Superheated steam is a steam at a temperature higher than its vaporization (boiling) point at the absolute pressure where the temperature is measured. Continued heat input will then "super" heat the dry saturated steam.
What is the difference between dry and wet steam?
Dry steam is steam that is at the temperature of saturation, but does not contain water particles in suspension. It has a very high dryness fraction, with almost no moisture. Commercially, dry steam contains not more than one half of one percent moisture.
Is Steam the same as saturated vapor?
Vapour is a substance in gas phase under its critical temperature. Saturated steam is a combination of water vapour and liquid water in equilibrium. Superheated steam has only the vapour since it's at a higher temperature than the saturation temperature. Steam= Gaseous State of water beyond boiling point.
