Daily launches steam turbines and their impact on the life of the turbine
Štěpánová, Lenka ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
This thesis concentrates on the problem of steam turbines, which require daily cycling by reason of an unstable nature of the energy source. The first part focuses on the current trends which have caused still increasing demand for steam turbines designed for every day start-ups. There is a description of the steam turbine start-up procedure and the heat transfer theory thanks to which the list of the critical parts of the steam turbine has been selected and with respect to these critical points has been created the draft of technical measures for the turbine. The thesis is finished with an evaluation of the life of the steam turbine casing as one of the critical parts and with a proposal for a calculation of a start-up time of the steam turbine.
