A solar-heated steam-electric generating plant heats steam to 250 C After passing through the turbine cooling towers cool the steam to 30 C?
The steam at 250Degc does it work and gets converted to mechanical energy by the turbine and to increase the efiiciency of the turbine the pressure is mentained below atmosphearic pressure at the exhust. It is not cost benificaial to handle (pump) this steam coming out of the exhust thus needs to be cooled to take it to liquide stage by cooling towers.
