Custom Steam Desuperheater
Desuperheater – Unlike conventional desuperheaters, Komax uses a multiple-stage mixing system using the patented Komax Equalizer Mixing Module. The first stage of mixing occurs at the water injection point; the water is sprayed upstream of the flow using low-pressure full cone spray nozzles to adequately distribute the water across the cross-section. Small droplets are sheared to then even smaller sizes using the velocity from the steam blowing the sprayed water downstream toward the Equalizer. The second stage of mixing occurs at the Equalizer. The equalizer consists of 6 mixing chambers with a helical mixing element in each chamber, which leads to 12 divisions and instances of increased turbulence between the steam and water. Thus, further shearing the water droplets to be effectively absorbed into the steam line. The third and last stage of mixing occurs at the Equalizer outlet. This is where the 12 streams recombine to blend together and then complete the mixing and water absorption to be carried downstream to the next part of your process.
The Desuperheater Creates Less Stress on Piping
Because of these mixing processes, we are able to significantly reduce the downstream requirements from approximately 30 pipe diameters to 10 pipe diameters before the temperature probe. The quick absorption of the water into the steam also greatly reduces the risk of stress in the piping due to thermal cycling, as water will not pool on the bottom of the pipeline. This removes the need for expensive thermal liners in the Komax Desuperheater, however, liners can be included in the design if desired.
Technical Specifications and Available Options for the Multi-Stage Mixing System
End Connection Options
- Flanged Ends: Flanged end connections allow for significantly easy mounting of the desuperheater into the process pipeline. As a general standard, metal desuperheaters have raised face flanges per ASME B16.5 or ASME B16.47 (for sizes larger than 24”) standards. Komax can also fabricate mixers to contain DIN (metric) flanges as well.
- Threaded Ends: Komax Systems offers male and female NPT end connections on desuperheaters as required.
- Weld Prep Ends: For custom configuration, Komax Systems offers weld prep end connections on Desuperheaters.
*All desuperheaters are made specifically per customer specification; end connection type can be made specifically per customer request.
