Desuperheater is precision-engineered equipment that involves introducing a controlled volume of water into the steam flow to reduce its temperature. For proper operation, it needs to combine various complex thermal and variable flow rate variables. The efficient steam conditioning valves help manage steam pressures and temperatures inside the unit. They also facilitate enhanced noise reduction and reduced piping and installation needs.

Hence the selection of the right desuperheater can ensure operational and energy efficiencies.

Factors influencing the right choice

We have identified the following factors that help decide the right choice for a desuperheater:

1. Orientation of the desuperheater – Your existing setup can demand horizontal (new designs), or vertical (retrofitting in existing setups) orientations for your desuperheater.
2. Straight-line length – Your custom installation will need to consider the void space available with your existing setup. And similarly, your design for a new setup will need to provide suitable space for upstream and downstream.
3. Turndown requirement – You can look at installing a future-proof desuperheater system by allowing a maximum duty of around 100 t/h superheated steam flow rate for a stress-free operation up to 5 years at a stretch. Obviously, such a choice has to be in sync with your plant’s performance. Otherwise, it makes sense to install a lower capacity unit that has a provision for swapping with a different unit as and when the need arises.
4. Size of the steam line – Depending on the choice of a desuperheater, your requirement for steam line sizing may vary.
5. Further factors worth considering are the custom plat requirements like line layouts, steam and cooling water pressures, and heat transfer distance.

Making the right Steam Desuperheater choice

The Komax steam desuperheater deploys a multiple-stage mixing system through its patented Komax Equalizer Mixing Module. The resultant is the fast absorption of water into steam. It also helps manage the stress in the piping because water does not settle at the bottom of the pipeline.

Further diminishing the need to install expensive thermal liners. Komax desuperheaters can include thermal liners if the client requests the same.
