Steam turbine - pipeline design
Kotas, Jakub ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The master thesis deals with the design, tracing and dimensioning of condensate pipeline. In the beginning, a preliminary calculation of heat balance is done. It is followed by a description of the main condensate system supplemented by the computational design of pipeline and the calculation of pressure losses in this pipeline. The crucial part of the thesis is the calculation of pressure losses, which is done in two ways. The first approach to calculation of pressure losses in the pipeline is calculated using values of representative resistance coefficient for pipe ele-ments using Idelchik literature and for individual types of valves using values from datasheets of Siemens Energy suppliers. In the second approach to calculation representative resistance coefficients for pipe elements and individual types of valves CRANE literature are used. Then both approaches of choosing representative resistance coefficients are compared and evaluated. Based on the calculated values, a suitable pump is selected at the end of the master thesis.

Condensation heat exchanger beyond CHP unit
Sojka, Jiří ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this thesis is to design the condensation heat exchanger for stationary engine running on natural gas. Flue gas condenser is designed for universal use of refrigerants (i.e. water or 35% fusion ethylene-glycol in water) and their working temperatures. The work includes theoretical, computational and design part. In the attachment is located the drawing documentation to flue gas condenser.

Design of heating water heat exchanger, capacity 200 MW
Vašíček, Jakub ; Kól, Přemysl (referee) ; Baláš, Marek (advisor)
The thesis is focused on the design proposal of thermal heaters for heating water in heat-exchanger station with a total output of 200 MW. The aim of the work is conceptual design of heat exchangers, thermal and hydraulic design of individual heaters and preview of flow of mass and energy. The outputs of the work are written calculations, design drawing of one heater and design of a heater arrangement in exchanger station. The objectives of the work are filled completely. The work is focused on issues directly related to the actual design of heat exchangers, does not give a general overview of the topic. Thermal calculation is limited to the calculation of heat transfer surfaces for condensation of steam and condensate hypothermia.

Heat and stress analysis exchanger
Jedlička, Rostislav ; Šen, Hugo (referee) ; Baláš, Marek (advisor)
The main goal of master’s thesis is a propsal of the heat exchanger. The heat exchanger is double way of water side with the integrated air-vapor mixture cooler. Another aims are heat computation, heat loss computation, solidity dimensioning and selection of a material for a major selection. The last task is about detection of a vapor pressure trought the tube bundle.
