Optimization Models in Energy Production
Němcová, Lucie ; Bednář, Josef (referee) ; Popela, Pavel (advisor)
This bachelor's thesis focuses on optimization of a boiler's size of a waste incineration plant from an economic point of view. The problem was approximated by discretization because random parameters with normal distribution occured in the incineration plant model. To evaluate the quality of such approximation there were created confidence intervals using random sample information, independent random number streams method and common random number streams method. Used methods were compared and the smallest number of scenarios that aproximates the problem "well enough" was proposed in the last part of this thesis.

Waste incineration in states adjacent to Czech republic and the potential of international waste market
Kadleček, Vít ; Frýba, Lukáš (referee) ; Ferdan, Tomáš (advisor)
This bachelor thesis deals with mapping of current and planned waste incineration plants in states bordering with the Czech Republic, and with the potential of international waste market. The introduction of the thesis describes the history and function of the waste incineration plants. The first main part, the legislation, defines waste incineration as energetic usage of waste, placing waste incineration to waste management and legislative conditions for realization of transportation across borders. The second main part informs about current and planned foreign waste incineration plants, which are located near to borders of the Czech Republic, because of formation of competition for planned projects in the Czech Republic.

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.
