摘要:
A moisture separator heater includes: a casing having a tubular shape, extending in a horizontal direction and having both end portions closed; a manifold chamber provided in the casing and configured so that steam flows in an axial direction of the casing; a separator provided in the casing and in a longitudinal direction of the casing along the manifold chamber and configured to remove moisture in the steam; and a heating tube bundle provided in the casing and on a downstream side of the steam flowing out of the separator. The heating tube bundle has a polygonal shape in a lateral view and has a longitudinal edge extending along the axial direction of the casing and a transverse edge extending in a vertical direction.
摘要:
Performance of a moisture separator and a steam turbine plant is improved without increase in the size and the manufacturing cost thereof, by provision therein of: a body (31) that has a hollow shape and extends in a horizontal direction; a steam inlet portion (32) that is provided in a longitudinally intermediate portion of the body (31); a manifold (35, 36) that is arranged with a predetermined gap from an inner wall surface of the body (31), has a longitudinally intermediate portion communicating with the steam inlet portion (32), and has plural steam blowout portions (53, 54) provided along a longitudinal direction; moisture separating elements (37, 38) that separate moisture from steam blown out from the plural steam blowout portions (53, 54); and steam outlet portions (33, 34) which are provided in the body (31) and through which the steam is discharged, the steam having had the moisture separated therefrom and flowing along an inner wall of the body (31).
摘要:
A steam turbine plant equipped with: a high-intermediate pressure turbine (21) at one end of which in the axial direction a high-pressure turbine unit (25) is provided, and at the other end of which an intermediate-pressure turbine unit (26) is provided; low-pressure turbines (22, 23) arranged coaxially with the high-intermediate pressure turbine (21); condensers (33, 34) that cool steam used in the low-pressure turbines (22, 23), thereby condensing the steam and converting the steam to condensate water; and a second high-pressure water supply heater (50) that heats the condensate water by means of steam discharged from the high-pressure turbine unit (25).
摘要:
Provided is a moisture separation unit including a cylindrical low-pressure moisture separator-heater (28) that removes moisture from steam discharged from a high-and-intermediate-pressure turbine (21), a steam pipe (31) that is connected to an end portion in a first direction (D1) of the low-pressure moisture separator-heater (28) to introduce steam from the high-and-intermediate-pressure turbine (21) into the low-pressure moisture separator-heater (28), and a steam pipe (32) that is extended from the low-pressure moisture separator-heater (28) in a second direction (D2) to feed the steam via the low-pressure moisture separator-heater (28) to low-pressure turbines (22, 23).
