PURPOSE:To miniaturize an installation without use of a pressurizing pump by separating a two-phase flow into steam and hot water by means of a rotary separation type two-phase flow turbine and supplying the separated hot water to a direct heat exchanger in a binary generation set by making use of terrestrial heat. CONSTITUTION:A terrestrial heat two-phase flow H is supplied to a two-phase flow turbine 21 by piping 20, and separated into steam S and hot water W by driving said turbine. Then, steam S is supplied from piping 24 to an indirect heat exchanger 22 to heat a heat exchanging element 26. On the contrary, the hot water W is supplied to a direct heat exchanger 23 by means of piping 25 to permit said direct heat exchanger to exchange heat with a low boiling point medium L to heat this, allowing a steam L' of the low boiling point medium L to be yielded. In the direct heat exchanger 22, the low boiling point medium L passing through a heat exchanging element 27 is heated with the steam S to produce the steam L'. Thus, after this steam L' joins the steam L' via the direct heat exchanger 23, they are supplied to a turbine 29 to drive this, allowing a dynamo 30 to produce electric power. |
