Abstract
U radu je izvršena analiza regenerativnog Rankineovog ciklusa s međupregrijanjem pare. Opisan je princip rada idealnog Rankineovog ciklusa, idealnog regenerativnog Rankineovog ciklusa i regenerativnog Rankineovog ciklusa sa međupregrijanjem, te su izvršene energijske analize navedenih procesa sa odgovarajućim shemama i dijagramima. Zadatkom je trebalo izračunati maseni protok pare kroz kotao, termički stupanj djelovanja ciklusa i ispitati utjecaj temperature međupregrijanja na termički stupanj djelovanja ciklusa u slučaju otvorenog zagrijača napojne vode, te u slučaju zatvorenog zagrijača napojne vode. Rezultati analize su pokazali da se uvođenjem regenerativnog zagrijavanja i međupregrijanja, u Rankineov ciklus, postiže povećanje termičkog stupnja djelovanja.

Parallel abstract (English)
This paper presents an analysis of the reheat-regenerative Rankine cycle. The paper describes the principle of the ideal Rankine cycle, the ideal regenerative Rankine cycle, and the reheat-regenerative Rankine cycle and energy analyses of the mentioned processes are performed with corresponding schemas and diagrams. In the assigned task it was necessary to calculate the mass flow rate of steam through the boiler, the thermal efficiency of the cycle and to investigate the influence of the reheated temperature on the thermal efficiency of the cycle, with open feedwater heater and with closed feedwater heater. The results of the analysis indicate that, by using the regeneration and reheat in the Rankine cycle, the thermal efficiency of the process increases.
