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 / ramandeep singh
There are many reasons for not reheating steam
1.According to thermodynamics law there should be heat source and sink.Boiler as source and condensor as sink.
2.There are non condensable gases which are to be removed otherwise they will damage boiler tubes.
3.As thermal power plant works on rankine cycle so as much pressure and temperature drop is there as improved will be efficiency and in case of condensor there is vaccumm being created by ejector so pressure drop is substantial.
4.WE can use steam from some intermediate stage (Bleed) to heat feed water and deaeration or for reheating in boiler .
