WIPO Patent Application WO/2018/051245
Kind Code:
A3
Abstract:
The present invention provides a turbine shaft bearing apparatus comprising inlet side and outlet side bearings for providing support to a turbine shaft to which are connected a plurality of turbine wheels such that the turbine shaft, the two spaced bearings, and the plurality of turbine wheels are coaxial. The outlet side bearing is protected from overheating by the motive fluid by a solid bearing housing which includes a conduit through which a lubricating medium for lubricating said outlet side bearing is supplied. The present invention is also directed to a turbine module comprising a plurality of axially spaced turbine wheels, a structured bleeding exit opening formed in an outer turbine casing; and a passage defined between two of the turbine wheels and in fluid communication with the bleeding exit opening, wherein expanded motive fluid vapor is extracted through said structured bleeding exit opening for heating the motive fluid condensate.
