Question 96Steam Plants - 1st Asst/Chief

The correct answer is A) atmosphere. In a steam-powered vessel, the air ejector unit is responsible for removing air and non-condensable gases that accumulate in the main condenser. The air ejector discharges this accumulated air directly to the atmosphere, rather than to any other part of the steam system. The other answer choices are incorrect because: B) The inter-condenser is a separate heat exchanger, not the proper discharge point for the air ejector. C) The high-pressure turbine is part of the steam propulsion system, not the air ejector system. D) The main condenser is where the air ejector removes the accumulated air from, not where it discharges to.
