Definitions

  • Steam supply systems typically produce or generate superheated steam having relatively high temperatures (e.g., temperatures greater than the saturation temperatures) greater than maximum allowable operating temperatures of downstream equipment. In some instances, superheated steam having a temperature greater than the maximum allowable operating temperature of the downstream equipment may damage the downstream equipment.
  • a steam supply system typically employs a desuperheater to reduce or control the temperature of the fluid or steam downstream from the desuperheater.
  • Some known desuperheaters e.g., insertion-style desuperheaters
  • the desuperheater includes a passageway that injects or sprays cooling water into the steam flow to reduce the temperature of the steam flowing downstream from the desuperheater.
  • superheated steam flows at relatively high velocity through the fluid flow path and may undergo an unsteady flow across the body of the desuperheater interposed in the fluid flow path.
  • Such high velocity or unsteady flow may cause vortex shedding, resulting in vortex induce vibrations and/or lift forces that are imparted on the body of the desuperheater and which may cause the body to vibrate.
  • vortex induced vibrations that resonate at frequencies that are substantially similar or identical to a natural frequency of the body of the desuperheater may cause the desuperheater to fracture or otherwise become damaged, thereby reducing the operating life of the desuperheater.
  • an example desuperheater includes a body portion having a passageway to provide cooling water to a fluid flow path a 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.
  • FIG. 1 illustrates a fluid system implemented with a known desuperheater apparatus.
  • FIG. 2A illustrates a fluid system implemented with an example desuperheater having vortex suppression described herein.

  • An example desuperheater described herein may be utilized with a steam supply system to significantly reduce vortex induced vibrations that may be caused by superheated steam flowing at a relatively high velocity (e.g., 300 feet/second) across the desuperheater.
  • an example desuperheater described herein includes a vortex suppression apparatus adjacent an end of a body of the desuperheater.
  • the vortex suppression apparatus suppresses or significantly reduces vortex shedding to alter or attenuate a resonant vortex induced vibration and associated magnification of the steady drag and/or disrupt or prevent formation of a vortex street (e.g., a two-dimensional vortex street or wake).
  • a vortex suppression apparatus is integrally formed with the body of the desuperheater.
  • the vortex suppression apparatus may include a helical strake, a plurality of ribs, splines, a plurality of protruding surfaces (e.g., curved surfaces), a plurality of apertures and/or any other suitable geometry or shape to suppress or significantly reduce vortex shedding that may otherwise develop as fluid flows across the body of the desuperheater.
  • the desuperheater and/or the vortex suppression apparatus may be made of metal (e.g., stainless steel) and the vortex suppression apparatus may be formed with, or coupled to, a body of the desuperheater via, for example, machining, welding, casting and/or any other suitable manufacturing process(es).

  • the first end 118 includes a flange portion 122 that is disposed between the flanges 106 and 108 to couple the desuperheater 102 to the pipeline 104 .
  • the body 114 when coupled to the pipeline 104 , the body 114 is suspended within a fluid flow path 124 substantially perpendicular to the direction of the superheated fluid flowing through the fluid flow path 124 .
  • the second end 120 of the body 114 is not secured or otherwise coupled to the pipeline 104 and may flex, bend and/or move relative to a longitudinal axis 126 during operation.
  • the superheated fluid flows across the body 114 of the desuperheater 102 at a relatively high velocity between the inlet 110 and the outlet 112 at a superheated temperature (e.g., a temperature above the saturation temperature of the fluid).

  • unsteady flow can generate separated or detached flow over a substantial portion of the body 114 , which can cause vortex shedding.
  • Vortex shedding may produce a fluid flow field having a vortex street (e.g., a two-dimensional vortex street or wake) downstream from the body 114 that induces or causes fluctuating pressures or vibrations (e.g., a eddy flow) to be imparted on the body 114 .
  • a vortex street e.g., a two-dimensional vortex street or wake
  • fluctuating pressures or vibrations e.g., a eddy flow

  • asymmetrical vortex shedding often develops or creates an oscillating flow characteristic having a discrete or shedding frequency that can cause the body 114 to oscillate or vibrate during operation.
  • These vortices or oscillating fluid flows can create harmful periodic forces or vibrations that are imparted on the body 114 of the desuperheater 102 .
  • such forces can cause excessive vibrations and/or lift forces to be imparted against the body 114 .
  • a shedding frequency of vortices that is substantially similar or identical to a natural frequency of the body 114 of the desuperheater 102 creates a resonant vibration that causes the body 114 to vibrate or oscillate in a violent manner, causing the body 114 to break, fracture and/or otherwise become damaged.
