STEAM POWER CYCLE SYSTEM

WIPO Patent Application WO/2007/000811

A1

[PROBLEMS] To provide a steam power cycle system in which thermal energy based on the temperature difference between a high temperature heat source and a low temperature heat source can be utilized effectively and sufficient efficiency can be secured by rationalizing the constitution and arrangement of each apparatus, e.g. a heat exchanger, in a cycle, and the system can be made more compact and inexpensive. [MEANS FOR SOLVING PROBLEMS] An evaporator (10) is provided with a heat exchanging section (12) allowing heat exchange between a high temperature heat source and working fluid, and the internal space (11f) of shell communicating only with the working fluid outlet of the heat exchanging section. Since the working fluid under multi-phase state in the internal space (11f) is separated into gas phase component and liquid phase component when the working fluid flows out into the internal space (11f) after subjected to heat exchange with the high temperature heat source at the heat exchanging section (12), gas phase working fluid and liquid phase working fluid can be taken out under separated state from the evaporator (10). Consequently, a gas/liquid separator is not required, the entire system can be made compact, piping associated with the gas/liquid separator can be omitted, and the amount of work being taken out effectively can be increased by reducing the loss.
