Definitions

  • ABSTRACT In a steam turbine installation, a condenser is disposed on both sides of a low-pressure turbine and the condenser along with the low pressure turbine are enclosed within a pressure-tight, cylindrical housing.
  • the housing supports both the low-pressure turbine and condenser on an external foundation.
  • the housing also includes a removable V-shaped segment extending along the entire longitudinal length, of the housing and disposed at an elevation above the turbine shaft. The V-shaped segment is of such width that the inside casings and rotors of the low-pressure turbine can be removed through the opening remaining after the V- shaped segment is removed.
  • a low-pressure turbine and a condenser are enclosed in a cylindrical pressure-tight housing which supports both the low-pressure turbine and the condenser.
  • the housing is supported on an external foundation.
  • a removable V-shaped segment is included on the housing at an elevation above the turbine shaft and which extends over the entire longitudinal length of the housing, such V-shaped segment being of such width that the removal of the inside housings or turbine casings and of the rotors of the low-pressure turbine can be effected through the opening which remains after the V-shaped segment is removed.
  • the cylindrical housing offers a compact and warp-resistant type of construction so that the housing can support the condenser as well as the low-pressure turbine.
  • the V-shaped segment opening on the upper part permits, on one hand, the easy removal of turbine parts while, on the other hand, providing for selfsealing at the separating line, or joint between the two parts upon re-installation of the V-shaped segment on the housing.
  • auxiliary elements and parts can be integrated into the housing. It is possible, for example, to dispose low-pressure preheaters below the lowpressure turbine inside the housing, the arrangement being such that the preheaters may be pulled out underneath the adjacent generator which is driven by the turbine. Furthermore, inlet lines for the auxiliary returns can be arranged to pass through one front face of the removable V-shaped segment. The inlets and outlets for the cooling water to the condenser may also be arranged to pass on one front face of the condenser.
  • the bearing between the two low-pressure turbines may be separated from the condenser chamber, by curved partitions or separating walls and connected with the upper side of the housing through an access passage so that inspection of the intermediate bearing is possible.
  • FIG. 1 is a schematic side view of a steam turbine installation having a high, medium and low pressure turbine and also showing the generator which is driven by the turbines.
  • FIG. 2 is a top view of the installation shown in FIG. 1.
  • FIG. 3 is a view taken along the line III-Ill in FIG. 1 and showing the front end face of the low pressure turbine and condensor housing.
  • FIG. 4 is a view showing the rear end face side of the turbine and low-pressure turbine housing as seen from the generator.
  • FIG. 5 is a longitudinal cross-sectional view through the housing taken along the line V-V in FIG. 3.
  • FIG. 6 is a transverse cross-section view through the housing taken along the line VI'VI in FIGS. 1 and 5.
  • FIGS. 1 to 4 show various outside views of a steam turbine installation. To facilitate the description and its comprehension, only very simplified illustrations have been selected and those parts that are not considered essential to an understanding of the present invention have not been included.
  • a steam power plant installation comprises a high pressure turbine l, a double-flow medium pressure turbine 2, and a low-pressure turbine disposed in a cylindrical housing 3.
  • the turbines drive a generator 4.
  • the cylindrical housing 3 encloses a condenser and also the low pressure turbine.
  • the housing 3 has on its upper side, a V-shaped segment 5 that extends over the entire longitudinal length of the housing 3 and which can be removed in an upward direction from the housing 3 so that the casings and rotors of the low-pressure turbine can be removed through the resulting opening.
  • the outlet lines-6 from the medium pressure turbine 2 pass into the front face 7 of the housing 3 and lead, inside the housing 3 to the individual low-pressure turbine stages.
  • the front side of the V-shaped segment 5 is provided with two connections 8 for the over-production or auxiliary return lines.
  • FIG. 4 is a view as seen from the direction of arrow A in FIG. 1, that is from the generator side, and shows low pressure preheaters 9 disposed below the lowpressure turbine. These low pressure preheaters 9 can be pulled out from beneath the generator 4, that is between the latter and its foundation supports 10.
  • FIG. 5 is a longitudinal section through the housing 3 showing two double-flow low pressure turbines 13.
  • the turbine shaft 14 for the turbines 13 is supported in hearings 15,16 and 17 with the front and rear bearing 15 and 17 being supported by foundation columns 18 and by the generator foundation 10 respectively.
  • center bearing 16 is mounted on the housing 3 through supported on a separate outside-lying foundation 22 by means of brackets or abutments 20 and hinged supports 21 as can best be seen in FIGS. 3 and 6.
  • the two condenser sections 23, that is the two sections which include the condenser tubes 24, are disposed parallel to the machine axis and on both sides of the low pressure turbine 13.
  • Each condenser section 23 is arranged in a segment which may subtend or occupy a quarter of the circumference of the condenser housing 3.
  • the steam pouring out from the exhaust pipes of the low pressure turbines 13 (one of the pipes 25 being shown in section in FIG. with the last row of turbine blades 26) can thus directly discharge into the condenser sections 23.
  • a condenser pressure will prevail in the interior of the entire housing 3 so that the housing itself must be designed appropriately pressure-tight which is particularly enhanced, however, by the cylindrical form of construction.
  • the housing for the low pressure turbines 13 can be supported on projections 34 on the condenser support walls.
  • low pressure preheaters 9 which are connected to the turbines 13 through suitable steam draw off lines 27.
  • the center bearing 16 for the low pressure turbine is separated from the internal condenser housing proper by means of curved sheets of metal 19 and can be reached or is accessible through an upwardly extending passageway or chute 28.
  • the contour 29 of the front face of the V-shaped removable segment 5 is illustrated by broken lines.
  • the segment 5 Installed into the segment 5 is also a curved sheet of metal 30 which has suitable openings not shown in the drawing.
  • the upper area enclosed by the metal sheet 30 can be used as a plenum chamber or over-production area so that the steam arriving via inlets 8 in the front-face side 7 can settle in this chamber and flow downward into the actual condenser chamber.
  • the condensate collects in a hot well 33 below the preheater 9 and can be drawn off therefrom.
  • FIG. 6 This cross-sectional view in FIG. 6 also illustrates the steam over-flow or return lines 8 which lead over con-
  • the described arrangements of the condenser and low pressure turbines in a cylindrical housing thus provides a very compact and stable type of construction which eliminates high foundations and long exhaust lines for the turbine steam.
  • the cylindrical configuration provides a good pressure-tightness for the housing.
  • a steam turbine installation comprising low pres-' sure turbine means having a rotor mounted on a shaft and surrounded by a cylindrical turbine housing concentric with the shaft, at least one bearing supporting the shaft, a pressure tight outer housing surrounding the turbine housing and concentric with the shaft, the outer housing having continuous walls supporting the bearing, an external foundation supporting the outer housing, formed in the annulus between the turbine housing and the outer housing in respective arcuate segments of the annulus on each side of the turbine a respective condenser section comprising a plurality of condenser tubes means adjacent the condenser tubes for exhausting steam from the turbine directly into contact with the condenser tubes, and the outer housing having a removable segment of a generally V- shaped cross-sectional configuration with the apex of the V being disposed closest to the rotor shaft, the segment extending along the axial length of the outer housing, having V-shaped walls at its ends and being at least as wide as the turbine housing diameter.
  • a steam turbine installation according to claim 1 further comprising low-pressure preheaters disposed within said outer housing below said turbine means.
