THREE MAJOR INPUTS TO POWER STATION: 1) Water : Water has been taken from near by Yamuna Canal This water is lifted by raw water pumps and is sent to clarifier to remove turbidity of water The clear water is sent to water treatment plant, cooling water system and service water system The water is de-mineralized (DM) by water treatment plant
An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tub The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC In thermal power plants (T), the steam from the turbine exhaust flows into the ACC where condensation occurs
GE's condensers have been used in power plants for over 50 years, and have a track record of high performance Read more about their design from GE Steam Power
In the cooling towers an airflow, natural or forced, cools the water and the water returns to the condenser Power plants located away from large sources of water utilise this type The large concrete hyperbolic towers that you see near thermal power plants are used for cooling the circulating water The advantages are :

Circulating Water Pumps Main Condenser (A and B) 12 System Overview The purpose of the Circulating Water System is to remove heat from the power plant steam cycle by circulating cooling water through the tubes of the main condenser The system removes the latent heat of ,
A thermal power station is a power station in which heat energy is converted to electric powerIn most of the places in the world the turbine is steam-drivenWater is heated, turns into steam and spins a steam turbine which drives an electrical generatorAfter it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle
used condensers in modern power plants The exhaust steam from the turbine flows on the shell side (under vacuum) of the condenser, while the plant’s circulating water flows in the Tube side The source of the circulating water can be either a closed-loop (ie cooling tower, spray pond, etc) or once
Water-cooled condensers involve a heat rejection loop where condenser heat is dissipated to the environment via water The most common type of water-cooled condensers in geothermal power plants are direct-contact and surface typ Plate-type heat exchangers (a special kind of surface exchanger) are also possible, but appear to be more common in liquid-to-liquid heat transfer ,
