Power-generating plant having increased circulating force of working fluid

Patent ·
OSTI ID:6030293

A power generating plant which includes a direct contact-type heat exchanger. A low-boiling point medium such as freon and a heat-source medium such as heated oil, are injected from a lower portion of the heat exchanger so that the two media are brought into direct contact with each other thereby vaporizing the gaseous low-boiling point medium. The low-boiling medium acts as a working fluid while it circulates through a closed cycle of the plant which includes a turbine and a condenser. The heat-source medium, circulates in a closed cycle of the plant which includes a heating unit.
