  • the low pressure moisture separating heater 28 includes the two low pressure moisture separating heaters 28a and 28b, and they are disposed on the floor 61 so as to be positioned on both sides in the width direction of the high and intermediate pressure turbine 21, symmetrically with respect to the center line in the axial direction C.
  • the one high pressure moisture separating heater 27 is disposed on the side opposite to the low pressure turbine 22 in the axial direction C of the high and intermediate pressure turbine 21.
  • the high pressure moisture separating heater 27 is disposed on the floor 61 along the axial direction C adjacent to the high and intermediate pressure turbine 21.

  • the high pressure moisture separating heater 27 is disposed along the axial direction C of the high and intermediate pressure turbine 21. Therefore, it is possible to effectively utilize the space in the longitudinal direction of the high pressure moisture separating heater 27 and the low pressure moisture separating heater 28.
  • FIG. 8 is a plan view showing an arrangement of a steam turbine plant according to a third embodiment. Note that members having the same functions as those in the above-described embodiment are denoted by the same reference numerals, and a detailed description thereof will be omitted.

  • the high pressure moisture separating heater 27 includes the two high pressure moisture separating heaters 27a and 27b, and they are disposed on the side opposite to the low pressure turbine 22 in the axial direction C of the high and intermediate pressure turbine 21.
  • the high pressure moisture separating heaters 27a and 27b are disposed on the floor 61 along the direction intersecting the axial direction C while being adjacent to the high and intermediate pressure turbine 21, and moreover, the high pressure moisture separating heaters 27a and 27b are disposed symmetrically with respect to the center line in the axial direction C.
  • the plurality of (two in the present embodiment) high pressure moisture separating heaters 27a and 27b are disposed in parallel at a predetermined interval.
  • the two high pressure moisture separating heaters 27a and 27b as the high pressure moisture separating heater 27 are disposed in parallel, and also the high pressure moisture separating heaters 27a and 27b are disposed symmetrically with respect to the center line in the axial direction C while intersecting the center line. Therefore, by disposing the high pressure moisture separating heater 27 and the low pressure moisture separating heater 28 in an intersecting manner to effectively utilize the space, it is possible to downsize the turbine building, and to process the steam from the high pressure turbine unit 25 in a well-balanced manner.
  • FIG. 9 is a plan view showing an arrangement of a steam turbine plant of a fourth embodiment. Note that members having the same functions as those in the above-described embodiment are denoted by the same reference numerals, and a detailed description thereof will be omitted.
  • the steam turbine plant of the fourth embodiment includes the high and intermediate pressure turbine 21, the low pressure turbine 22, the pipe 31, the high pressure moisture separating heater 27, and the low pressure moisture separating heater 28.
  • the low pressure moisture separating heater 28 includes the two low pressure moisture separating heaters 28a and 28b, and they are disposed on the floor 61 so as to be positioned symmetrically on both sides in the width direction of the high and intermediate pressure turbine 21.

  • the high pressure moisture separating heater 27 is disposed on the floor 61 along the direction intersecting the axial direction C while being adjacent to the high and intermediate pressure turbine 21, and moreover, the high pressure moisture separating heater 27 is disposed symmetrically with respect to the center line in the axial direction C.
  • the deaerator 47 is disposed adjacent and in parallel to the high pressure moisture separating heater 27.
  • the one high pressure moisture separating heater 27 is disposed symmetrically with respect to the center line in the axial direction C while intersecting the center line. Therefore, by effectively utilizing the space in the axial direction, it is possible to downsize the turbine building, and to process the steam from the high pressure turbine unit 25 in a well-balanced manner.
  • the four low pressure feed water heaters 43, 44, 45, and 46 are provided, of which the two low pressure feed water heaters 43 and 44 are disposed in the condensers 33 and 34, and the two low pressure feed water heaters 45 and 46 are disposed outside the condensers 33 and 34.
  • the arrangement and the number of low pressure feed water heaters are not limited to those of the embodiments, and they may be set appropriately according to the scale of the steam turbine plant or the like.
  • the steam exhausted from the final stage of the intermediate pressure turbine unit 26 is supplied to the low pressure moisture separating heater 28 (28a and 28b); however, the steam extracted from the middle stage of the intermediate pressure turbine unit 26 may be supplied to the low pressure moisture separating heater 28 (28a and 28b).
  • the moisture separating heater has been described, but it may be a moisture separator.
  • the steam turbine plant of the present invention is applied to a nuclear power plant; however, the present invention is not limited thereto, and for example, the present invention can be applied to a thermal power plant or the like.
