek, Petr ; Martinec, Jiří (referee) ; Pavlas, Martin (advisor)
This diploma thesis is focused on the evaluation of the effectiveness of using municipal waste to produce energy. On the basis of legislation applicable in the EU methodology is summarized evaluation of the facility as an energy recovery of waste. In the thesis is also created a consecution to determine decisive coefficients of legislatively-based criteria. The consecution is applied to the case study. Thesis serves as the basis for a software application.

Low-potential heat utilization for electricity generation
Švábenský, Pavel ; Frýba, Lukáš (referee) ; Pavlas, Martin (advisor)
This work is concentrating on production of elektricity from waste heat. The work mainly deals with Organic Rankine cycle (further referred to as ORC), basic theory of ORC is summarised here and for comparison is given Rankin-Clausius cycle as well. Further part of the work is dedicated to ORC unit as a system, an overview of manufacturers of ORC units and their range of products is given here as well, short comparison of ORC units was carried out. Further the work is dealing with problems of the incinerator and the possibility of using the ORC unit. The conclusion of the work is dedicated to the ekonomic evaluation of the application of ORC in the Czech Republic considering the implementation study.

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.

Waste utilization
Čech, Roman ; Suzová, Jana (referee) ; Macháček, Jan (advisor)
In this task we will talk over the problems in this current society from the aspect of waste production and treatment in European Union. We will classify the waste distribution to the categories, we will focus for the legislatives and the standards of waste management. Also we will preview the production statistics and waste logistic in the Czech Republic and EU. We will focus even for the waste processing like a material for the energy production and development of waste economy hypothesis.

Stochastic optimization in AIMMS
Kůdela, Jakub ; Mrázková, Eva (referee) ; Popela, Pavel (advisor)
Tato diplomová práce uvádí základní poznatky matematického a především stochastického programování. Navíc se zabývá použitím softwaru AIMMS při vytváření a řešení optimalizačních problémů. Naším hlavním cílem je naprogramovat v softwaru AIMMS několik metod řešení problémů stochastického programování a ukázat jejich použití a užitečnost na vybraných problémech. Jedním z problémů, který jsme si zvolili, je model spalovny. Všechny AIMMS programy, které v našem textu použijeme a popíšeme, a jejich zdrojové kódy budou přiloženy v dodatcích.
