What Does a Desuperheater Do?

Superheated steam is useful in many industrial applications, such as driving power-generating turbines. However, it must be cooled before being used for other purposes. A Komax Systems desuperheater allows you to cool superheated steam quickly and efficiently to your exact cooling requirements.

What Is a Desuperheater?

A desuperheater uses a liquid, typically water, to cool superheated steam to suitable temperatures the process requires. The steam absorbs water injected into the system via a spray nozzle, producing a cooling effect, and produces the desired steam temperature at the outlet of the desuperheater.

Desuperheater Specifications

We custom design and manufacture every Komax Systems desuperheater so that you can build a system to meet your specific cooling needs. The Komax desuperheater components can accommodate virtually any size inlet and outlet pipes, ranging from 2 inches to 48 inches, all included with an industry-leading mechanical and process warranty.

Additionally, we can manufacture your custom Komax desuperheater from a wide range of materials including:

  • Carbon Steel
  • Chrome-Moly
  • Stainless Steel
  • Alloy 20 Hastelloy
  • Inconel
  • Monel

Our end connection options include flanged per ASME B16.5 or ASME B16.47 (metric flanges available by request), NPT threads, or weld prep connections.

How Does a Desuperheater Work?

Our Komax Systems desuperheaters use the patented Komax Equalizer Mixing Module®, a multiple-stage mixing system that provides superior cooling by shearing and mixing water droplets for better absorption into steam lines.

The mixing module sprays temperature-regulated water upstream into superheated steam to start the cooling process. The steam and water mixture then moves into mixing chambers where the steam absorbs the water. The desuperheated steam then leaves the module and outlet of the desuperheater at the desired temperature.

When used inline between superheaters, a desuperheater acts as a steam attemperator to maintain the precise steam temperatures desired. The components are the same; however, attemperators must be incredibly precise to avoid damaging any equipment downstream of the boiler and desuperheater.

Where Are Desuperheaters Used?

Plants use a desuperheater anywhere they need to cool superheated steam to a more applicable working temperature. They are commonly installed after a boiler to bring steam to the desired temperature or upstream of turbines in power generation systems. Industries using desuperheaters to cool superheated steam include:
