Moisture separator reheater

Abstract

A moisture separator reheater ( 100 ) includes a shell body ( 111 ) having provided therein a steam receiving chamber ( 111 a ) having steam receiving openings ( 112 a , 112 b ) for receiving steam ( 1 ), a supply manifold chamber ( 111 b ) communicating with the steam receiving chamber ( 111 a ), a moisture separation chamber ( 111 c ) communicating with the supply manifold chamber ( 111 b ) and separating moisture from the steam ( 1 ), a heating chamber ( 111 d ) communicating with the moisture separation chamber ( 111 c ) and heating the steam ( 1 ), and a collection manifold chamber ( 111 e ) being disposed adjacent to the steam receiving chamber ( 111 a ), communicating with the heating chamber ( 111 d ), and having steam discharge openings ( 120 a to 120 c ) for discharging the steam ( 1 ). The moisture separator reheater ( 100 ) further includes heat-conduction reducing means for reducing heat conduction between the adjacent sections respectively of the steam receiving chamber ( 111 a ) and the collection manifold chamber ( 111 e ) of the shell body ( 111 ).

1 . A moisture separator reheater including a shell body provided inside with:
 a steam receiving chamber having a steam receiving opening for receiving steam;   a supply manifold chamber communicating with the steam receiving chamber;   a moisture separation chamber communicating with the supply manifold chamber and separating moisture from the steam;   a heating chamber communicating with the moisture separation chamber and heating the steam; and   a collection manifold chamber being disposed adjacent to the steam receiving chamber, communicating with the heating chamber, and having a steam discharge opening for discharging the steam,   the moisture separator reheater 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.   
     
     
         2 . The moisture separator reheater according to  claim 1 , wherein
 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.   
     
     
         3 . The moisture separator reheater according to  claim 1 , wherein
 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.   
     
     
         4 . The moisture separator reheater according to  claim 1 , wherein
 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.
