Answer / mob
The stages of turbine are decided or designed for optimum
expansion or in other words to fully capture the chemical
energy of gases and convert them to mechanical energy. .
By providing more stages, ideally the final pressure and
temperature outputs would be reduced ultimately leading to
higher output and efficiency but in actual it is not so.
For the gases to travel through the stages a certain pre-
fixed pressure value determined by OEM is required and also
the final output pressure should be at a higher value
compared to ambient for the exhaust to move up the stack.
Also by adding extra stages, thermal degradation of
material at exhaust could occur.

Answer / ronak pujara
according to me, increasing the stages of turbine, keeping the pressure drop across the whole turbine same, pressure drop across each stage will reduce which will reduce the stage efficiency or blade efficiency of the turbine...hence chances of corrosion of the blades and pitting will increase...the size of the turbine also increases in turn...hence no of stages are decided on the basis of stage efficiency and pressure drop across each stage required...

Answer / azruddin
Turbine blades work as a capture to the accelerate hot air
coming out from the combustion so if the 110MW turbine
suitable good for the three stage turbine and we increase
to 6 stages, we will distrup the weight and the performence
of of gas turbine output and we need more modification on
it.

Answer / r2
the move compressor bleeds the better for the compressor
due the air that going in the combustion,and if the move
bleeds for the turbine you need move spare or large frame
and this will cost move in term of money...
