DESCRIPTION The Copes-Vulcan Multiple Nozzle Spray Desuperheater offers optimum performance and rangeability in a variable spray tube design. The MNSD fills the performance gap between the limited capability of a simple mechanical spray type desuperheater and the virtually unlimited capability of Copes-Vulcan’s Variable Orifice Desuperheater. The MNSD offers high temperature capabilities and up to Class V leakage rating.
Steam Atomizing Desuperheater SA-35
E
DESCRIPTION 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.
Spring Assisted, Multiple Nozzle Spray
Desuperheater SAMN-U DESCRIPTION
The spring assisted multiple nozzle desuperheater reduces steam or gas temperatures by introducing cooling liquids directly into the hot vapor. Copes-Vulcan's SAMN-U has six nozzles which can be opened or closed to vary the coolant flow. This provides a higher turndown than single nozzle units where the amount of coolant flow is dependent only on the ability to vary the pressure drop across the nozzle.
SAMN-U contains an integral spring loaded flow plug which moves in response to a change in pressure differential between the coolant inlet pressure and the main header pressure. As the plug moves, more or less nozzles are uncovered introducing more or less coolant into the main header. The cooling water inlet pressure is controlled by a Copes-Vulcan Severe Duty or General Service Globe Valve.
