Design of extraction and Induction STG
Design of extraction and Induction STG
(OP)
Dear all,
From the site steam balance, the best design of a new steam turbine generator rated at 65 MW with inlet steam at 625 psia and extraction at 375 psia and induction induction at 75 psia and condensing stage.
My question is: is this new steam turbine generator can be designed easily or not, what would be the added cost and complexity of the control for this configuration compared to an induction with no extraction.
regards,
Mana

RE: Design of extraction and Induction STG
There are only a handful of manufactures capable of designing and building that type of turbine.
from the steam conditions I assume this is in some sort of paper mill?

Pay for a consultant for a solid final recommendation ... before purchase !!!
Like older mechanical engineers, many steam turbines 50-60+ years old can still be very useful ....
Extraction steam ports can operate at a variety of conditions.
You should have a firm idea of the maximum expected massflow into/out of each port .... There is a minimum steam flow that must go all the way through the machine to maintain stable operations
