摘要： Organic Rankine cycle (300, 400, 500) comprising:
- an evaporator (1) where the pressurized fluid is heated, vaporized and brought into subcritical or supercritical conditions using the heat of a source;
- a turbine (2) where the fluid while expanding provides the useful work of the cycle;
- at least one pump (5, 5 ') where the liquid is brought from the pressure of at least one condenser (4, 4') to the evaporator pressure (1);
- a pre-heater (6), which using the same source supplies heat to the working fluid, bringing it to a temperature close to the vaporization temperature,
said organic Rankine cycle (300, 400, 500) further comprising
- a first recuperator (3) which receives a first portion of organic fluid vapor extracted from the turbine (2), and is connected to a first condenser (4), by means of a first circuit (10) at medium pressure;
- at least one second recuperator (3 ', 403', 404 ') which receives a second portion organic fluid vapor leaving the turbine (2) and is connected to a second condenser (4'), by means of a second low pressure circuit (11), said organic Rankine cycle (300, 400, 500) being characterized by at least one further pre-heater (301, 301') positioned in parallel with one or both of said first and second recuperator (3, 3').

摘要： Partially cogenerative organic Rankine cycle plant (100) comprising, along a main path (5) in which a main flow of organic working fluid flows:
- an evaporator (10),
- at least one turbine (20, 21, 22),
- a first condenser (40),
- a first supply pump (50),
- at least one preheater (60),
at least two heat exchangers enslaved to a heat user, said two heat exchangers being placed in series along a path (85) of the heat user and in which:
- a first heat exchanger is a further condenser (45) fed by a partial flow of organic working fluid, in the vapor phase extracted from an intermediate stage of the expansion phase, and
- a second heat exchanger (80) is fed by a partial flow of the primary heat source.
