What is saturated steam and superheated steam?
Saturated steam is steam that is in equilibrium with heated water at the same pressure, i.e., it has not been heated above the boiling point for its pressure. This is in contrast to superheated steam, in which the steam (vapor) has been separated from the water droplets then additional heat has been added.
Why is saturated steam preferred to supersaturated steam?
Superheated steam is preferred over saturated steam because it can release a lot of its internal energy for work and remain above the liquid’s water vapor point (at a given pressure within the turbine/piston engine). Such droplets can also cause impact damage to mechanical elements of turbines and engines.
How do you convert superheated steam to saturated steam?
The solution is to supply the turbine with superheated steam at the inlet, and use the energy in the superheated portion to drive the rotor until the temperature/pressure conditions are close to saturation; and then exhaust the steam.
What temperature does steam become superheated?

Is steam superheated water?
At constant pressure, the temperature remains constant until all liquid water has been vaporized, i.e. until the steam is dry. Such steam at a temperature higher than its boiling point is called superheated steam.

Why is stewing a better method of cooking than boiling?
Simmering is a more gentle cooking method than boiling and is often used for long and slow cooking processes because there is less evaporation than with boiling. Tough meat, soups, and stews are often simmered over low heat for long periods of time.
What does stewing mean?
