PURPOSE:To permit both the intermediate liquid medium used for recovering the exhaust heat from a heat source and the working gas medium used for driving a turbine to make natural circulation by means of the difference of density between the liquid and gas, by carrying out heat-exchange between both mediums, through a direct contact heat exchanger. CONSTITUTION:The intermediate liquid heat medium 2 which recovers the heat through a heat recovering apparatus 1 and the liquid working medium 3 which is liquefied in a condenser 5 are introduced under pressure by the gravity, into the lower part of a direct contact heat exchanger 8. Both mediums are formed into two-phase stream consisting of gas and liquid through the evaporation of the working medium 3 and introduced into a gas-liquid distributor 10, and the intermediate liquid medium 2 is returned into the heat recovering apparatus 1 by the action of gravitation. After driving a turbine 4, the gas working medium 3 is liquefied in a condenser 5 and returned into a heat exchanger 8 by the gravity. |
