Definitions

  • This invention relates to foundations for turbogenerator power plants, and in particular, to an oil lubricating system for the turbine and generator units disposed integral with the foundation itself.
  • the turbogenerator unit usually includes a high-pressure turbine element connected to an intermediate or low pressure turbine element, the turbines providing rota-' tional mechanical energy for an electric generator element.
  • the elements which would comprise the turbogenerator are usually disposed in an end-to-end configuration on an operating floor supported away from a lower floor level by the reinforced concrete foundation.
  • a floating barge unit is an integrated power plant facility which will provide electrical energy to coastal cit ies.
  • the barge unit will be disposed within a large breakwater structure and the entire plant, including nuclear reactor facility, is to be located approximately three to five miles off-shore of the coastal areas. Power generated in these barge units will be utilized by the high-density urban areas along the seaboard, areas where expansion of traditional land-based power generating units, whether nuclear or fossil fuel, is limited because of environmental or safety considerations. It is evident that efficient utilization of space on the barge unit is a necessity both to increase the operating efficiency of the barge unit, and to decrease the cost factor involved in fabricating such a large, floating power plant.
  • the conduit system requires not only that piping necessary to conduct the lubricating fluid to and from the user apparatus be provided, but also requires a guard pipe" arrangement to protect the turbogenerator apparatus from damage if rupture occurs to the influent or effluent piping.
  • the layout of power generating facilities follows a right hand-left hand configuration.
  • the steam systern conduits usually occupy the right hand side of the associated elements, while the necessary lubricating conduits occupy the left hand side of the interconnected elements.
  • Such a disposition is mandated by both space and safety considerations.
  • the guard pipe is disposed to surround both the vertical conduits extending between the reservoir and the operating units, and also surrounds the piping for a horizontal distance on the operating floor.
  • the guard pipe extends horizontally only in the area of the turbogenerator, since economic considerations preclude further guard piping in the area of the generator unit.
  • This invention provides a foundation structure for a turbogenerator power plant fabricated of a plurality of structural steel box beams having a lubricating oil reservoir disposed integral with the steel foundation within the box beams.
  • the box beams are disposed within the foundation for the turbogenerator plant itself and provide a storage volume for the disposition of lubricating fluid therein.
  • Associated conduit means for conducting the fluid lubricant from within the storage volume within the box beam to the associated turbine and generator elements for the power plant are disposed within the storage volume.
  • Suitable pumping means for pumping the lubricant fluid to the turbine and generator elements of the power plant are disposed on the foundation.
  • FIG. 1 is a plan view of a support foundation for a steam turbine power plant embodying the teachings of this invention
  • FIG. 2 is a perspective view of a box beam member utilized by a support foundation for a steam turbine power plant embodying the teachings of the invention
  • FIG. 3 is an elevation view of a support foundation for a steam turbine power plant taken along lines III- III of FIG. 1;
  • FIG. 4 is a perspective view of a floating barge power generation facility utilizing a support foundation embodying the teachings of the invention.
  • FIG. 1 a plan view of a turbogenerator power plant having a foundation l2 fabricated of a plurality of structural steel box beams 14 and supporting a predetermined number of turbogenerator elements thereon is shown.
  • the foundation 12 is shown as providing support for a high-pressure turbine element 16, and three low-pressure turbine elements 18, and 22.
  • the turbine elements 16, 18, and 20 and 22 are interconnected by steam conduit means 24.
  • the turbine elements 16, 18, 20 and 22 have a common shaft 26 which is connected in a driving relationship to a generator element 28 mounted on the foundation 12. All turbine elements and generating equipment are mounted upon suitable seating plates 30 disposed on the foundation 12.
  • the turbine elements convert high-pressure high-temperature steam into rotational mechanical energy which turns a rotor member disposed within the generator element 28 to provide electrical energy for an associated electrical load (not shown).
  • FIG. 2 a view of a structural steel box beam 14 which comprise the foundation 12 of the power plant 10 is shown.
  • the structural steel box beam 14 shown in FIG. 2 is a substantially rectangular member fabricated of two side plates 32 and 34, a cover plate 36 and a base plate 38.
  • a longitudinal stiffener member 40 and a plurality of transverse stiffener members 42 are disposed within the box beam 14.
