Answer / kanhaikumar

urbine blades are arranged
in multiple stages in
series, called compounding,
which greatly improves
efficiency at low speeds. A
reaction stage is a row of
fixed nozzles followed by a
row of moving nozzles.
Multiple reaction stages
divide the pressure drop
between the steam inlet and
exhaust into numerous small
drops, resulting in a
pressure-compounded
turbine. Impulse stages may
be either pressure-
compounded, velocity-
compounded, or pressure-
velocity compounded. A
pressure-compounded impulse
stage is a row of fixed
nozzles followed by a row
of moving blades, with
multiple stages for
compounding. This is also
known as a Rateau turbine,
after its inventor. A
velocity-compounded impulse
stage (invented by Curtis
and also called a "Curtis
wheel") is a row of fixed
nozzles followed by two or
more rows of moving blades
alternating with rows of
fixed blades. This divides
the velocity drop across
the stage into several
smaller drops. A series of
velocity-compounded impulse
stages is called a pressure-
velocity compounded turbine.

Answer / abdul hameed

Stage is a set of Fixed & moving row of blades.
Fixed blade act as guide or as Nozzle. Moving blade is a mechanical energy imparting member.
