Which system provides a means of removing non-condensable gases released during the condensing process?

• A. Main engine gland exhaust system
• B. Gland seal regulating station
• C. Desuperheater
• D. Emergency feed pump system

Answer: (A)

Non-condensable gases must be vented from the condenser area to maintain vacuum and efficient condensation. The gland exhaust system provides a dedicated vent path for these gases that originate in the gland seals and surrounding condenser circuit, carrying them away to atmosphere or through an ejector as needed. This keeps the condenser pressure low and prevents non-condensables from hindering condensation. The gland seal regulating station mainly controls the pressure for the gland packing and isn’t primarily a vent for non-condensables. The desuperheater cools superheated steam, not remove gases from the condenser. The emergency feed pump system is for supplying feedwater to the boiler in emergencies and isn’t involved in venting non-condensables.
