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： A binary geothermal system (100) comprising: - at least one organic Rankine cycle (10) having at least one supply pump (PUMP) for feeding an organic working fluid, in liquid phase, of at least one heat exchanger (EV1) for heating the organic working fluid until its transformation vapor phase and to its eventual overheating, an expansion turbine to expand the organic working fluid vapor, a condenser (CON) bringing in a liquid phase the organic working fluid, - a geothermal source (20) comprising a geothermal liquid and a geothermal vapor, wherein the organic working fluid is vaporized directly or indirectly through a flow (S1) of geothermal vapor in the heat exchanger (EV1) and is preheated by a flow of geothermal liquid (B1) in a first pre-heater (PRE1), and the organic working fluid is preheated also in a second pre-heater (PRE2) which exploits the thermal energy contained in a flow rate (S4) formed by the gas mixture and by the geothermal vapor fraction (S2) which is not condensed, and exit from the heat exchanger (EV1) or by a exchanger (DC).

摘要： A method for producing syngas from preferably vegetal biomass is described. The method provides for the use of a fixed bed gasifier, equipped with two reactors. The biomass is fed to both reactors together with a primary flow rate of air. Advantageously, the method according to the present invention is different from the known art since a secondary flow rate of air is withdrawn from the first reactor at the area where the biomass dries, and fed to the second reactor at the area where the biomass dries, and vice versa, alternately during time. Alternatively, an oscillating air flow is created in each reactor. The achievable result is a greater syngas production, but not exclusively. The syngas quality is improved too, since the biomass has a longer time for completing the gasification reactions.

摘要： A turbine of an organic Ranking cycle (ORC) is described. The turbine includes a shaft supported by at least two bearings and a plurality of axial stages of expansion, defined by arrays of stator blades alternated with arrays or rotor blades. The rotor blades are sustained by corresponding supporting disks. A main supporting disk is directly coupled to the shaft in an outer position with respect to the bearings, and the remaining supporting disks are constrained to the main supporting disk, and one to the other in succession, but not directly to the shaft. Some of the remaining supporting disks are constrained to the main supporting disk and cantileverly extend from the same side of the bearings that support the shaft, so that the center of gravity of the rotor part of the turbine is shifted more towards the bearings.

摘要： A turbine (1) of an Organic Rankine Cycle ORC, comprising a shaft (4) supported by bearings (8) and a plurality of mechanical seals (10, 11, 18, 21) arranged around the shaft for confining the operating fluid expanding in the turbine, is described. The seal are arranged so that to define and preserve the insulation of four chambers arranged in succession along and around the shaft. A first chamber (101) is among the turbine expansion stages and the second chamber (102), named buffer chamber; a fourth chamber (104) is the nearest to the bearings and the third chamber (103) is in-between the second and the fourth chamber. In the buffer chamber a barrier fluid (302) is fed and, advantageously, it is the same organic operating fluid fed to the turbine. In this way the confinement of the operating fluid in the turbine and the respective non-contamination are guaranteed. A corresponding method for confining the operating fluid in a turbine is also provided.
