STEAM PLANT PROCESSES WITH CONDENSATE PREHEATING

U završnom radu opisani su parni procesi koji omogućavaju pretvorbu toplinske energije u rad. Objašnjeni su kružni procesi, promjene stanja plina i procesi isparivanja i ukapljivanja. Obrađeni procesi su: Carnotov proces, Clausius-Rankineov proces, Clausius-Rankineov proces s pregrijavanjem pare i proces s predgrijavanjem kondenzata u mješalištu. Za svaki proces je napravljen proračun te je detaljno opisan. Na kraju je prikazana analiza rezultata, te usporedba procesa u odnosu na toplinski stupaj djelovanja, dovedenu toplinu i izvršeni rad.The final work describes steam plant processes which enable conversion from thermal energy to mechanical work. This work also describes cycle processes, gas state changes, evaporation as well as the condensation. The following processes are described: Carnot process, Clausius-Rankine process, Clausius-Rankine process with steam overheating and process with condensate preheating. For each process calculation is made along with detail description. Finally, data analysis of the results, is presented as well as comparison of processes in relation to the thermal efficiency, delivered heat and obtained work
