摘要： A cascade organic Rankine cycle plant comprising a hot source, at least a first high temperature organic Rankine cycle and a second low temperature organic Rankine cycle, said cycles comprising at least one preheater, at least one vaporizer, at least one turbine, at least one condenser, wherein the hot source first supplies a vaporizer of the high temperature cycle, then the vaporizer of the low temperature cycle and finally it is divided into two flows which supply a first preheater of the high temperature cycle and a preheater of the low temperature cycle. The first high-temperature organic Rankine cycle comprises a further vaporizer operating at an intermediate pressure between the vaporizer pressure of the high temperature cycle and the vaporizer pressure of the low temperature cycle.

摘要： An organic Rankine cycle system with cascade cycles provided with a first organic Rankine cycle which operates at high temperature, in which a first organic working fluid carries out a heat exchange with a hot source fluid and a second organic Rankine cycle which operates at a temperature lower than the temperature of the first organic Rankine cycle and in which a second organic working fluid carries out a heat exchange with the same hot source. The evaporator of the first organic Rankine cycle is fed by the entire flow rate of the hot source fluid, while the evaporator and the preheater of the second organic Rankine cycle are fed by a first partial flow of the hot source fluid, the remaining second partial flow of the hot source fluid being used to partially carry out the preheating of the organic working fluid of the first organic Rankine cycle.