  • the stiffeners provide the box beam 14 with a honeycomb construction, when viewed in plan, as indicated by reference numeral 44 in FIG. 1. It is also noted that any predetermined number of longitudinal stiffeners 40 and transverse stiffeners 42 may be used between side plates 32 and 34 to provide any individual box beam with any predetermined dimension.
  • the foundation construction near the generator end 46 of the power plant that is, near the right hand edge as shown in FIG. 1, is required to be wider than the foundation construction along the side walls, as indicated near reference numeral 48 in FIG. 1. Accordingly, a greater number of longitudinal stiffeners are disposed between side plates used to construct the foundation near the end 46 than are used to construct the foundation near the side walls at 48.
  • each stiffener member 40 or 42 normally extends fully between the cover plate 36 and the base plate 38 when fabricated to provide the honeycomb, a predetermined number of the transverse stiffeners 42 do not fully extend between the cover plate 36 and the base plate 38.
  • the volumes of several adjacent cells communicate with each other through channels 52 provided by the shortened stiffeners to provide an extended storage volume 54 disposed within the individual box beam 14.
  • the storage volume 54 may be totally enclosed by providing full stiffener members 42A.
  • the longitudinal stiffener member 40 may itself have a cut out, or channel therein, to increase the capacity of the storage volume 54 defined within the box beams 14.
  • FIG. 1 indicates the oil reservoir is between stiffeners 42A on one side of the foundation 10, the reservoir may be split into compartments and a compartment disposed on each side of the foundation. Such a disposition of reservoir volume tends to evenly distribute stresses imposed by the lubricating fluid on the foundation.
  • FIG. 3 an elevational view of the power plant 10 having a foundation 12 fabricated of structural steel box beam members 14 and taken along lines III-III of FIG. 1 is shown.
  • the foundation 12 is shown as supported away from a support plane 60 by seven steel pillar members 62.
  • the pillars 62 are fabricated in a manner similar to that described in connection with FIG. 2.
  • the support plane 60 can be any suitable support member
  • the structural steel foundation 12 fabricated by box beam members 14 is supported by the pillars 62 away from the barge unit 64 (FIG. 4). It is to be understood, however, the teachings of this invention apply to any fossil fuel or nuclear power plant, either on-shore or on a barge unit, which utilizes a box beam foundation.
  • the barge unit 64 itself completely supports the power plant 10 mounted on the foundation 12 and an associated steam supply facility 68 within a protective breakwater 70.
  • the protective breakwater 70 is located a predetermined distance off-shore in coastal waters and provides an integrated power plant facility for the generation of electrical energy utilized by large urban concentrations located geographically adjacent to the coast. It is seen from FIG. 4 that space within the barge unit 64 is a valuable commodity and thatefficient use of the available space is reflected in decreased overall cost of individual power generating barge units 64.
  • the lubricating system comprised an oil reservoir usually disposed below the operating level of the turbine and generator elements and disposed on elaborate and extensive conduit network to provide fluid lubrication to the bearings and other portions of the power plant which required lubrication.
  • a predetermined number of box beam members 14 disposed within the structural steel foundation 12 of the power plant 10 is partitioned by suitable stiffener members 42A so as to segregate the predetermined continuous. storage volume 54defined by adjacent cells 50 in the honeycomb structure of the foundation 12 itself.
  • Conduit means 72 provide a continuous flow of fluid lubricant from the integral oil'reservoir within the box beam members 14 to'the bearings and other portions of the turbine and generator elements which require lubrication.
  • the flow of fluid lubricant to and from the bearing members are indicated by flow arrows 74 and 76.
  • the flow into and out of the bearing members being provided by pumping means 78 disposed on the struc-' tural steel foundation 12.
  • a lubricant cooling facility 80 is provided on the structural steel foundation 12.
  • the disposition of the fluid lubricant reservoir 54 within the storage volume generated by the communication of several volumes of cells 50 within the box beam members 14 provides advantages over the separate oil reservoir structure of the prior art in addition to the obvious space saving feature of an oil reservoir integral with the structural steel foundation 12.
