Corrosion and Scaling. As steam evaporates from the boiler drum, it leaves back the impurities in the drum. When steam is wet, the water droplets have the impurities dissolved in them. These impurities get carried into the steam network and process equipment.

The entropy of wet steam can be expresses as: dS = log e (T 1 /273) + ζ(L 1 /T 1) (4) where. ζ = dryness fraction. Entropy of superheated steam. Change of entropy during super-heating can be …
WebDryness Fraction: The term dryness fraction is related with wet steam. It is definedas the ratio of the mass of actual dry steam to the mass of steam containing it. It is usuallyexpressed by the symbol ‘x’ or ‘q’. If m s =Mass of dry steam contained in steam considered and m w =weight of water particles in suspension in the steam considered Then
WebThe acceptance criterion for steam dryness (the fraction of steam relative to water – 1.0 = all steam, no water) is at least 0.95, or 95% by weight.
