Efficiency curves for steam turbine

[richdrake]

I am modeling a steam turbine, and would like find typical efficiency curves for a single stage and multi-stage steam turbine, power at 38MW, (but the power is not too important). I am specifically looking for efficiency vs flow rate curves, does anyone have info they could share or a data set I could generate my own curve from.

Would be most grateful... Thx

Don't know if you'll see this given it's been a while since you posted the question but the efficiency of a steam turbine is a function of the inlet steam temperature and pressure, outlet pressure and MW rating (larger units are more efficient than smaller units).

If you have a copy of the GPSA data books (or can find a copy), they have information on this under section 15 - Prime movers

Thanks TD2K, willsearch for the books and go from there. have already had a goodsearch around but not read the books you suggest as yet.

Thx again.

If you want to post your inlet steam conditions (pressure and temperature) and outlet pressure, I'll look through my books and let you know what they say.
