Question 73Steam Plants - QMED70% to pass

The atmospheric drain tank (ADT) normally drains to the _______________.

AI Explanation
You are correct, the answer is A) main and/or auxiliary condenser. The atmospheric drain tank (ADT) is designed to collect and drain any water, steam, or condensate from various components of the steam system. This drained fluid is then directed to the main or auxiliary condenser, where it can be re-used in the steam cycle. The other options are incorrect because: B) the air ejector condenser is a separate system used to remove noncondensable gases, not for draining the ADT; C) the reserve feed tanks are for storing and supplying boiler feedwater, not receiving drainage from the ADT; and D) the distillate tank is used to store pure distilled water, not for receiving drainage from the ADT.
