Estimating the term…
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.
A power generating plant comprising a first circulation means for circulating a low boiling point medium in a closed cycle, a second circulation means for circulating a heat source medium in a closed cycle, heat exchanger means operatively connected with the first and second circulation means for bringing the low-boiling point medium and the heat source medium into direct contact so as to generate a working fluid, the first circulation means includes first nozzle means arranged in a lower portion of the heat exchanger means for injecting the low-boiling point medium into the heat exchanger means, the second circulation means includes further nozzle means arranged in the heat exchanger means at a position lower than the first nozzle means for injecting the heat source medium into the heat exchanger means whereby said first nozzle means and said further nozzle means increase a force for circulating the working fluid.
