|発明の名称||STEAM POWER CYCLE SYSTEM|
PROBLEM TO BE SOLVED: To provide a steam power cycle system for enhancing performance of the whole system, by maximally approaching the temperature of a working fluid of changing a phase to the temperature of a heat source, by properly advancing heat exchange between the working fluid being a non-azeotropic mixture and the heat source.
SOLUTION: A plurality of condensers 14 and 15 are arranged in a state of being connected in series, and a gaseous phase working fluid coming out of an expander is respectively introduced into the respective condensers 14 and 15, to be condensed, and thereby, the constituting ratio of the mixture in the working fluid is changed with every condensers 14 and 15, a rate of a low boiling point substance of the working fluid is enhanced toward the condenser 15 of a rear stage, the condensation temperature of the working fluid can be lowered more than the case of the front stage side condenser 14, the respective condenser outlet temperatures of the working fluid are successively lowered, the temperature of the working fluid is maximally approached to the low temperature fluid temperature, and cycle heat efficiency is surely improved by efficiently using a temperature difference in the heat source.
