Project ORC -cycle
Černý, Jakub ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
The aim of this thesis is the project for biomass cogeneration units using ORC cycle and subsequent use of thermal energy for drying wood biomass for a briquetting line. The introducing sections describe the principle of cogeneration, organic Rankine cycle (primarily the indication of potential applications and their use in practice) and the selection of the proper working fluid. The following sections provide a technical description of the selected plants for cogeneration unit, total circulation scheme and calculation of the evaporator working fluid. The last section is devoted to the economic evaluation of three variants according to the investor's task to design a better option for implementation.

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.
