What is the range of efficiency of thermal or steam power plants? Why it is so low?..

Answer / iamdon

By employing super critical technology( Temperature more
than 600 degree celcius and pressure of steam 30 N/mm2 )
overall efficiency upto 50% can be achieved but in rest of
the cases the efficiency is well below 50%.
The range of efficiency of steam power plants is 30-50 %.
The typical value is 35%.

The reason of low efficiency is statistically stated as.
Approx 10% of heat is lost with flue gases.
Approx 50% of heat is lost in condensor.
These two are mainly responsible for low overall efficiency
of steam power plants.

Thermal cycle(Rankine cycle) efficiency=30-40%
Generator and Turbine efficiency=90% +
