Definitions

  • the disclosed concept pertains generally to a steam generator, and in particular to a steam generator including anti-vibration bars.
  • the disclosed concept also pertains to a method of securing tubes in a steam generator against vibration with a number of anti-vibration bars.
  • a steam generator generally comprises a vertically oriented shell, a tube bundle formed of tubes which each comprise two vertical components that meet at a bend portion, a tube sheet for supporting the tubes at the ends opposite the bend portion, a dividing plate that cooperates with the tube sheet and a hemispheric channel head to form a primary fluid inlet header at one end of the tube bundle and a primary fluid outlet header at the other end of the tube bundle.
  • a primary fluid inlet nozzle is in fluid communication with the primary fluid inlet header and a primary fluid outlet nozzle is in fluid communication with the primary fluid outlet header.
  • the steam generator secondary side comprises a wrapper disposed between the tube bundle and the shell to form an annular chamber made up of the shell on the outside and the wrapper on the inside, and a feedwater ring disposed above the bend portion of the tube bundle.
  • the primary fluid having been heated by circulation through the reactor core enters the steam generator through the primary fluid inlet nozzle. From the primary fluid inlet nozzle, the primary fluid is conducted through the primary fluid inlet header, through the inside of the tube bundle, out the primary fluid outlet header, through the primary fluid outlet nozzle to the reactor coolant pump for recirculation. At the same time, feedwater is introduced to the steam generator secondary side through a feedwater nozzle which is connected to the feedwater ring inside the steam generator. Upon entering the steam generator, the feedwater mixes with water returning from moisture separators positioned above the tube bundle referred to as the recirculation stream.
  • This mixture is conducted down the annular chamber between the shell and the wrapper until the tube sheet near the bottom of the annular chamber causes the water to change direction, passing in heat exchange relationship with the outside of the tubes and up through the inside of the wrapper. While the water is circulating in heat exchange relationship with the tube bundle, heat is transferred from the primary fluid in the tubes to the water surrounding the tubes, causing a portion of the water outside the tubes to be converted to steam.
  • the steam-water mixture then rises and is conducted through a number of moisture separators that separate any entrained water from the steam, and the steam vapor then exits the steam generator and is circulated typically through a turbine generator to generate electricity in a manner well known in the art.
  • the portion of the steam generator primarily including the bend portion of the tubes and below to the channel head is typically referred to as the evaporator section.
  • the portion of the steam generator above the tubes that includes the moisture separators is typically referred to as the steam drum.
  • Feedwater enters the steam generator through an inlet nozzle which is disposed in the upper portion of the cylindrical shell. The feedwater is distributed and mixed with water removed by the moisture separators and then flows down the annular channel surrounding the tube bundle.
  • the tubes are supported at their open ends by conventional means whereby the ends of the tubes are welded to the tube sheet which is disposed generally transverse to the longitudinal axis of the steam generator.
  • a series of tube support plates or grids arranged in an axial spaced relationship to each other are provided along the straight portion of the tubes in order to support the straight section of the tubing.
  • various steam generators utilize different tube configurations, for example wherein the bend portion is curved or U-shaped, or wherein the vertical components of the tubes each bend at sharp angles, forming a relatively horizontal shaped bend portion.
  • a plurality of anti-vibration bars which are typically disposed between each column of tubes.
  • the anti-vibration bars provide support and do not substantially interfere with the flow of the moisture laden steam.
  • the anti-vibration bars are intended to prevent excessive vibrations of the individual tubes of the entire tube bundle; vibrations which can potentially damage the tubes. It is well known that the bend portion of the tube bundle is more severely affected by the vibrations, and, because of the bend configuration, more difficult to adequately support in order to eliminate the vibrations.
  • a steam generator with an anti-vibration bar assembly in accordance with the precharacterizing portion of claim 1 is disclosed in document US 4,893,671 .
  • Another anti-vibration bar design is found in document CH 367 842 wherein the anti-vibration bars are formed as straps having a zig-zag pattern.
  • a steam generator has a primary side for circulating a heated fluid and a secondary side for circulating a fluid to be heated by the heated fluid circulating in the primary side.
  • the steam generator includes: a channel head for receiving the heated fluid; a tube sheet that separates the channel head from the secondary side; a tube bundle having a plurality of tubes, arranged in rows and columns, the tube bundle extending from the channel head, through the tube sheet and through at least a portion of the secondary side; and a first number of solid anti-vibration bars.
  • the plurality of tubes includes a first column of tubes, the first column of tubes comprising a first tube having a curved center line disposed in a first plane.
  • the plurality of tubes further includes a second column of tubes, each of the first number of anti-vibration bars being disposed between the first column of tubes and the second column of tubes.
  • the second column of tubes comprises a second tube having a curved center line disposed in a second plane, the second plane being parallel to and spaced a distance from the first plane.
  • Each of the tubes has a tube outer diameter.
  • Each of the first number of anti-vibration bars has a thickness generally transverse to the first and second planes. The thickness of each of the first number of anti-vibration bars is greater than the distance between the first and second planes minus the tube outer diameter.
  • a method for securing tubes within a steam generator against vibration, the tubes being disposed in a tube bundle and arranged in rows and columns, with lanes between the columns.
  • the method comprises: providing a first column of tubes, the first column of tubes comprising a first tube having a curved center line disposed in a first plane; providing a first number of solid anti-vibration bars; and providing a second column of tubes, each of the first number of anti-vibration bars being disposed between the first column of tubes and the second column of tubes, the second column of tubes comprising a second tube having a curved center line disposed in a second plane, the second plane being parallel to and spaced a distance from the first plane.

  • the top of the wrapper 30 is covered by a lower deck plate 34 which includes a plurality of openings 36 in fluid communication with a plurality of riser tubes 38.

  • Feedwater which is supplied through the feedwater inlet nozzle 46, passes through the feedwater ring 48, exits through the discharge nozzles 50 and mixes with water which was separated from the steam and is recirculated. The mixture then flows down above the lower deck plate 34 into the annular downcomer passage 32. The water then enters the tube bundle 4 at the lower portion of the wrapper 30 and flows among the tubes 3 and up the tube bundle 4 where it is heated to generate steam.
