Calculate the Theoretical Minimum Steam Flow to a Condensing Steam Turbine
Calculate the Theoretical Minimum Steam Flow to a Condensing Steam Turbine
(OP)
Could one share his approach in "Calculating the Theoretical Minimum Steam Flow to a Condensing Steam Turbine"?
The web is full of "artistic" comments of this minimum flow to be about 25% rating of full-load limits.
But one help elaborate on a methodical way of computing (Mathematical Formulation) the theoretical minimum steam flow required to guarantee a stable operation of a given Condensing Steam Turbine?
Certainly Diaphragm size, Nozzles geometry, Number of Stages, Synchronous speed should affect this minimum flow.
Thank you all for your contribution.

Depends too much on cooling water temeprature, flow rate, dew point and atmospheric pressure (effectiveness of the cooling system) and the specific efficiencies and problems of the last two turbine blade rows: Erosion, wetness, particle size, etc.
Better to run a low power test series for winter, spring, fall, summer conditions.

@snoopnoon Exhaust temperatures are below 45C (113F) and wet. Bearing temperature are stable... and vibration occurs.

It seems someone with years of operating and troubleshooting experience is needed to visit the site and figure out what's happenieng and how to fix it, as in a consultant...and finding a knowledgeable one can be a tall order.
Any reader recommendations for the OP?
