Definitions

  • the present invention relates to a moisture separator reheater for generating superheated steam by separating moisture from steam and heating the steam.
  • the present invention is extremely effective in nuclear power plants when implemented for utilizing steam that has been used in a high-pressure steam turbine, again in low-pressure steam turbines.
  • a moisture separator reheater is used which generates superheated steam by separating moisture from the steam discharged from the high-pressure steam turbine (moisture content is reduced to approximately 0.1%) and heating the steam, and which feeds the superheated steam to the low-pressure steam turbines.
  • a two-stage reheat one has been known, for example, such as described in Patent Document 1 below.
  • steam from a high-pressure steam turbine flows into a steam receiving chamber in a horizontal and cylindrical shell body through a steam receiving opening provided in a lower central portion of the shell body, collides with a baffle plate, divides into two directions toward two axial end sides of the shell body to rise, flows into supply manifold chambers provided on each of the two axial end sides of the shell body, flows into moisture separation chambers through slits of distributor plates, and undergoes moisture separation in mist separators.
  • the steam from which moisture has been separated flows into a heating chamber provided in a portion containing the central axis of the shell body, undergoes first-stage heating in first-stage heater tube groups and then second-stage heating in second-stage heater tube groups, and is thereafter sent out to a low-pressure steam turbine from a steam delivery opening provided in an axially central portion of an upper portion of the shell body.
  • PATENT DOCUMENT 1 JP-A-7-301691
  • a heating chamber provided in a portion containing the central axis of a shell body is divided into two chambers on two axial end sides of the shell body.
  • a collection manifold chamber communicating throughout the axial length of the shell body is provided.
  • a partition plate is provided in a way to separate the respective sections of the collection manifold chamber and the steam receiving chamber.
  • a plurality of (e.g., three) steam delivery openings in an upper portion of the shell body are provided in the axial direction of the shell body.
  • the steam receiving chamber through which low-temperature steam circulates and the collection manifold chamber through which high-temperature steam circulates are adjacent to each other with the partition plate interposed therebetween. Accordingly, pre-reheated steam fed into the steam receiving chamber decreases the temperature of steam near the partition plate, i.e., in a space part, adjacent to the steam receiving chamber, in the collection manifold chamber.
  • the temperature of steam sent out from the steam delivery opening located above the partition plate i.e., located in an axially central portion of the shell body and connected to a space part adjacent to the steam receiving chamber, is lower than the temperature of steam sent out from the steam delivery openings located on the two axial end sides of the shell body. Accordingly, there is the problem of the decrease in thermal efficiency of a low-pressure steam turbine fed with the steam from the steam delivery opening located in the axially central portion of the shell body.
  • an object of the present invention is to provide a moisture separator reheater which can prevent a decrease in temperature of steam sent out.

  • the moisture separator reheater is characterized by comprising heat-conduction reducing means for reducing heat conduction between the adjacent sections respectively of the steam receiving chamber and the collection manifold chamber of the shell body.
  • a moisture separator reheater is characterized in that in the first invention, the heat-conduction reducing means is a hollow partition member disposed to separate the adjacent sections respectively of the steam receiving chamber and the collection manifold chamber, and the partition member has communicating holes allowing the collection manifold chamber and an inside of the partition member to communicate with each other so as to receive therein the steam circulating in the collection manifold chamber and to return the received steam to the collection manifold chamber.
  • a moisture separator reheater is characterized in that in the first invention, the heat-conduction reducing means is a partition member which has a heat insulating layer therein and which is disposed to separate the adjacent sections respectively of the steam receiving chamber and the collection manifold chamber.
  • a moisture separator reheater is characterized in that in the first invention, the heat-conduction reducing means is an arrangement of the steam discharge opening, and the steam discharge opening is connected only to a space part of the collection manifold chamber other than a space part adjacent to the steam receiving chamber.
  • a moisture separator reheater since the heat-conduction reducing means reduces the heat conduction between the adjacent sections respectively of the steam receiving chamber and the collection manifold chamber of the shell body, a decrease in temperature of steam sent out from a steam delivery opening can be prevented.
