Abstract
The invention concerns an ORC plant (Organic Rankine Cycle) for a conversion of thermal energy into electric energy, that comprises a heat exchange group for the exchange of heat between the thermal carrier fluid and a working fluid destined to feed at least one expander connected to an electric generator. The heat exchanger group comprises in succession at least one primary heater and a primary evaporator respectively for preheating and evaporation of the working fluid. According to the invention, on the side of the heat Exchange group, downstream of the primary heater, are present at least an auxiliary evaporator to evaporate a part of the working fluid by means of a heat exchanger with the fluid source coming from the output of said primary evaporator, a device for diverting said part of the working fluid flow from the outlet of said primary preheater towards the auxiliary evaporator, and a compressor designed to receive the working fluid from the auxiliary evaporator and to increase the pressure up to a level corresponding to a preset pressure level for the induction of the work fluid into the expander.
