Steam Conditioning and Desuperheating

admin — Wed, 20 May 2026 11:46:44 +0000

A desuperheater injects a controlled, predetermined amount of water into a steam flow to lower the temperature of the steam. To achieve this efficiently, the desuperheater must be designed and selected correctly for the application. Although it can appear simplistic in design, the desuperheater must integrate with a wide variety of complex thermal and flow dynamic variables to be effective. Steam conditioning valves control steam pressure and temperature by combining both functions within one integral control unit. These valves address the need for better control of steam conditions brought on by increased energy costs and more rigorous plant operation. Steam conditioning valves also provide better temperature control, improved noise abatement, and require fewer piping and installation restrictions than the equivalent desuperheater.

Rotary Control Valves

A rotary control ball valve consists of a valve body with a rotatable ball to control flow. A ball valve as a throttling control device ideally uses a full port (full bore) or reduced port (reduced bore) mechanism. A port or bore is a cylindrical flow passage through the center of the ball, and when turned one-quarter of the way, the flow stops. The port of a full port or full bore ball valve equals the pipeline diameter and presents little or no restriction to flow to allow for pigging when not attenuated. The port of reduced port or reduced bore ball valve is smaller than the pipe to absorb a small amount of pressure drop.

Globe Control Valves

Throttling globe control valve A throttling globe control valve uses a linear motion to move a closure member into and out of a seating surface. They have a body distinguished by a globular-shaped cavity around the port region and are designed to regulate process flow when used in conjunction with an actuator assembly. Many single-seated valve bodies use cage or retainer-style construction to retain the seat-ring, provide valve plug guiding, and provide a means for establishing particular valve flow characteristics. Cage or retainer-style single-seated valve bodies can also be easily modified by change of trim parts to change the flow characteristic or provide reduced-capacity flow, noise attenuation, or reduction or elimination of cavitation.
