Abstract
U ovome završnome radu analiziran je utjecaj srednjih temperatura dovođenja i odvođenja topline na toplinski stupanj djelovanja parnog postrojenja s pregrijavanjem pare. Opisane su osnove kružnih procesa općenito kao i kružnih procesa s vodenom parom. Zatim je objašnjen način proračunavanja dovedene topline, odvedene topline, rada te toplinskog stupnja djelovanja desnokretnog ClausiusRankineovog kružnog procesa. Navedeni proces prikazan je u ts i hs dijagramima za zadane podatke. Definirana je promjena srednje temperature dovođenja topline promjenom najveće temperature pregrijanja, tlaka u kotlu kao i uvođenjem međupregrijanja. Rezultati rada prikazani su tablično i grafički u usporednim dijagramima.
Abstract (english)
In this final paper, the influence of mean heat addition and rejection temperatures on the thermal efficiency of a steam power plant with steam superheating has been analyzed. The basics of cycles in general as well as cycles with water vapor have been described. Then, the method of calculating the added heat, the rejected heat, the work and the thermal efficiency of the clockwise Rankine cycle has been explained. The above process has been shown in ts and hs diagrams for the given data. The change of the mean heat addition temperature is defined by the change of the maximum superheating temperature, the pressure in the boiler as well as the introduction of the reheating. The results of the work are presented in tables and graphs in comparative diagrams.
