SA-35 – Steam Assisted Desuperheater

The Copes-Vulcan SA-35 Steam Atomizing Desuperheater is used to reduce the temperature of vapors such as steam with condensate such as water. It was developed to obtain a more uniform spray under varying load conditions where no pressure drop in the steam header can be tolerated.

This desuperheater is made in four sizes, in pressure classes up to and including Class 1500.

*High Turndown

*Low Cooling Water Pressure Required

*Close Approach Temperature

*Close Temperature Control Tolerance

*Preheats The Cooling Water

*Eliminates Thermal Liners

Performance

*Turndown:  50:1

*Approach temperature:  90C

*Steam Velocity:  9 m/s

*Spray water Pressure:  >1 Bar

*Atomising Steam Pressure:  >6 Bar

Features

• High rangeability 25:1
• Shorter mixing distances than mechanical atomizing desuperheaters
• May be installed in either horizontal or vertical piping
• Temperature control to within 15º F (8.3º C) of saturation with the ability to hold set point within tolerance of 10º F (5.6º C)
