Power Generation/Steam Power/Part4

This is the more preffered Cooling method which is now being implemented in most new Steam power stations. Steam is circulated inside a radiator-like heat exchanger and is cooled by the natural cold air blown (naturally or using draught fans) between pipes of the heat exchanger. The cooled/condensed steam is returned to the boiler(Rankine cycyle).

This method greatly decreases water wastages through evaporation by almost 84% of the wet cooling method. It is called Direct dry cooling since the condenser has been eliminated completely. This method is favored where water is scarce.
