The pumping issue of the turbine steam seal extractor
Thread Content
Is it better to install the extractor of the steam seal extractor in front of or behind the cooler?
The front part is better; we use electric vacuum pumps
The pump we use is steam-powered; it is essentially a steam ejector that creates a vacuum to draw out the steam that leaks from the turbine. Cooling water flows through coiled tubes to provide direct cooling. Please advise
The steam seal extractor of our unit is installed in front of the cooler; I think that if it were installed behind the cooler, water would appear at the inlet of the extractor, which would affect its operation.
An has an energy-saving effect; the conversion of steam into water generates a certain negative pressure.
We use it after water cooling----mechanical vacuum pumping is employed----
