We know that steam is the gaseous phase of water, so it has water in it. It also has considerable thermal energy, too, as water must be heated quite a bit (at STP) to turn it into steam. It is the thermal energy in steam which we use to drive so many different things, like turbines to generate electric power.

When water is heated, there is a relation between temperature and pressure at which the water and steam are in equilibrium. This applies up to 374 degC at which the corresponding pressure is 222 bar abs or 3220 psi abs. Beyond this temperature liquid water cannot exist and the steam is said to be supercritical.

At any temperature between 100 degC and 374 degC there will therefore be a pressure at which steam is just formed and this is said to be dry saturated steam. It is saturated because if the temperature drops even slightly at the same pressure, steam will condense. If at this same pressure the steam is further heated, it is said to be superheated because it is at a temperature higher than dry saturated steam would be. Superheated steam is desirable for use in steam turbines, because it prevents formation of water droplets as the steam is expanded through the turbine-the droplets could damage the turbine blades.

In the supercritical region above 374 degC steam will always exist whatever the pressure, so the concept of superheat does not apply here.

Steam is made by evaporating water.........Once the liquid reaches a boiling point it turns to vapor

H2O, water.

It's called steam when the vapor pressure of the water equals or exceeds atmospheric pressure.

What is difference between radial flow turbine and axial flow turbine?

in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.


What is mean by supersaturated flow?

When dry and saturated steam is caused to expand in a nozzle,the actual measured steam flow is found to be greater than the theoretical calculated flow.This is due to the time lag in the condensation of steam & the steam remains in dry state instead of wet. Such a steam is called supersaturated steam. This time lag is cause due to the the face that, the converging part of the nozzle is to short and the steam velocity is too high that the molecules of steam have insufficient time to form droplets.
