Mechanical Atomizing Desuperheaters
 |
The Copes-Vulcan MA-I/MA-IU Mechanical Desuperheater is generally used for attemporating applications featuring steady loads. It is particularly designed for rugged service and can maintain final temperature to within 20°F (11°C) of saturation. Maximum cooling liquid capacity is 25,860 lbs/hr (11,700 kg/hr)
at a nozzle differential pressure of 160 psi (1100 kPa) when using
100°F (38°C) water. Multiple units or other models can be installed
in a header for higher capacities. |
 |
| This model is available in two mounting options. The MA-I
is designed for welding to the pipe line and the MA-IU is flange mounted.
The MA-IU also offers mounting commonality with other ‘U’-series
desuperheaters (MA-IIU, MNSD-V and SAMN-U).

The Copes-Vulcan MA-II/MA-IIU is a mechanical atomizing desuperheater that is generally used for applications which feature steady loads. It is particularly designed for rugged service and can maintain final temperature to within 20°F (11°C) of saturation. In addition to steady load service, it is often used for attemporating applications, and performs equally well for both. Maximum cooling liquid capacity is 175,000 lb/hr (80,000 kg/hr) at a nozzle differential pressure of 400 psi (2760 kPa) when using 100°F (38°C) water. This model is available in two mounting options. The MA-II is designed
for welding to the pipe line and the MA-IIU is flange mounted. The MA-IIU
also offers mounting commonality with other ‘U’-series desuperheaters
(MA-IU, MNSD-V and SAMN-U). |

The Copes-Vulcan MA-IIIU Mechanical Atomizing Desuperheaters reduce steam or gas temperatures by introducing cooling liquids directly into the hot vapor. The MA-IIIU is a probe style direct contact heat exchanger and is mounted by a universal flanged connection. The liquid passes through the main tube of the desuperheater to the spray nozzles and discharges into the header. The MA-IIIU is generally used for applications which feature steady and variable loads. The primary use is for interstage attemperation of high pressure and temperature superheated steam and is specially designed for intermittent use. Bulletin PS-60 - Product Specification Sheet (526KB)
