Max Discharge Pressure - Turbine Driven Pump
Max Discharge Pressure - Turbine Driven Pump
(OP)
This may be a dumb question
but is it reasonable to expect a pump discharge pressure to exceed the turbine supply pressure?
or stated differently
can the discharge pressure exceed 135-psig if the turbine is driven with 135-psig steam?

Yes, the disharge pressure on the fluid side can be greater than the steam pressure at the inlet of the steam turbine.

RE: Max Discharge Pressure - Turbine Driven Pump
I can recall a BFP turbine driven pump set on a ~800 MW Supercritical unit that produced about 5500 PSIG discharge pressure with something like ~150 psi (extraction) steam.
How's that for turn-up?
I can't recall any more diverse than that.
