Performance Test of Double-stage Rankine Cycle Experimental Plant for OTEC

Abstract

Ocean thermal energy conversion has gained focus generating stable electric power while providing additional benefit. By some research, it is shown that using a double-stage Rankine cycle is theoretically more efficient than a single-stage Rankine cycle. Moreover, several studies have been made on the experimental study of a double-stage Rankine cycle. But the comparison of theoretical result with experimental result has never been studied so far. In this research, it was demonstrated a double-stage Rankine cycle experimental plant, and attempted to compare experimental result with theoretical result.
