Desuperheaters having vortex suppression

Abstract

Desuperheaters having vortex suppression are described herein. An example desuperheater includes a body portion having a passageway to provide cooling water to a fluid flow path and vortex suppression device adjacent an end of the body. The vortex suppression device is disposed within the fluid flow path to attenuate or suppress vortex shedding or flow induced vibrations imparted on the desuperheater by a fluid in the fluid flow path.

1 . A desuperheater comprising:
 a body portion having a passageway to provide cooling water to a fluid flow path; and   a vortex suppression device adjacent an end of the body, the vortex suppression device to be disposed within the fluid flow path to attenuate or suppress vortex shedding or flow induced vibrations imparted on the desuperheater by a fluid in the fluid flow path.   
     
     
         2 . A desuperheater of  claim 1 , wherein the body portion is coupled to a fluid flow pipeline via a flange. 
     
     
         3 . A desuperheater of  claim 2 , wherein the body portion includes a non-tapered profile between the flange and the end of the body. 
     
     
         4 . A desuperheater of  claim 2 , wherein the body portion is to be suspended substantially perpendicular to the fluid flow path. 
     
     
         5 . A desuperheater of  claim 1 , wherein the vortex suppression device comprises a helical straking adjacent the end of the body. 
     
     
         6 . A desuperheater of  claim 5 , wherein the helical straking is integrally formed with the body via casting. 
     
     
         7 . A desuperheater of  claim 1 , wherein the vortex suppression device comprises a splined surface. 
     
     
         8 . A desuperheater of  claim 7 , wherein the splined surface is integrally formed with the body. 
     
     
         9 . A desuperheater of  claim 1 , wherein the vortex suppression device includes a plurality of protruding surfaces adjacent the end of the body. 
     
     
         10 . A desuperheater of  claim 9 , wherein the plurality of protruding surfaces comprise spherically-shaped protrusions. 
     
     
         11 . A desuperheater of  claim 1 , wherein the fluid comprises superheated steam. 
     
     
         12 . A desuperheater to be coupled to a pipeline, the desuperheater comprising:
 a body having a passageway between a flange at a first end of the body and at least one opening at a recessed portion and adjacent a second end of the body, wherein the body is to be suspended within a fluid flow when the desuperheater is coupled to a fluid flow path via the flange such that the body is substantially perpendicular to the fluid flow and the at least one opening is substantially parallel to the fluid flow; and   a vortex suppression device integrally formed with the body adjacent the second end and the recessed portion, wherein the vortex suppression device is to attenuate or suppress vortex shedding or vortex induced vibrations imparted on the body of the desuperheater by a fluid flowing across the body of the desuperheater.   
     
     
         13 . A desuperheater of  claim 12 , wherein the passageway is to provide cooling water to the fluid flow path. 
     
     
         14 . A desuperheater of  claim 12 , wherein vortex suppression device is coupled to the body via welding. 
     
     
         15 . A desuperheater of  claim 12 , wherein the vortex suppression device comprises a helical straking. 
     
     
         16 . A desuperheater of  claim 12 , wherein the vortex suppression device comprises a plurality of ribs. 
     
     
         17 . A desuperheater of  claim 12 , wherein the vortex suppression device includes a plurality of protruding surfaces adjacent the end of the body. 
     
     
         18 . A desuperheater of  claim 17 , wherein the plurality of protruding surfaces comprise spherically-shaped protrusions. 
     
     
         19 . A desuperheater, comprising;
 means for providing cooling water to a fluid flow path, wherein the means for providing cooling water includes a body to be disposed substantially perpendicular to the fluid flow path; and   means for attenuating vortex shedding or vortex induced vibrations to the means for providing cooling water when the means for providing cooling water is coupled to the fluid flow path, wherein the means for attenuating is integrally formed with the means for providing cooling water.   
     
     
         20 . A desuperheater of  claim 19 , wherein the means for attenuating comprises means for disturbing the fluid flow via a non-linear geometrical shape to reduce formation of a vortex street.
