70% to passThe gland exhaust fan draws steam and non-condensable vapors from the gland exhaust condenser and discharges to the _______________.
Aatmosphere
Bmain condenser
Cvent condenser
Datmospheric drain tank
AI Explanation
The correct answer is A) atmosphere. The gland exhaust fan draws steam and non-condensable vapors from the gland exhaust condenser and discharges them to the atmosphere. This is because the gland exhaust condenser is designed to remove these vapors from the main steam system, and the gland exhaust fan provides the necessary suction to pull them out and vent them overboard. The other options are incorrect because: B) the main condenser is a separate system that condenses the main steam, C) the vent condenser is not involved in this process, and D) the atmospheric drain tank is for collecting condensate, not venting non-condensable gases.
