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.

Testing of high-temperature corrosion resistance of 16M03 steel
Šikl, František ; Kolomý, Štěpán (referee) ; Zemčík, Oskar (advisor)
The aim of this work is to design and perform an experiment that simulates the environment of a municipal waste incinerator. However, the whole process of corrosion in real life can take several years, so it is necessary to accelerate these processes in both higher areas and more aggressive environments. The investigated material is 16Mo3 steel. The first part of the work is a search of selected issues of corrosion and materials used in the energy industry. The next part of the work deals with the design of the experiment, which consists of several parts. These may include the appropriate choice of chemical compounds used or the choice of measured temperatures or sample preparation, the experiment being adapted to the available equipment of the BUT FSI workshop. In the last part of the work, testing of the specified material for temperatures of 900 °C, 975 °C and 1 050 °C is performed, while the composition of the mixture is designed as 35 wt. % Na2SO4, 30 wt. % KCl at 35 wt. % NaCl. The measured values are compared depending on the temperature, where, as predicted, a larger graphical dependence can be seen at higher values. At the end, the results of corrosion loss of 16Mo3 steel were compared with Inconel 625 superalloy, where the theory already differs from practice. Furthermore, chemical analyzes from the experiment were performed at 1 050 °C and, based on these obtained values, the proportion of individual elements can be adjusted with the salt mixture used. This adjustment is recommended to reduce the NaCl content due to the higher Na content, as well as to increase the KCl content due to the low K content.

Optimization Models for Waste-to-Energy Problems
Hošek, Jaromír ; Bednář, Josef (referee) ; Popela, Pavel (advisor)
The main aim of this thesis is to create a sequence of mathematical optimization models with different levels of complexity for the efficient management and waste energy utilization. Stochastic programming approach was utilized to deal with random demand and uncertain heating values. Hence, more applicable model of the waste-to-energy plant has been developed. As the next step, the model is enhanced by heating plant extension. Computations are realized for real-world data and optimal solution is found by using GAMS implementation.
