The Copes-Vulcan Mechanical Atomizing Desuperheater range is generally used for applications which feature steady loads.
Description
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).
Principle of Operation
Description
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).
Description
The MA-III/MA-IIIU is a multi nozzle mechanical atomizing desuperheater that reduces steam or gas temperatures by introducing cooling liquids directly into the hot fluid. The MA-III/MAIIIU is a probe style direct contact heat exchanger. The liquid passes through the main tube of the desuperheater to the spray nozzles and discharges into the steam header.
The MA-III/MA-IIIU is generally used for applications which feature steady and transient loads. The primary use is for interstage attemperation of high pressure and temperature superheated steam and is specially designed for intermittent use. It is well suited for applications where limited differential pressure is available for injection purposes. The MA-III/MA-IIIU is also designed for higher capacities than the MA-I and SAMN at the same time supporting wider range of the liquid flows.
This model is available in two mounting options. The MA-III is designed for welding to the pipe line and the MA-IIIU is flange mounted. The MA-IIIU also offers mounting commonality with other U-series desuperheaters (MA-IU, MA-IIU, MNSD-V and SAMN-U).
