Aatmospheric drain tank
Bmain and/or auxiliary condenser
Cdeaerating feed water heater
Dmakeup feed water tank
AI Explanation
The correct answer is A) atmospheric drain tank. When live steam is supplied directly to the tank heating coils, the collected drains in the 'clean' section of the contaminated drain inspection tank are removed directly to the atmospheric drain tank. This is because the live steam introduced to the tank heating coils can potentially become contaminated, and the collected drains need to be directed to a tank where the contaminants can be properly disposed of, rather than being recirculated back into the system. The other answer choices, such as the main/auxiliary condenser, deaerating feed water heater, or makeup feed water tank, are not the appropriate destinations for these potentially contaminated drains.
