摘要： The invention concerns a turbine for the expansion of gas and vapour, comprising a body or case, a fixed external sleeve member, overhanging frontally from a frontal wall of said case, and a turbine shaft (15) extending coaxially and rotating in said external sleeve member (18) with the interposition of a supporting unit (19). The external sleeve member has a head flange to axially hold said supporting unit; the turbine shaft ends with a joint to connect it to a device to be operated. The supporting unit (19) includes ball bearings to support the turbine shaft (15) in said external sleeve member (18), and between said external sleeve member (18) and a contiguous end of said turbine shaft (15) an aggregate (50) is provided to generate an adjustable axial force so as to compensate the axial thrust of the turbine shaft to limit the application of improper axial loads on the ball bearings.

摘要： The invention is directed to an ORC (Organic Rankine Cycle) system at least partially co-generative for the production of electric energy and the heating of a fluid. The system includes at least two regenerative exchangers positioned in series on the route of the work fluid between the exit of an electric expander-generator group and the entrance of a condenser of the ORC system, and a heat exchanger-user connected by means of an offtake line to at least one of said regenerative exchangers to receive from them a part of the capacity of work fluid and crossed by the user fluid to be heated by means of a thermal exchange with said capacity of work fluid. A part of the capacity of the work fluid on exiting from the user exchanger is returned to the same regenerative exchanger.

摘要： A control method of a centrifugal compressor (C) mechanically coupled to an expansion turbine (TorC), the centrifugal compressor (C) being provided with at least a control system (20) of the absorbed power. The control method of the rotation speed of the turbine-centrifugal compressor group performs the following steps: —acting on the centrifugal compressor control system (20) of the absorbed power by means of a first controller (PID-f), in order to keep constant the rotational speed of the compressor mechanically coupled to the expansion turbine; —ensuring that the centrifugal compressor (C) remains in a stable operating condition by means of an admission valve (Vi) of the expansion turbine (TorC).

摘要： 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.
