Thermoelectric generator for flue-gas duct of boiler to convert low-temperature waste heat to electricity
Třináctý, Jiří ; Baláš, Marek (referee) ; Brázdil, Marian (advisor)
With the dwindling supply of fossil fuels is increasing interest in the most efficient use of primary energy sources. In many of today's devices leaving a considerable part of the fuel energy wasted in the form of waste heat. As a partial solution suitable to demonstrate the application of thermoelectric generator, or devices that convert heat energy directly into electrical energy. The trend in recent years shows the growing interest in this technology and the development of new thermoelectric materials. In addition to the use of waste heat thermoelectric generators can be found in a number of other applications, primarily as a source of electricity in conditions where required minimal maintenance, reliability, reliability and durability. Text is divided into three parts: a theoretical part, the part dealing with the design and implementation of the generator, and a final evaluation. The theoretical part includes a description of the basic thermoelectric phenomena, thermoelectric materials and their properties, a description of the main components of thermoelectric generators and applications in which the thermoelectric conversion uses. Part of the design and implementation deals with the design of thermoelectric generator for chimney flue and comparison of the proposal with real measured values.

Semiconducting ceramics for thermoelectric application
Jebavá, Alžběta ; Koplík, Jan (referee) ; Bartoníčková, Eva (advisor)
This diploma thesis focuses on the syhnthesis of multicomponent ceramic system based on Ca-(Mn,Co)-O. The thesis is devided in theoretical and experimental part. The theoretical part is describing ceramic materials for thermoelectric application, preparation and synthesis of these materials and their processing. The experimental part is dealing with synthesis of ceramic powder which is processed to the porous ceramics. The properties of prepared porous ceramics are observed.

Low power thermoelectric generator
Lokaj, Jakub ; Pospíšil, Jiří (referee) ; Brázdil, Marian (advisor)
The bachelor thesis deals with the description the physical nature of the conversion of thermal energy into electrical energy and construction of thermoelectric generator. The work is divided into a theoretical part, practical part includes the design and experimental measurement constructed device and final assessment of thesis. The theoretical part describes the thermoelectric phenomena, properties of materials used for the manufacture of thermocouple, construction and electrical parameters of thermoelectric modules and applications of thermoelectric generators including a description of parts of which help to complete overall device. The practical part includes the design and construction of low power thermoelectric generator and experimental measurement connected device with the calculation comparing the predicted performance. In conclusion, besides to assessment thesis also outlines suggestions for further improvements the device.
