Work process and equipment - uses thermal energy from heat sources evaporating easily boiled medium in heat exchanger

摘要

The thermal energy is taken up by a heat exchanger (1) in a closed circuit (2) for evapn. of an easily boilable work medium (3) with pref. less than 60 cal/g between 120 and 150 deg.C. The vapour at a pressure below or above that atmospheric in the closed system rises in a rise pipe (4) against the force of gravity, and in a further heat exchanger (5) is condensed. The thus produced liq. then runs via a drop pipe (6) through a turbine with connected generator (7) or similar device for energy prodn. The potential energy from the height difference between the top heat exchangers is used for work prodn., and the work medium then enters the first heat exchanger (1) via a pressure regulator valve (8). USE - To employ thermal energy for generating electricity or other work forms.
