Condensing steam turbines are used if the turbine is utilised solely for power generation i.e. it is connected to a generator and does not provide process steam to the plant. Unfortunately, the exhaust steam of condenser steam turbines must be condensed prior to being returned to the boiler (this is where condenser turbines obtain their name).

The Rankine cycle system consists of a pump, boiler, turbine, and condenser. The pump delivers liquid water to the boiler. The boiler heated by the solar heat converts water to superheated steam. This steam is used to run the turbine which powers the generator. Steam leaves the turbine and becomes cooled to liquid state in the condenser.

The use of a condenser in a power plant is to improve the efficiency of the power plant by decreasing the exhaust pressure of the steam below atmospheric pressure. Another advantage of the condenser is that the steam condensed may be recovered to provide a source of pure feed water to the boiler and reduce the water softening capacity to a

The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam. The nozzle acts

In a fossil power plant coal is burnt in boiler furnace to produce heat which boils the water in the boiler to produce high pressure & high temperature steam. This steam is expanded across a number of turbine blades and the spent steam is condensed in a condenser and pumped back to the steam - water cycle of the plant.
