Answer / devanesan

throttling of control valve will reduce the turbine
efficiency. while throttling the throttling loss will be
there due to pressure drop across the valve. the vave will
acting as a nozzle. there after there is no kinetic energy
utilisation before first stage fix and moving blade. again
the pressure is reduced and velocity increased in first
stage fix blade. so by throttling the efficiency will
reduced.

Answer / p.natarajan

Throttling of steam from a higher pressure to a lower
pressure involves irreversible energy loss. Instead of
generating a high pressure steam with low enthalpy and
throttling it to a lower pressure (with same enthalpy), steam
at a lower pressure (with a higher enthalpy) will do more
work per kg with same exhaust pressure. This can be verified
with any Steam table or Mollier chart.
