IN A THERMAL POWER PLANT, WHY IS THE USED STEAM CONDENSED
INTO WATER AND THEN SENT BACK TO THE BOILER, WHY NOT
DIRECTLY REHEAT THE SAME STEAM??

Answer Posted / pjagan89

According to Second law of thermodynamics, There should be a
source and sink. Here Boiler acts as a source and condensor
acts as a sink.

If the Steam is not condensed, The power generated by the
turbine will be used to drive the pump to pump the fluid to
a higher pressure. Instead if we use a boiler it converts
the wet steam into a super heated steam. So, Both source a
nd sink are must.

ANSWER: According to Kelvin- Plank's statement,Steam has to
be condensed.
