Definitions

  • the present invention relates to a steam turbine installation with withdrawal adjusted to a determined pressure.
  • the racking is carried out in accordance with the diagram of Figure 1. Taking this figure for example, we can see that the racking is performs through an outlet S located between the sixth stage P and the seventh stage Q and that the regulating valve R making it possible to maintain the withdrawal pressure constant, is also located between the sixth and the seventh stage.
  • This arrangement is bulky and lengthens the turbine by a length corresponding to at least three stages, as can be seen in FIG. 1.
  • the present invention thus relates to a steam turbine installation with withdrawal adjusted to a determined pressure, driving a receiving member, comprising a withdrawal outlet disposed between two successive stages, characterized in that the withdrawal pressure P is adjusted, in a certain range D of the draw-off flow, by means of a servo-valve arranged on the exhaust pipe and controlled from a control circuit comprising a means for measuring the pressure of the draw-off flow.
  • the turbine is composed of two separate bodies, said draw-off outlet being arranged between two successive stages of the first body and said servo-valve being disposed on the exhaust pipe of said first body.
  • the installation shown comprises a steam turbine 1 mounted between two bearings 2 and 3.
  • the turbine drives an alternator 4 via a reduction gear 5.
  • a pipe 6 provided with a valve 7 supplies the turbine, the exhaust of which is connected to a condenser 8 by a pipe 9.
  • the turbine comprises seven stages, and a withdrawal pipe 10 terminates within the turbine between the fifth and the sixth stage.
  • the exhaust pipe 9 is provided with a servo-valve 11.
  • This servo-valve 11 is controlled from a control circuit 12 comprising means for comparing a setpoint signal coming from a setpoint generator 13 and a signal coming from a pressure probe 14 located in the draw-off line 10.
  • the invention makes it possible to separate in space the functions of racking and adjusting the racking pressure thereby reducing the length of the rotary mobile.
  • FIG. 3 shows a particularly interesting example of the invention which is the case of a multi-body cantilever turbine.
  • the installation shown comprises a steam turbine made up of two bodies 20 and 21 mounted cantilevered.
  • the high pressure body 20 is connected to the low pressure body 21 by its exhaust pipe 22.
  • the two bodies 21 and 22 drive in parallel a reduction gear 23 whose output shaft drives a receiver 24, for example an alternator.
  • the low pressure body 21 escapes in a condenser 25.
  • the high pressure body 20 is supplied by a pipe inlet 26, provided with an inlet valve 33, from a boiler.
  • a withdrawal line 27 terminates within the high pressure body 2 between two expansion stages, between the third and the fourth stage in the example shown. This withdrawal is adjusted to a determined pressure P.
  • the exhaust pipe 22 of the first body 20 is provided with a servo-valve 28.
  • the servo-valve 28 is controlled from a servo circuit 29 comprising means for comparing a setpoint signal coming from a setpoint generator 30 and a signal coming from a pressure probe 31 located in the withdrawal line 27.
  • the installation shown also includes a second unregulated withdrawal 32 taken downstream of the first stage of the low pressure body 21.
  • the adjustment system 28 will generally be a system with several valves supplying separate injection sectors.
