in the thermal power plant, why we use the condenser (for
cooling the steam) when we have to heat the steam again.
i mean why we are cooling the steam,

Answer Posted / abolfazl ghasemi

Because Thermal power plant works in Rankin Cycle. And in Rankin cycle, the efficiency depends on the temperature and pressure in cold and warm points.(Boiler and Condenser).
And in condenser we distillate steam by spraying water on it to change it from steam phase to liquid and during this volume decrease (steam to water) we make vacuum or low pressure. So the surrounded area of the curve increases and efficiency goes upper.
Also we can save purified water. At the end we can add make up water and control the water demand of cycle.
Thank you for attending
