Steam turbine - condensation formation and discharge
Zouhar, Adam ; Filip, Patrik (referee) ; Fiedler, Jan (advisor)
Master thesis is dealing with the issue of condensate creation and removal from the Nesher Ramle steam turbine during start-up and steady state. At the beginning a preliminary calculation of heat balance and the turbine itself is done. It is followed by description and design of drainage system supplemented by calculation of the steam flow through the orifices. Steam flow calculation was done via S. D. Morris, Pavelek with Kalčík and Ambrož, all three methods were compared. The main goal is the theoretical calculation of the amount of condensate created during start-up which is influenced by its initial state from which it is started. Three default states are considered, cold, warm and hot. In the last chapter the comparison of theoretical calculation with the measured data on real turbine is done and it is supported by the evaluation of the data from the measurement of the steam turbine at steady state on maximum power and half power. From the steady state analysis, percentage of water flow to expander from the total amount of condensate formed in the turbine were obtained.

Steam condensing turbine
Štěpánová, Lenka ; Krbek, Jaroslav (referee) ; Fiedler, Jan (advisor)
The aim of this Master’s thesis is to design a steam condensing turbine with three bleeds. First, a heat balance of the steam cycle is calculated, followed by thermodynamic and stress calculation of the turbine blading and design of a gland steam system and drain system. A price proposal is suggested for the given steam turbine. In the end, a design drawing of the steam turbine is constructed.

Evaluation of changes in the functionality of the drainage systems of arable soils at Vysočina based on image analysis of time series multispectral satellite images
ŠTEFL, Jan
In Czechoslovakia 1 078 000 ha of agricultural land were drained. At present, the drain systems located in these areas are at the end of their lifetime because of unsatisfactory maintenance of these systems. This project deals with evaluation of changes in functionality of the drain systems used in arable land in Vysočina. In examined territory of the region Vysočina (except the district Pelhřimov) there were accidentally chosen testing spaces where the drain systems fill 25 -75% of surface area and where the analysis of vegetative factors and humidity was done. As a source for the vegetative factors and humidity, there were used satellite photographs Landsat. The aim was to discover whether the vitality of vegetation and humidity in the part of land with the drain systems and without the drain systems differ.
