Parní turbína pro biomasovou elektrárnu
Urbánek, Roman ; Fiedler, Jan (oponent) ; Kracík, Petr (vedoucí práce)
Diplomová práce se zabývá návrhem kondenzační parní turbíny pro biomasovou elektrárnu s odběry pro topné ohříváky s teplotním spádem 60/80 °C v létě a 70/125 °C v zimě a odběry pro nízkotlakou regeneraci. Jmenovitý tepelný výkon výměníků je 0-10 MWt letních a 0-50 MWt zimních. V práci je proveden detailní návrh průtočných částí parní turbíny, od návrhu regulačního stupně, stupňovité části turbíny a pevnostní kontroly jednotlivých stupňů až po návrh vyrovnávacího pístu, systému ucpávek a návrhu ložisek. V závěru práce je vykreslena provozní charakteristika navržené parní turbíny.

Steam Turbine for the Waste to Energy
Gajdoš, Adam ; Fiedler, Jan (oponent) ; Kracík, Petr (vedoucí práce)
Diploma thesis deals with the design of the condensing steam turbine with power output 23.63 MW at 5000 rpm and an efficiency of 84.17% after optimization. The turbine contains one controlled steam extraction and four bleeds. The steam mass flow required by controlled steam extraction is 0-75 t/h of a total mass flow to the turbine 105 t/h. Design of the steam turbine is preceded by calculation of heat balance of the cycle. Then the thermodynamic and strength calculation of regulation stage and reaction staging flow channel are made. Thermodynamic calculation of the flow channel consists of preliminary and detailed calculation. It is detailed calculation that leads to the turbine parameters optimization. The design also includes gland sealing system and balance piston calculation. In addition to the strength calculation there is bearings load calculation included. In the end, the consumption diagram is made, showing the interval by which the turbine can be safely operated. Integrated part of the thesis is conceptual drawing of steam turbine section.
