Increasing the energy efficiency of industrial heating plant
Spišák, Lukáš ; Lisý, Martin (referee) ; Kracík, Petr (advisor)
This bachelor thesis consists of two parts. The introductory chapters are devoted to the basic description of cogeneration and trigeneration technologies, focusing on the description of cogeneration units and cooling devices. The second part of the thesis compares two specific ways of using cogeneration units and gas boilers in the CHEMOSVIT ENERGOCHEM a.s. in the town Svit. Subsequently, both variants are evaluated energetically and economically.

Automated Control and Monitoring of Central Heating for Older Buildings
Mužila, Matej ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The purpose of this thesis is a design of an automated heating regulation system for an old building. The thesis consists of a system architecture design, an implementation of the system, including prototype manufacturing of the required devices, and testing of the whole system in practice, with focus on functionality and efficiency. Several hardware devices were designed and manufactured, for which appropriate controlling software was implemented. The implemented software architecture enables users to control the system using a graphical user interface, and allows for an easy extension of the system. The graphical user interface, which is accessible both locally through a touchscreen and remotely using a web application, enables users to easily configure connected devices and regulated zones, and to set temperature level in the defined zones variably depending on a week day and time. The user interface also provides statistics about the heating system. The implemented automated heating regulation system was successfully tested in real conditions of a flat in a historical building. The system can be extended both hardware-wise and software-wise.

Grate RDF Boiler
Krolák, Michal ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
This master's thesis deals with design of steam grade boiler for burning refuse derived fuel with power output of 70 t/h. The assignment contain a requiered steam output parameters and composition of fuel. From this composition of fuel is calculated stoichiometric calculation, the heat loss and the efficiency of boiler. After that follows a design of the boiler with closer design of each of the heating surfaces.

Proposal heat sources for home heating
Dobai, Szabolcs ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with heating and selection of appropriate heat sources for family houses. The first chapter describes heat sources used for heating by type of fuel. The second part is devoted to calculation of the energy balance and the amount of heat required for a particular object. According to the results, five possible options are selected. At the end, the economic evaluation of the selected heat sources are processed and the most suitable one is selected. The attachment provides floor plan, section, list of the elements (windows and front door) and also appearance of the house.

Efficiency of the energy use of biomass
Szelecky, Zsolt ; Brázdil, Marian (referee) ; Baláš, Marek (advisor)
This final thesis deals with the theme of energetic usage of biomass and its energy efficiency. In the first part the term „biomass“ is explained and classified into categories. The main part of this work deals with technology converts of raw biomass into valuable energy products. The final section is closely connected with the previous part, where the emphasis is placed on energetic effiency of abovementioned technology converts.

Heat Recovery Steam Boiler for Cogeneration Unit
Vilga, Filip ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
The main goal of this Master's thesis was to design heat recovery steam boiler for cogenera-tion unit of a biogas plant while flue gas was flowing from an engine exhaust. Its temperature and required pressure of a steam were assigned. The thesis contains thermal, aerodynamic, hyd-raulic calculations and verification of wall thicknesses for pressure parts of the boiler. Follow-up results of these calculations served for making of projection drawings as well as equipment needed for reliable boiler operation.

Optimation and Innovation of Family Houses Heating
Dubnický, Ladislav ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The aim of this bachelor thesis is to make a summary of knowledge of today´s modern heating systems for family houses. Each types of systems are compared to each other from economic, operating and ecologic point of view. At the end of the thesis there is a model conversion of energetic costs for specific family house and projection of new heating system.
