Impulse turbine stages
Impulse turbine stages
(OP)
Hi,
I am confused about stages in an impulse turbine.
Generally in industry i have seen that an impulse turbine with single rotor having 2 rows of buckets is called a single stage.(curtis stage)
My concept is that nozzle + rotor is a stage.
if we have one set of nozzles and 3 rotors then it is one stage..
but if we have 2 nozzles & 2 rotors we have 2 stages.am I right?

RE: Impulse turbine stages
For multi-stage turbines of impulse design, the stages downstream of the control stage will be Rateau Stages. Each Rateau Stage consists of a set of stationary nozzles (diaphragm) and one rotating row of blades.
Best of luck!
RE: Impulse turbine stages
To the OP, you are correct. The diagram you attached would be a single stage.
