Definitions

  • This invention relates to a cooling arrangement for elastic fluid axial flow turbines. More particularly, the invention relates to an arrangement for reducing the possiblity of overheating or distorting the turbine parts with hot leakage fluid in the spaces between turbine wheels and sationary diaphragms.
  • leakage fluid from various sources may be significantly diiferent in temperature than the main steam flow.
  • fluid passing through the turbine at inner and outer boundaries of the annulus where fluid losses are greatest will become hotter than the fluid passing through the central portion of the flow path.
  • the result may be unequal heat or overheating of the Wheel spaces between the Wheels and diaphragms. This overheating can cause diaphragm distortion, extra leak age and rubbing, rotor bowing, and other undesirable phenomena.
  • one object of the present invention is to provide an arrangement for reducing overheating of the inner wheel and diaphragm spaces of a turbine, as well as reducing energy losses in the flow of leakage fluid.
  • Another object of the invention is to provide an im proved structure for recovering energy in the motive fluid which escapes through the balance holes of steam turbine wheels.
  • the invention is practiced by providing collecting passages in the Working steam path at a convenient location, such as on the leading edge of a downstream nozzle partition, and providing passages to conduct this cooler steam to the space between the diaphragm and an upstream turbine wheel.
  • a portion of this cooling steam replenishes the inherent leakage flow around the labyrinth seal between diaphragm and shaft.
  • the other portion of the steam serves to deflect hot leakage steam outward into the working steam path Where its energy can be recovered.
  • FIG. 1 is a horizontal elevation drawing, partly in section, of a multistage axial flow steam turbine, showing portions of two diaphragms and two turbine wheels, and
  • FIG. 2 is a cross-sectional view of a stationary nozzle partition, taken along lines IIII of FIG. 1.
  • the turbine includes a casing, a portion of which is shown generally at 1, and a rotor, a portion of which is shown generally at 2. Only two steam turbine stages are shown in the drawing, since it will be understood by those skilled in the art that the remainder of the turbine necessarily includes means for introducing steam at the high pressure end through suitable inlet passages, and that the turbine also includes means for either an exhaust hood or for an outlet passage conducting the steam to another turbine section.
  • the turbine rotor 2 includes an inner shaft portion 3 and a series of turbine wheels such as 4, 5 which may be formed integrally with shaft 3 from a single forging. Secured to the circuferences of turbine wheels 4, 5 are a series of spaced buckets or blades 6, 7 surrounded by shroud bands 8.
  • Stationary diaphragms 9, 10 are supported in casing 1 and associated with wheels 4, 5 respectively for directing the working elastic fluid, such as steam, to the buckets.
  • These diaphragms are in the form of annular disk members and include solid inner webs 11, 12 and rings of circumferentially spaced blades or nozzle partitions 13, 14 forming nozzle passages between them.
  • labyrinth packings 15 Arranged around the central openings in the diaphragms and cooperating with shaft 3 are labyrinth packings 15 which limit the flow of steam through the clearance spaces between the shaft 3 and the respective diaphragms.
  • pressure balancing holes such as 16, 17 are often provided through the web portions of the respective wheels.
  • the invention is also useful in turbine stages which do not employ balance holes.
  • Diaphragm web 12 includes an intengral axially projecting lip 23 which is positioned opposite an outlet 16a of balance port 16.
  • a means for introducing cooling steam into wheel space 21 is provided by means of collecting slots 27 in the leading edges of selected nozzle partitions 14. Slots 27 interconnect with radial passages such as 28 through the partition or blade itself which, in turn, interconnect with larger inwardly directed passages 29 in the web 12 of the diaphragm. Slot 27 and interconnected passages 28, 29 act as a collection and diffusing conduit to collect working steam after it has been expanded through (and therefore cooled by) the upstream bucket 6 and for directing this cooler steam inwardly to the wheel space 21. It should be particularly noted that since the steam arriving at space 21 has been expanded through turbine bucket 6, it will be cooler than the higher energy steam in the upstream wheel space chamber 18 which normally would pass through balance holes 16 into chamber 21.
  • the top view of blade 14 illustrates a suitable means for providing the collecting slot 27, wherein it is seen that this is simply milled into the leading edge of nozzle blade 14 so as to intersect a hole 28 slanting upward from the base of the nozzle blade.
  • the collected steam issuing from passage 29 is divided into two portions. A portion of this flow passes radially outward through the annular passage 22 and, in so doing further deflects the hot leakage steam issuing from balance hole outlets 16a into the working fluid path. The other portion of the cool steam flows radially inward, and past the layb-yrinth packing 15 into wheel space 24. In wheel space 24 this leakage steam is now hotter, relatively speaking, than steam which has been expanded through the next stage of turbine blades 7, and the cycle is repeated.
  • Cool flow discharging from holes 29 can again prevent this hot flow from another cycle of leakage and greater temperature difference with the working fluid in the same way described above for stages with balance holes.
  • the foregoing system aids greatly in reducing diaphragm distortions, since, at each stage, the cooling fluid for the inner diaphragm is collected at that particular location of the turbine. Therefore, there is no necessity for controlling cooling from an external source, this being automatically achieved with the arrangement described.
  • a turbine wheel portion extending radially from a rotatable shaft portion, said wheel portion having a plurality of turbine buckets on its periphery,
  • a stationary annular diaphragm member having a plurality of nozzle partitions thereon disposed to receive fluid from said :buckets, said diaphragm member also including packing means closely surrounding the shaft portion, and
  • a turbine wheel portion extending radially from a rotatable shaft portion, said wheel portion having a plurality of turbine buckets on its periphery and also defining balance passages therethrough having outlets,
  • a stationary annular diaphragm member having a plurality of nozzle partitions thereon disposed to receive fluid from said buckets, said diaphragm member also including packing means closely surrounding the shaft portion, and
  • each of said cooling fluid passage inlets comprises a collecting slot defined in the lea-ding edge of selected nozzle partitions on the diaphragm.
  • a rotor having a shaft with a plurality of axially spaced turbine wheels, each with a circumferential row of buckets for extracting energy [from working fluid and defining at least one pressure balancing passage through the wheel having an outlet discharging leakage fluid at a location radially inward from the buckets,
  • nozzle diaphragms disposed in the spaces between the respective turbine wheels and each having a plurality of circumferentially spaced nozzle partitions and also having packing means surrounding the shaft and defining a restricted fluid flow path from one side of the diaphragm to the other, and
  • each of said diaphragms defines an annular lip disposed adjacent the outlet of the pressure balance passage of the said cooling fluid in deflecting leakage fluid into the Working fluid path.
