District heating systems in the Czech Republic in the context of legislative changes
Hylas, Martin ; Poul, David (referee) ; Putna, Ondřej (advisor)
The bachelor thesis focuses on the analysis of the issue of district heating (DH) with regard to legislative changes in the European Union. The first part deals with the analysis of the issue and the evaluation of the state of CZT in the Czech Republic. The European Union's position on climate change, caused by increasing greenhouse gas emissions, which are significantly produced by DH sources, is also discussed. The research part ends with an analysis of possible changes in the heating industry leading to the fulfillment of legislative requirements in the future. The second part of the bachelor's thesis deals with the elaboration of a case study of the change of the fuel mix for the heat source in the existing locality with the use of the technical-economic model. The main goal is to evaluate the usability of renewable resources (biomass, waste) as primary fuels instead of natural gas. The result of the practical part is a comparison of individual variants and changes in the cost of producing 1 GJ of heat compared to the reference variant.

Energy use of waste
Hrubý, Radomír ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
The content of this work is an evaluation of the Waste-to-Energy technology. The in-troduction describes current position of the Czech Republic on waste management. Including description of individual waste management technologies. The following chapter deals with the use of waste as a fuel for energy purposes. The principle of waste incineration and pyrolysis technology is elaborated here. Further, are discussed the methods of purification of individual components of flue gas. The penultimate chapter is devoted to legislation that affects the ecology of Waste-to-Energy technology and the comparison of emissions of various stationary sources of pollution which are producing energy. In conclusion, there are described facilities for the energy utilization of municipal waste in the Czech Republic, which are supplemented by two facilities from neighboring states.
