What is a gas-sealed cooler? Please let me know, experts.:loveliness::loveliness::loveliness:
A steam seal cooler is a device used in steam turbines. It is used to cool the steam seal at the shaft end
Oh, I see. Thank you...:loveliness: :loveliness: :loveliness:
The function of the steam seal cooler is to recover the steam that leaks from the shaft end steam seals, absorb its heat, and prevent this leaked steam from entering the bearing chamber and contaminating the oil, thereby protecting the safety of the bearings. It must maintain a certain (low) negative pressure during operation; at the same time, it also expels the air that has entered the shaft end. When adjusting this negative pressure, it is necessary to take into account changes in thermal expansion and vacuum levels.

Is there a more specific explanation?
The steam seal condenser is generally used together with a steam ejector to extract the seal air from the turbine shaft end
Not all turbines use steam seals to cool the steam; I’ve seen SIEMENS models that release the steam directly, which actually makes it easier to assess the condition of the steam seals.
