Abstract
A turbine shaft bearing apparatus in a turbine module includes two axially spaced turbine shaft bearings, including an outlet side bearing protected from overheating by a solid bearing housing which surrounds the outlet side bearing. The bearing housing being provided with a support including conduit for a lubricating medium. The turbine module has plurality of axially spaced turbine wheels connected to a common turbine shaft and coaxial therewith; an inlet through which motive fluid vapor is introduced to a first stage of the turbine wheels; a structured bleeding exit opening formed in an outer turbine casing of the turbine module; and a passage defined between two of the turbine wheels and in fluid communication with the bleeding exit opening, wherein expanded motive fluid vapor may be extracted through the structured bleeding exit opening and supplied to a heat exchange component for heating the motive fluid condensate.
