Wet Steam vs. Dry Steam: The Importance of the Steam

When a steam boiler heats up water, bubbles breaking through the water surface will pull tiny water droplets in with the steam. Unless a superheater is used, this will cause the steam supply to become partially wet (wet steam) from the added liquid. Steam Dryness Fraction. The steam dryness fraction is used to quantify the amount of water within steam.
