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 / branesh kumar

Because the specific volume of steam is more for steam
compared to water.so if we are not condensing it,the
entire power generated by the turbine will be utilised only
to pump the steam.Also as per second law of
thermodynamics,there must be a source and a sink.Here
boiler acts as a source and condenser as a sink.
