Steam Turbine
Steam turbines are devices which convert the energy
stored in steam into rotational mechanical energy.
These machines are widely used for the generation of
electricity in a number of different cycles, such
as:
* Rankin cycle
* Reheat cycle
* Regenerative cycle
* Combined cycle
The steam turbine may consists of several stages.
Each stage can be described by analyzing the
expansion of steam from a higher pressure to a lower
pressure. The steam may be wet, dry saturated or
superheated.
Consider the steam turbine shown in the cycle above.
The output power of the turbine at steady flow
condition is:
P = m (h1-h2)
where m is the mass flow of the steam through the
turbine and h1 and h2 are specific enthalpy of the
steam at inlet respective outlet of the turbine.
The efficiency of the steam turbines are often
described by the isentropic efficiency for expansion
process. The presence of water droplets in the steam
will reduce the efficiency of the turbine and cause
physical erosion of the blades. Therefore the
dryness fraction of the steam at the outlet of the
turbine should not be less than 0.9.

Advantages of steam turbines
- High efficiency at
high speed.
- Far fewer moving
parts, hence potentially
greater reliability.
- Conventional piston
steam locomotives give a
varying,
sinusoidal torque,
making wheel slip much
more likely when
starting.
- The side rods and
valve gear of
conventional steam
locomotives create
horizontal forces that
cannot be fully balanced
without substantially
increasing the vertical
forces on the track,
known as hammer blow
