Process heating is vital in a multitude of different industries. It involves using thermal energy for a variety of applications, such as drying or curing, distillation, annealing, and more. Many businesses rely on steam here because it’s cost effective, easy to work with, and offers impressive efficiency. However, they may need a steam boiler silencer to address noise and improve performance.
A key thing to understand is there are actually a number of different types of steam. They differ mainly because of the amount of moisture. Some types even include additives due to the specific application. Let’s have a closer look.
Wet steam
Firstly, we have the most basic form, also known as unsaturated steam. In the simplest terms, it means it still contains some water molecules. This is generally a fine mist or droplets. It happens because the boiler does not heat the liquid up enough to fully vaporise all water molecules.
There are a few crucial things to keep in mind about wet steam. Most importantly, it typically doesn’t have as much enthalpy (heat energy). That means it is less efficient, so it’s best for low energy applications. On top of that, the water content means there is a higher risk of corrosion.

Dry steam
Next up we have saturated steam. The notable thing here is it has much lower moisture content, sometimes just 5%. Producing it involves first heating water in a boiler. Then, there is an additional step to vaporise it (latent heating). This ensures that all the molecules are gaseous, with no mist or water droplets.
Dry steam provides some impressive advantages. Crucially, it has a lot of enthalpy and transfers energy efficiently. Therefore, it is useful for high energy applications. The low moisture content means it is suitable for a wider array of uses too, including electronics and chemicals.
Superheated steam
Finally, we have steam with a third step. It’s the same as producing dry steam, but then there is further heating. This increases the temperature beyond the vaporisation point, ensuring practically all moisture is gone. If you need one, discuss steam boiler silencer design with us.
The most important advantage with superheated steam is it’s got the most energy. It is hotter and drier, making it ideal for the hottest applications and situations where you need to avoid condensation to prevent corrosion. Generally, it’s best for power generation to avoid damage to turbines and processes like sterilisation.
Some unique types
While those three are the broad types of steam, there are a few other specific varieties for different applications. They are generally variations of dry and superheated.
One of the most notable options is culinary steam. It’s made from clean water to ensure it has very few impurities. In some cases additives are used, but filtered from the steam. Ultimately, the goal is to ensure safer production of food and sterilisation of key things like bottles or cans.
Another interesting option is pure steam. It’s a step further than culinary, ensuring there are no impurities. As a result, it is the best option for pharmaceutical and medical applications as there is no risk of contamination.
Talk to the experts about designing a steam boiler silencer
Now you know a lot more about the different types of steam for process heating applications. They all have their uses in all kinds of industries. Businesses need to think carefully about which type they use, and how to produce and utilise it safely and efficiently.
A crucial thing to look at is the noise. Working with steam can create issues, particularly noisy boilers and safety valves. It can be harmful to people, especially releasing steam into the atmosphere. So, it may be necessary to choose a steam boiler silencer or models for safety valves and vents. It can reduce the noise and make workplaces safer.
