Steam Power
(OP)
A vendor quoted a steam turbine generator that will take 29,900 lb/h of saturated steam (300 psia/417°F) inlet & 40 psia/267°F saturated steam exhaust yielding between 700-800 kW electricity. My calcs only yield 290 kW (from steam tables)... what am I doing wrong?

I still do not understand how this can be "kind of" a condensing turbine.....????
Can you explain
Is there a true condenser, with a hotwell, pumps etc on the tail end of this machine ? Where does the discharge go ?
Or are you just in the thermodynamic range of condensate..?
??????????????????????????????

I am assuming the latter, no condensers, a skid unit to replace a PCV would consist of following: Single Stage Steam Turbine, Synchronous Generator (1,800 rpm rated @ 700 kW), Speed Reduction Gear, High & Low Speed Couplings.
We produce approx 29,900 lb/h of 285 psig saturated steam that is knocked down to 25 psig via a PCV. This vendor is stating he can replace the PCV & power our plant, so I am just now learning/researching the application. I thank you for the link.
Another concern is how the unit performs w/ significant fluctuation in the inlet flow rate (lb/h HP steam) with or without a VFD.

Is there anything else that you can drive with this steam?

the tricky part will be a load sharing system for when your power demands exceed you power production.
