Steam Power Plants 103 power plants, power is generated by alternately vaporizing and condensing a working fl uid (in many cases water, although refrigerants such as ammonia may also be used) [1]. There are four processes in the Rankine cycle, each changing the state of the working fl uid. These states are identifi ed by number in Fig. 1.

A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated.
