Optimizing injections from the condensate pump
Kordiovský, Jan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with the topic of the optimization calculation of the mass flow of injection from the condensing pumps of the second degree to the condensate of heating steam, flowing from the system of separation and reheating, with the main goal to achieve the maximum power of the block of the power plant. There is calculation of the secondary circuit of the nuclear power plant in Dukovany before and after the optimization. In the next part, there is calculated growth of electric power of the block, results are drawn in diagrams and technical solution is designed.

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.
