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.

Steam Turbine for fossil power plant
Třináctý, Jiří ; Fichtl, Richard (referee) ; Fiedler, Jan (advisor)
This thesis deals with design is condensing steam turbines burning fossil fuels with nominal capacity of the generator of 250 MW with steam reheating and regenerative eight uncontrolled extraction points. The turbine consists of two bodies: a combined high-intermediate pressure section and low pressure parts with dual way outlet down into the water-cooled condenser. Work includes calculating thermal scheme for 100% and 75% capacity, specific heat consumption calculation and design of the flow HP-MP body. Further strength control and basic engineering design of high-medium- work completed by longitudinal section. Achievements are at the end of work compared with work 3a and the conclusion summarizes the advantages and disadvantages of the concept.
