2/8/2021 · This fraction is used to quantify the amount of water within steam. For example, if steam contains 15% water by mass, it's said to be 85% dry, or have a dryness fraction of 0.85. Steam dryness is really important as it has direct correlation with the amount of transferable energy comprised by steam that governs quality and efficiency of heat.

The steam dryness fraction is used to quantify the amount of water within steam. Dry steam - all water molecules are in the gaseous state; Wet steam - a portion of the water molecules have lost their energy - latent heat - and condensed to tiny water droplets; To produce dry steam in an boiler and keep the steam dry throughout the piping system is in general not possible.
