Aerodynamické chování patního řezu lopatky posledního stupně parní turbíny velikého výkonu při nenávrhových provozních režimech
Luxa, Martin ; Synáč, J. ; Šafařík, P. ; Šimurda, D.
The paper is concerned with results of high-speed aerodynamics research on blade cascade. The blade cascade represents root section of the last stage rotor blades of large output steam turbine. Basic aerodynamic charakteristics of the blade cascade are presented together with flow field photographs in range of transonic velocities. Results are analysed and discused.
Aerosol in the steam turbine?
Kolovratník, Michal ; Hrubý, Jan ; Ždímal, Vladimír
The small amount of admixtures in steam circuits of power stations influences their life-expectancy and energetic efficiency. It is likely that non-volatile admixtures are in the environment of the dry (superheated) steam transported in the form lf dry particles or concentrated nanometric droplets, aerosols. For the detection of these particles a new sampling line is proposed, using the aerosol technology. It will be possible to connect the sampling line to sampling ports of a steam turbine.
Vliv přechodu z nominálního režimu ke sníženému na změnu pole proudění v NT stupni 210 MW turbíny
Jonáš, Pavel ; Mazur, Oton ; Uruba, Václav
HW-CTA measuring method was applied at the investigation of wet steam flow downstream the LP stage of a 210 MW turbine. Time averaged characteristics of flow field and temperature field were determined as well as the phase averaged ones.
Výskyt velkých kapiček v okolí posledního stupně parní turbíny 210 MW
Uruba, Václav ; Jonáš, Pavel ; Mazur, Oton ; Řehák, Vratislav
The method of detection of big water droplets in the wet steam flow based on hot-wire anemometry is used for analysis of the flow behind the last stage of the 210 MW steam turbine in two operational regimes.
Předběžné výsledky o charakteristikách proudění mokré páry za NT stupněm 210 MW turbíny
Jonáš, Pavel ; Mazur, Oton ; Řehák, Vratislav ; Uruba, Václav
Results of the unsteady wet steam flow structure investigation are presented. Measurement was executed by means of a single rotary inclined hot-wire anemometer.
