Selecting the most efficiency desuperheater operation is important to consider. After all, it is part of a system made up of many other parts, although it plays an important role in your production process. But how do you choose the right one? Consider these handy guidelines.
Turndown for what? Maximum and minimum flows affect your costs more than anything else at first. But this is an area where you shouldn’t pay for performance margin you don’t need. You don’t need 80% flow rate if your needs only amount to 10%, so determine your true turndown.
How does it fit in to the bigger picture? Desuperheaters do not act on their own – they are part of a complex system that needs to be carefully engineered. Ensure that every part, such as your steam pressure reducing valve to your pressure sensing element, are positioned properly and fit the specs you’ve established for your desuperheater.
Know your steam. If you have to have saturated steam, then it needs to be specified wherever possible. If that isn’t possible, then keep residual superheat in the system as high above saturation as possible. In an ideal situation, you won’t need any residual superheat, as it greatly reduces your costs. If you don’t need critical control of residual superheat, then specify the heat up to the tolerance level. But if you must control it that is usually when problems occur. In those instances, it is important to ensure the other elements of your production process – the valves, controllers and piping – are working at peak performance.
