Question

What does steam saturation temperature mean?? thanks?

Answer 1

Read this page. This is being explained to a reasonable degree.

Answer 2

saturation temperature is nothing but the temp at which addition of heat result in change of phase......well for water the change of phase will result in vapor at saturation temp.......................................

for steam the addition of heat result in superheated steam..........thus  .....the temperature above which the steam is superheated is called steam saturation temperature.

additional info: Superheated steam is steam that is at a temperature higher than the saturation temperature for the steam pressure. For example, steam at a pressure of 3 bar g has a saturation temperature of 143.762°C. If further heat were to be added to this steam and the pressure remained at 3 bar g, it would become superheated....

hope helpful

Answer 3

It means that 'The Temperature of Water and its Vapour Pressure are in Equilibrium'.

Saturated steam is produced when the Water temperature is 'In Equilibrium' with the Surrounding Pressure.

Equilibrium occurs when the number of molecules leaving the liquid into the vapour phase is equal to the number of molecules returning to the liquid, at a specific temperature.

Steam at 1 atmosphere and 100°C is Saturated Steam.

When pressure is increased, the boiling point increases.

The new Specific temperature at the higher pressure will be in equilibrium with the pressure and the steam liberated will still be Saturated.

(Saturated steam can however, be increased in temperature without further increasing pressure to come 'Out of Equilibrium' and become 'Superheated steam').

(Working on steam turbines for many years, we produced Saturated steam at 252°C (486°F) and 630psi.

This was then Superheated to 770°C at 630psi for driving 40,000 horsepower Refrigeration compressors for the production of Liquefied Natural Gas).

Answer 4

The steam saturation temperature is the temperature at which steam begins to condense (or water begins to boil) for a given pressure, or more specifically, the temperature at which a liquid-vapor phase change occurs in water.
