Turbine shaft bearing and turbine apparatus

The present invention provides a turbine shaft bearing apparatus, comprising two axially spaced, 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 all coaxial, wherein the outlet side bearing is protected from overheating by motive fluid expanded by one or more of the plurality of turbine wheels or stages by a solid bearing housing which surrounds the outlet side bearing which is supported and provided with a conduit through which a lubricating medium for lubricating said outlet side bearing is supplied from a port external to said turbine. The present invention is also directed to a single turbine module, comprising a plurality of axially spaced turbine wheels, each of which constitutes one expansion stage of said turbine module, being connected to a common turbine shaft and coaxial therewith; an inlet through which motive fluid vapor is introduced to a first stage of said 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 is extracted through said structured bleeding exit opening and is supplied to a heat exchange component, for heating the motive fluid condensate.. ...

Device and method for minimizing the effect of ambient conditions on the operation of a heat exchanger

A heat exchanger system for cooling liquid having a plurality of finned tube arrays and a plurality of fans for inducing air through the finned tube array comprising: at least one wind deflector installed along the long side of the finned tube arrays on at least one side of the arrays. The present invention for includes a method for minimizing the undesired effect of wind on the operation of a heat exchanger system for cooling liquid having a plurality of finned tube arrays and a plurality of fans for inducing air through the finned tube array, the method comprising the steps of: setting the angle of deflection of the wind deflectors other than the angle of deflection of the uppermost position of the wind deflectors; collecting readings of outlet temperature sensor of the heat exchanger, ambient temperature, wind sensor and inlet air pressure sensor of the heat exchanger; recording readings of outlet temperature sensor of the heat exchanger, ambient temperature, wind sensor and inlet air pressure sensor of the heat exchanger; comparing readings of outlet temperature sensor of the heat exchanger, ambient temperature, wind sensor and inlet air pressure sensor of the heat exchanger to previous readings; and carrying out a correction command if the readings have changed.. ...

Geothermal power plant

The present invention provides a power plant whose motive fluid is geothermal fluid, comprising: a high-pressure steam turbine to which geothermal fluid is supplied to produce power; a high-pressure condenser to which the geothermal fluid exhausted from the high-pressure turbine after being expanded therein is supplied and condensed, said high-pressure condenser being configured with a port through which non-condensable gases contained in the geothermal fluid supplied to the high-pressure turbine are extractable in an extraction process and further configured to use heat being released during condensation of the high-pressure steam turbine exhaust to vaporize the steam condensate produced therein for producing low pressure steam without non-condensable gases; and a low-pressure steam turbine for producing power from said low-pressure steam without non-condensable gases supplied from said high-pressure condenser.. . ...
