Power Generation/Steam Power/Part3

This is the conventional cooling method used in most steam power stations. Steam of very high purity is cooled inside the condenser and is returned to the boiler(Rankine cycle).

The condenser itself uses cold water and employs the principle of heat exchange. As the cool water is returned to the boiler, the hot water in the condensor is pumped to the cooling tower. Here water is sprayed and thus falls down to the water pond under the cooling tower. As the water falls it is cooled by the natural cold air. The cooled water is pumped back to the condenser, and the cycle is repeated. This method uses a lot of water through evaporation.