  • the oil reservoir is typically located approximately 30 to 50 feet below the User apparatus. Since this is the case, an extensive exposed conduit network and the associated hangers and conduit supports is required to interconnect the oil reservoir to the user apparatus. In addition, extra exposed conduit is required due to the right hand-left hand configuration of the prior art.
  • the right hand-left hand configuration refers to the disposition of steam interconnections on either the right or the left side of the power plant when viewing the turbogenerator toward ficient exposed conduit in order to interconnect the separate oil reservoir from the bearings and other lubricant requiring sections of the turbine generator.
  • guard pipe In addition to conduit necessary to carry the influent and effluent lubricating fluid to the oil requiring portions of the turbine generator, a guard pipe is necessary in order to protect against the danger of rupture of the conduits
  • the guard pipe surrounds those vertical portions of the conduits between the oil reservoir and the .foundation, and extends around the horizontal portions of the conduits in the area of the turbine elements. No guard-pipe is provided in the area of the generator elements in the prior art.
  • a lubrication system embodying the teachings of this invention and having an oil reservoir disposed within the box beam members 14 eliminates all of the aforementioned disadvantages of the prior art.
  • the conduits 72 are disposed completely within the hollow volumes 54 within the box beam members 14. No external hangers or support members are required and no guard pipe'is necessary. Since the conduits are completely surrounded by the box beam member 14, protection against any rupture of the conduit members 72 is provided.
  • conduits 74 providing lubricant to the generator element 28 are surrounded by the box beam members 14 adjacent the generator element 28 and provide a function similar to a guard pipe function which was not available in the prior art. Since the conduits are within the structure of the foundation 12 itself, access to and repair of the conduits in event of the rupture is facilitated. Also, the internal conduit 72 may be prefabricated into the structure of the box beam members 72 themselves, again generatinga substantial cost savings.
  • the oil reservoir disposed within the volume 54 within the box beam members 14 is a predetermined distance 82 beneath the centerline of the turbine generator elements.
  • the distance 82 is on the order of -108 inches, thus reducing the energy requirement that must be expended to conduct lubricating fluid from the reservoir to the bearings. Since this is so, the associated pump means 78 require less energy from the power plant 10, increasing the efficiency of the power plant 10.
  • the suction pump mounted on the rotating shaft is sufficient to maintain the flow of fluid lubricant to the bearings without the necessity of auxiliary pumping means.
  • a power plant 10 having an integral oil reservoir embodying the teachings of this invention reduces the amount of oil necessary to be maintained within the integral reservoir to meet the appropriate standards.
  • an oil reservoir 54 within the central volume of the box beam members 14 of a structural steel foundation 12 provides a more efficient, safer and cheaper power plant than is available in the prior art.
  • the integral oil reservoir so defined provides a more efficient, safer, and less costly power plant foundation 12 for use on floating barge unit power plants.
  • the steam turbine power plant comprising:
  • a foundation supporting thereon a steam turbine element said foundation being fabricated of structural steel box beams, said box beams providing a storage volume therein,
  • stiffener members defining a lubricant reservoir within said storage volume, a supply of fluid lubricant being disposed within said reservoir defined between said stiffener members.
  • conduit means for conducting fluid lubricant from said reservoir to said turbine element, said conduit means being disposed within said storage volume provided within said structural steel box beams.
  • a lubrication system for said electrical generator element is disposed integral with said foundation, said lubrication system for said electrical generator element comprises conduit means for conducting fluid lubricant from said reservoir to said electrical generator element, said conduit means for said electrical generator element being disposed within said storage volume provided within structural steel box beams.
  • said lubricant reservoir being defined by said stiffener members within each storage volume within each sidewall, theaxis the axis each reservoir being substantially parallel to the axis extending through said turbine element.
  • said lubrication system for said turbine comprises conduit means for conducting fluid lubricant from said reservoir within each sidewall to said turbine element, said conduit means being disposed within said storage volumes provided within each sidewall.
  • a lubrication system for side electrical generator element is disposed integral with said foundation, said lubrication system for said electrical generator element comprises conduit means for conducting fluid from said reservoir within each sidewall to said generator element, said conduit means being disposed within said storage volumes provided within each sidewall.
  • fluid lubricant cooling means associated with said conduit means and said pump means for cooling said lubricant
  • both said pump means and said cooling means being disposed on said foundation adjacent said turbine element.
